As more drivers and repair shops recognize the importance of braking safety, brake fluid replacement has become a maintenance item that requires more attention.<\/p>\n<p>The important point is that brake systems on current vehicles are not all the same. Traditional hydraulic systems, vacuum-assisted hydraulic systems, electronically controlled systems, EPB systems, brake-by-wire platforms, regenerative braking systems and pneumatic systems all have different structures. Because of that, the correct brake fluid replacement method also changes by system type.<\/p>\n<p>This guide explains what brake fluid does, why it must be replaced, which brake system types are common, and how replacement methods differ between traditional hydraulic systems and modern electronic brake systems.<\/p>\n<\/div>\n<nav aria-label=\"Article quick navigation\" class=\"ag-guide-strip\">\n<a class=\"ag-guide-card\" href=\"#brake-fluid-role\"><span class=\"ag-guide-card__num\">01<\/span><\/p>\n<h3 class=\"ag-guide-card__title\">Brake Fluid Role<\/h3>\n<p class=\"ag-guide-card__text\">Pressure transmission, heat resistance, corrosion protection and why fluid ages.<\/p>\n<p><\/a><br \/>\n<a class=\"ag-guide-card\" href=\"#system-types\"><span class=\"ag-guide-card__num\">02<\/span><\/p>\n<h3 class=\"ag-guide-card__title\">Brake Systems<\/h3>\n<p class=\"ag-guide-card__text\">Hydraulic, vacuum-assisted, electronic, EPB, brake-by-wire, regenerative and pneumatic systems.<\/p>\n<p><\/a><br \/>\n<a class=\"ag-guide-card\" href=\"#traditional-method\"><span class=\"ag-guide-card__num\">03<\/span><\/p>\n<h3 class=\"ag-guide-card__title\">Traditional Method<\/h3>\n<p class=\"ag-guide-card__text\">Brake fluid bleeder workflow for hydraulic and vacuum-assisted systems.<\/p>\n<p><\/a><br \/>\n<a class=\"ag-guide-card\" href=\"#electronic-method\"><span class=\"ag-guide-card__num\">04<\/span><\/p>\n<h3 class=\"ag-guide-card__title\">Electronic Method<\/h3>\n<p class=\"ag-guide-card__text\">Diagnostic tool plus brake fluid bleeder workflow for ABS, EPB and regenerative systems.<\/p>\n<p><\/a><br \/>\n<a class=\"ag-guide-card\" href=\"#troubleshooting\"><span class=\"ag-guide-card__num\">05<\/span><\/p>\n<h3 class=\"ag-guide-card__title\">Troubleshooting<\/h3>\n<p class=\"ag-guide-card__text\">Common post-service issues, causes and solutions.<\/p>\n<p><\/a><br \/>\n<\/nav>\n<\/section>\n<div class=\"ag-content-layout\">\n<div class=\"ag-content-main\">\n<section aria-labelledby=\"brake-fluid-role-title\" class=\"ag-block\" id=\"brake-fluid-role\">\n<div class=\"ag-section-header\">\n<span class=\"ag-section-kicker\">Foundation<\/span><br \/>\n<span aria-hidden=\"true\" class=\"ag-section-line\"><\/span><\/div>\n<article class=\"ag-richtext\">\n<p class=\"ag-eyebrow\">Why brake fluid matters<\/p>\n<h2 class=\"ag-heading\" id=\"brake-fluid-role-title\">The Role of Brake Fluid and the Necessity of Replacing It<\/h2>\n<p>Brake fluid plays a key role in transmitting pressure within the brake system. When the driver presses the brake pedal, the brake fluid quickly transfers force from the pedal to the brake calipers or brake drums, causing the brake pads to contact the brake discs or drums. This friction slows down or stops the vehicle.<\/p>\n<p>Brake fluid must maintain stable performance under heat. Braking generates a significant amount of temperature, and the fluid must avoid boiling or vaporizing. If vapor forms in the brake lines, brake pressure can become insufficient and braking performance can drop. Brake fluid also helps protect metal components from corrosion, extending the service life of the brake system.<\/p>\n<h3>Replace Brake Fluid to Maintain Optimal Brake Function<\/h3>\n<ul>\n<li><strong>Moisture absorption:<\/strong> Brake fluid absorbs moisture from the air. As moisture content increases, it can vaporize under high temperature and form bubbles in the brake lines. These bubbles make pressure transmission uneven, causing a soft brake pedal, longer braking distance and serious safety risk. A <a href=\"https:\/\/autoolstore.com\/sv\/product\/autool-as502-car-brake-fluid-tester\/\">brake fluid tester<\/a> is typically used to measure the moisture content in brake fluid.<\/li>\n<li><strong>Oxidation and degradation:<\/strong> Over time, oxidation changes brake fluid chemistry. Oxidized fluid may produce sediment or sludge that can block brake lines or brake system components, reducing flow and potentially leading to brake failure.<\/li>\n<li><strong>Contamination:<\/strong> The brake system is not completely sealed. Dust, impurities and other contaminants can enter the fluid during use, reducing performance and affecting normal brake operation.