AUTOOL PT660 · Dual Brake Pressure Tester
Compare Two Brake Pressure Points at Once
Compare hydraulic pressure at two brake positions during the same test condition with this dual-channel brake pressure gauge. PT660 measures both channels across 0–210 bar, helping reveal front/rear or left/right imbalance without moving one gauge between points. Hold and ambient-zero controls support repeatable setup, while the backlit display keeps both readings visible.
- 0–210 Bar Brake Range
- Dual-Channel Brake Comparison
- Stated ±1% FS Accuracy
- Hold Both Channel Readings
- Ambient-Zero Both Channels

主要特色
Synchronous Left/Right Pressure Inputs
Dual-Channel Brake Pressure Detection
Detect two brake pressure channels through the L/R input slots, making it easier to compare front / rear or left / right brake pressure behavior.
Brake Pressure Balance Comparison
Supports simultaneous pressure comparison between two brake calipers, helping technicians capture pressure differences and observe brake-system pressure imbalance.
Stated ±1% FS Accuracy
Built-in high-precision sensor provides measurement accuracy up to ±1%FS for brake system pressure checking.
測量範圍廣
PT660 supports a 0–210 bar measurement range with 0.1 resolution and an operating temperature range of -10°C to +60°C, helping cover common internal brake-system pressure checks.
Smart 3-Inch Backlit Display
The 3-inch backlit digital display shows pressure data clearly in bright or dim workshop environments without complicated menu browsing.
One-Click Locking And Zeroing
Supports one-click locking and zeroing, zeroing to ambient pressure, and visualized data display for more efficient brake pressure measurement.
3年保固支持
主機:三年保固。標準配件:一年保固。保固政策。
服務工作流程
Connect Both Sides and Compare Like Conditions
Connect L/R Pressure Input
Connect the pressure input cable to the L/R slot according to the channel you need to test or compare.
Zero Before Testing
With both channels safely open to ambient pressure and unloaded, perform the user zero/tare step before connecting and pressurizing the brake system. This is a setup zero, not a traceable calibration.
Install Adapter
Connect the model-specific adapter to the measurement probe and confirm the connection is secure.
Select Unit And Wheel Direction
Select the required unit, such as psi, Bar, or kg/cm², and choose the wheel direction before testing.
開始測量
Press the Measurement button to start brake pressure measurement and monitor the pressure values on the display.
Review And Switch Units
After measurement is complete, review the results, compare pressure values, and switch units when needed.
安全使用
Control Hydraulic Pressure and Bleeding State
Use the Result for the Next Check
Compare both channels under the same pedal condition with brake-fluid-rated hoses and adapters. Investigate the relevant hydraulic circuit if an imbalance appears.

Pressure Connection and Reading Questions
Do I Need To Zero The PT660 Before Testing?
Zero the PT660 to ambient pressure before every test to improve measurement reliability.
What Is The Measurement Range Of PT660?
PT660 supports a measurement range of 0-210Bar. Always pay attention to the measuring range before and during testing.
What Units Does PT660 Support?
PT660 supports psi, Bar, and kg/cm². The resolution is 0.1psi, 0.1Bar, and 0.1kg/cm².
Can PT660 Compare Two Brake Calipers?
Yes. PT660 supports dual-channel pressure measurement and can be used to compare the pressure of two brake calipers or two brake pressure positions through the L/R pressure input channels.
What Batteries Does PT660 Use?
PT660 uses 4 × 1.5V AAA batteries. Check battery level and battery condition before testing.
What Happens If The Measuring Range Is Exceeded?
If the measuring range is exceeded, the result may display the maximum or minimum value. Stop testing, confirm the pressure condition, and make sure the test is within the supported range.
What Should I Check Before Use?
Before use, check the batteries, pressure input cable, hoses, adapters, and all connections. Wear safety goggles and protective gloves when working near brake fluid or system fluid.
