Funzionalità principali
Normal and Expert Brake Fluid Modes
Water-Content Screening
The flexible reservoir probe screens brake-fluid water content in the selected supported mode. It does not generate or measure hydraulic brake pressure.
Multiple Brake Fluid Support
Normal mode supports DOT3, DOT4, and DOT5.1 brake fluid, making AS502 suitable for common vehicle brake fluid checks.
Normal And Expert Modes
Switch between standard brake-fluid type testing and expert mode for selected DOT4 brands when more targeted fluid selection is needed.
260mm Flexible Probe
The 260mm gooseneck probe helps reach the brake fluid reservoir more easily during vehicle maintenance.
304 Stainless Steel Outer Hose
The probe hose outer layer uses 304 stainless steel for oil resistance, oxidation resistance, and corrosion resistance.
2.8-inch Backlit Display
The 2.8-inch LCD backlit display makes the result easier to read in bright or low-light working conditions.
Single-Handed Control
The silicone grip and handheld control layout support single-handed brake fluid testing.
Alimentazione a batterie AAA
The tester uses 6V power from 4 × 1.5V AAA batteries. Install batteries with the correct polarity before operation.
Water Content And Status
The screen displays brake fluid water content together with OK, warning and suggested replacement indicators.
5-Minute Auto Power-Off
The tester automatically powers off after 5 minutes without operation to conserve battery power.

Uso sicuro
Separate Fluid Fit from Service Verdict
Brake Fluid Water Test
AS502 is designed to test the water content percentage in brake fluid. It is not an engine oil, transmission fluid, or power steering fluid tester.
Use Supported Fluids Only
Use AS502 with supported brake fluid types. Normal mode is for DOT3, DOT4, and DOT5.1 brake fluid; expert mode is for selected DOT4 brands.
Install 4 AAA Batteries
The tester uses 6V power from 4 × 1.5V AAA batteries. Install batteries with the correct polarity before operation.
Routine Check Suggestion
For routine maintenance, checking brake fluid around every 40,000 km is recommended, depending on vehicle condition and service requirements.
Clean The Probe
Wipe the probe clean before each measurement and clean it after use to avoid fluid residue affecting later tests.
Conservare in luogo asciutto
If the tester will not be used for a long time, remove all batteries and store the unit in a dry place at normal room temperature.
Use the Moisture Screening Result
Select the exact brake-fluid mode, clean the probe between samples and use the displayed moisture/grade value for quick fluid screening. It is not a standardized wet boiling-point result.

Domande relative a fluidi, metodo e risultati
Cosa fa AUTOOL Test AS502?
AUTOOL AS502 tests the water content percentage in brake fluid. It helps users evaluate brake fluid condition and decide whether maintenance or replacement may be needed.
Quali tipi di liquido freni sono supportati dallo standard AS502?
Normal mode supports DOT3, DOT4, and DOT5.1 brake fluid. Expert mode supports selected DOT4 brands, including MOTUL, ATE, FERODO, MOBIL, BREMBO, TRW, BOSCH, CASTROL, TOTAL, VALEO, FUCHS, and TEXTAR.
What Batteries Does AS502 Use?
AS502 uses 6V power from 4 × 1.5V AAA batteries. Open the rear battery cover, insert the batteries with the correct polarity, and close the cover securely before use.
How Do I Use AS502 For A Brake Fluid Test?
Clean the probe, open the brake fluid reservoir cap, select the correct brake fluid type or expert-mode brand, immerse the probe into the brake fluid, then press the test button. The screen will display the water content percentage and status indication.
How Should I Read The Test Result?
The percentage value shows the water content in the brake fluid. OK indicates the water content is good, ! indicates a warning, and × indicates replacement is suggested. The manual describes 0%-2% as a pass range, 2%-3% as a warning range, and above 3% as a replacement range.
How Often Should Brake Fluid Be Tested?
For routine maintenance, checking brake fluid around every 40,000 km is recommended. Actual testing frequency should also follow the vehicle condition, driving environment, and service requirements.
How Should I Maintain The Probe After Use?
Wipe the probe clean after use and avoid leaving stains or brake fluid residue on the probe. If the tester will not be used for a long time, remove all batteries and store it in a dry place at normal room temperature.
What Is The Difference Between AS502 And Other AUTOOL Fluid Testers?
AS502 is for brake fluid water-content testing with a 2.8-inch display, 6V power, and normal/expert modes. AS503 is for engine oil quality, AS505 is for transmission fluid, AS506 is for brake fluid boiling point, and AS507 is for power steering fluid. Choose by the fluid type and test principle you need.

The AS502 perfectly meets my needs.
The AS502 perfectly meets my needs. My car has recently been experiencing issues with insufficient brake pressure and soft brakes. After searching online, everyone gave me advice on whether I need to replace the brake fluid. This device tests the water content in the brake fluid to determine whether my car’s brake fluid needs to be replaced. It’s easy to operate and suitable for novices.

This brake fluid tester determines whether the car’s brake head needs to be replaced by detecting the water content of the brake fluid. When used with a brake fluid replacement machine, the number of times the brake fluid needs to be replaced is much faster.