<\/li>\n<\/ul>\n<p>Experts commonly recommend replacing brake fluid every 2 to 3 years or after driving 40,000 to 60,000 kilometers. This is only a general guideline. The actual interval should be determined by vehicle usage conditions and brake fluid test results.<\/p>\n<p>If the vehicle is often driven in dusty, humid or high-temperature environments, or if it is driven aggressively, the brake system is under extra strain and the replacement interval should be shortened. If symptoms such as a soft brake pedal, longer braking distance or abnormal braking noise appear, check the brake fluid condition immediately and replace it early when needed.<\/p>\n<\/article>\n<\/section>\n<section aria-labelledby=\"system-types-title\" class=\"ag-block\" id=\"system-types\">\n<div class=\"ag-section-header\">\n<span class=\"ag-section-kicker\">System Types<\/span><br \/>\n<span aria-hidden=\"true\" class=\"ag-section-line\"><\/span><\/div>\n<article class=\"ag-richtext\">\n<p class=\"ag-eyebrow\">Choose the method by brake architecture<\/p>\n<h2 class=\"ag-heading\" id=\"system-types-title\">Mainstream Brake System Types<\/h2>\n<\/article>\n<div class=\"ag-card-grid ag-card-grid-2-fixed\">\n<article class=\"ag-guide-card\">\n<span class=\"ag-guide-card__num\">01<\/span><\/p>\n<h3 class=\"ag-guide-card__title\">Traditional Hydraulic Brake System<\/h3>\n<p class=\"ag-guide-card__text\">A widely used system in cars and motorcycles.

As brake systems evolve from mechanical hydraulic systems to complex electronic control systems, brake fluid replacement has also changed. The correct method depends on control structure, module involvement, oil circuit design and whether the system requires a diagnostic tool.<\/p>\n<p>This article mainly introduces two common replacement methods: a brake fluid bleeder method for traditional hydraulic systems and a diagnostic-tool-assisted method for electronic control systems.<\/p>\n<\/article>\n<\/section>\n<section aria-labelledby=\"traditional-method-title\" class=\"ag-block\" id=\"traditional-method\">\n<div class=\"ag-section-header\">\n<span class=\"ag-section-kicker\">Method 01<\/span><br \/>\n<span aria-hidden=\"true\" class=\"ag-section-line\"><\/span><\/div>\n<article class=\"ag-richtext\">\n<p class=\"ag-eyebrow\">Hydraulic and vacuum-assisted systems<\/p>\n<h2 class=\"ag-heading\" id=\"traditional-method-title\">Brake Fluid Replacement Using a Brake Fluid Bleeder<\/h2>\n<p>This method applies to traditional hydraulic brake systems and vacuum-assisted hydraulic brake systems. These systems are suitable for most older gasoline vehicles and the majority of modern gasoline vehicles.<\/p>\n<p>The replacement method for both systems is largely the same and includes two common approaches: gravity fluid replacement and pressure fluid replacement. Gravity fluid replacement uses liquid level difference so fluid flows naturally through the drain port. It is simple, but it may leave old fluid behind. Pressure fluid replacement uses specialized equipment to push or exchange fluid more efficiently and with less residue. The AUTOOL AST series provides the pressure fluid replacement method.<\/p>\n<h3>Main Steps for Fluid Replacement<\/h3>\n<ol>\n<li>Bleed the device first. Make sure the oil reservoir on the vehicle is filled to the maximum level.<\/li>\n<li>Find a suitable adapter and connect it to the vehicle.<\/li>\n<li>Press and hold the start button for 5-6 seconds to build pressure. Once pressure reaches above 0.6 bar, release the button.<\/li>\n<li>Adjust the pressure, usually to 2 bar.<\/li>\n<li>After turning on the machine and adjusting the pressure, loosen the screw on the wheel cylinder or brake caliper.<\/li>\n<li>To judge whether old fluid has been drained, check the layering and color of the fluid in the waste oil bottle. The darker layer is the old fluid.<\/li>\n<li>After replacement is complete, tighten the screw on the wheel cylinder or brake caliper first, then turn off the machine. This sequence is important because incorrect shutdown can allow air into the system.<\/li>\n<\/ol>\n<p>During replacement, check whether there is enough new fluid in the new oil bottle. The device may not stop immediately if the bottle runs out. If the bottle runs out but the device continues feeding fluid, air may enter the system. The low-oil shutdown function is meant to protect against completely draining fluid from the vehicle, but operators should still monitor the bottle throughout the process.<\/p>\n<\/article>\n<\/section>\n<section aria-labelledby=\"electronic-method-title\" class=\"ag-block\" id=\"electronic-method\">\n<div class=\"ag-section-header\">\n<span class=\"ag-section-kicker\">Method 02<\/span><br \/>\n<span aria-hidden=\"true\" class=\"ag-section-line\"><\/span><\/div>\n<article class=\"ag-richtext\">\n<p class=\"ag-eyebrow\">Electronic control systems<\/p>\n<h2 class=\"ag-heading\" id=\"electronic-method-title\">Brake Fluid Replacement With a Diagnostic Tool and Brake Fluid Bleeder<\/h2>\n<p>This method applies to electronic control brake systems, electronic parking brake systems and regenerative braking systems. Because these systems may lack large brake boosters and traditional vacuum structures, technicians cannot always use only traditional bleeding methods. Equipment requirements are more demanding.<\/p>\n<p>It is recommended to use the <a href=\"https:\/\/autoolstore.com\/sv\/product-category\/auto-maintance-tools\/transmission-fluid-exchanger-atf-exchanger\/\">AUTOOL AST series brake fluid bleeder<\/a>, which can steadily output replacement pressure of 2-3 bar. A diagnostic device, such as the LAUNCH X431 diagnostic tool, can be used together with the brake fluid bleeder. This combination supports ABS and EPB system fluid replacement and is suitable for many vehicle models.<\/p>\n<h3>Unlock the Electronic Parking Brake and Enter Maintenance Mode<\/h3>\n<ol>\n<li>Position the vehicle in the workstation, lift it up, and press the brake pedal to manually release the EPB. Once released, the instrument panel indicator for the EPB turns off.<\/li>\n<li>Enter the vehicle infotainment system, go to Settings &#8211; Driver Assistance &#8211; Brake Service &#8211; Release Parking Brake, and select \u201cYes\u201d without pressing the brake pedal.<\/li>\n<li>After these steps, a long \u201czzz\u201d sound may come from the rear parking brake motor, and the dashboard may display a fault light for the EPB system. This indicates the system has fully disengaged. At this point, the engine can be turned off without further action.<\/li>\n<\/ol>\n<h3>Drain the Old Fluid and Replace With New Fluid<\/h3>\n<ol>\n<li>Open the brake fluid reservoir cap and use a pneumatic oil extractor to remove old fluid from the reservoir. Be aware that the reservoir may have two layers, which can make complete draining more difficult. Once old fluid is drained, pour new brake fluid into the reservoir until full.<\/li>\n<li>Connect the brake fluid replacement machine to the container of new brake fluid, usually 2-2.5L of new brake fluid, and tighten the cap on the original vehicle reservoir.<\/li>\n<li>Replace the brake fluid using the traditional hydraulic brake method while the diagnostic tool manages the electronic system requirements.<\/li>\n<\/ol>\n<h3>Reset the System Using a Diagnostic Tool<\/h3>\n<p>After fluid replacement, some vehicles, especially electric vehicles or those equipped with EPB systems, require a diagnostic tool to reset the system.<\/p>\n<ol>\n<li><strong>EPB system reset:<\/strong> enter the EPB function menu and perform \u201cInstall New Brake Pads\u201d or \u201cExit Maintenance Mode.\u201d The system automatically tightens the parking brake calipers. Once successful, the \u201cService Electronic Parking Brake\u201d warning light turns off.<\/li>\n<li><strong>Clear fault codes:<\/strong> return to the main interface, enter \u201cRead Fault Codes,\u201d and clear EPB or ABS error codes generated during replacement. Confirm no warning lights remain on the dashboard.<\/li>\n<li><strong>Exit service state when required:<\/strong> some electric or hybrid vehicles must exit maintenance mode or high-voltage disconnection state before the vehicle can be started.<\/li>\n<\/ol>\n<\/article>\n<\/section>\n<section aria-labelledby=\"final-check-title\" class=\"ag-block\" id=\"final-check\">\n<div class=\"ag-section-header\">\n<span class=\"ag-section-kicker\">Final Check<\/span><br \/>\n<span aria-hidden=\"true\" class=\"ag-section-line\"><\/span><\/div>\n<article class=\"ag-richtext\">\n<p class=\"ag-eyebrow\">Brake test before delivery<\/p>\n<h2 class=\"ag-heading\" id=\"final-check-title\">Final Check and Brake Test<\/h2>\n<p>After replacement is complete, perform the following checks to confirm the brake system functions properly.<\/p>\n<\/article>\n<div class=\"ag-spec-table\">\n<div class=\"ag-table-wrap\">\n<table class=\"ag-table\">\n<thead>\n<tr>\n<th>Check Item<\/th>\n<th>Instruction<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Brake Fluid Level<\/td>\n<td>Open the fluid reservoir cap and ensure the level is between the MIN and MAX markings.<\/td>\n<\/tr>\n<tr>\n<td>Pedal Feel<\/td>\n<td>Press the brake pedal multiple times.

As vehicle technology has evolved from ABS to EPB and brake-by-wire systems, brake fluid replacement is no longer only a simple process of draining old fluid and adding new fluid. It requires the right procedure, suitable tools, diagnostic support when needed and final verification.<\/p>\n<p>For traditional hydraulic and vacuum-assisted systems, a brake fluid bleeder can efficiently complete pressure fluid replacement. For electronic control brake systems, EPB systems and regenerative braking systems, a diagnostic tool and brake fluid bleeder should be used together to enter service mode, release EPB functions, activate modules and clear fault codes.<\/p>\n<p>Contact AUTOOL for expert brake fluid replacement knowledge and tool recommendations.<\/p>\n<\/div>\n<div aria-label=\"Contact AUTOOL for brake fluid replacement support\" class=\"ag-cta\">\n<div>\n<h2 class=\"ag-cta__title\">Need Brake Fluid Replacement Tools?<\/h2>\n<p class=\"ag-cta__text\">Contact AUTOOL to compare brake fluid bleeders, brake fluid testers and diagnostic support tools for your workshop.<\/p>\n<ul class=\"ag-contact-list\">\n<li><strong>WhatsApp:<\/strong> <a href=\"https:\/\/api.whatsapp.com\/send\/?phone=%2B8618926477404&amp;text=DaisySupport\" rel=\"noopener noreferrer\" target=\"_blank\">+86 189 2647 7404<\/a><\/li>\n<li><strong>Email:<\/strong> <a href=\"mailto:shop@autooltech.com\">shop@autooltech.com<\/a><\/li>\n<\/ul>\n<\/div>\n<div class=\"ag-btn-row\">\n<a class=\"ag-button\" href=\"https:\/\/api.whatsapp.com\/send\/?phone=%2B8618926477404&amp;text=DaisySupport\" rel=\"noopener noreferrer\" target=\"_blank\">Online Support<\/a>\n<\/div>\n<\/div>\n<\/section>\n<\/div>\n<aside aria-label=\"Article sidebar\" class=\"ag-sidebar\">\n<section aria-labelledby=\"sidebar-nav-title-57959\" class=\"ag-sidebar-widget is-white\">\n<h2 class=\"ag-sidebar-title\" id=\"sidebar-nav-title-57959\">In This Guide<\/h2>\n<nav aria-label=\"Sidebar table of contents\" class=\"ag-side-nav\">\n<a href=\"#brake-fluid-role\"><span>01<\/span>Brake Fluid Role<\/a><br \/>\n<a href=\"#system-types\"><span>02<\/span>Brake Systems<\/a><br \/>\n<a href=\"#replacement-methods\"><span>03<\/span>Method Overview<\/a><br \/>\n<a href=\"#traditional-method\"><span>04<\/span>Traditional Method<\/a><br \/>\n<a href=\"#electronic-method\"><span>05<\/span>Electronic Method<\/a><br \/>\n<a href=\"#final-check\"><span>06<\/span>Final Check<\/a><br \/>\n<a href=\"#troubleshooting\"><span>07<\/span>Troubleshooting<\/a><br \/>\n<a href=\"#related-products-title-57959\"><span>08<\/span>Related Products<\/a><br \/>\n<a href=\"#related-blogs-title-57959\"><span>09<\/span>Related Blogs<\/a><br \/>\n<\/nav>\n<\/section>\n<section aria-labelledby=\"sidebar-contact-title-57959\" class=\"ag-sidebar-widget\">\n<h2 class=\"ag-sidebar-title\" id=\"sidebar-contact-title-57959\">Ask AUTOOL Support<\/h2>\n<p class=\"ag-sidebar-copy\">Need a brake fluid bleeder, tester or diagnostic workflow for your shop?
