How to Adjust the Brake Oil Pressure of the Electronic Anti-lock Control Device?
2 Answers
There is a long screw rod above the brake, with both ends located above the two brake shoes, and one end is also connected to the pusher through some lever mechanisms. Disconnect the power to the motor that needs braking, remove the wiring in the motor junction box, and only supply power to the pusher motor. At this time, adjust the nut at one end of the aforementioned long screw rod so that the brake can be completely separated. When the pusher motor is powered off, the mechanism can retract to make the brake shoes grip tightly.
As a seasoned car repair veteran, I often encounter similar issues. The brake fluid pressure in the electronic anti-lock braking system is not manually adjustable; it's entirely controlled by the Electronic Control Unit (ECU) which detects potential wheel lock-up via wheel speed sensors. If the ECU identifies a high risk, it commands the pump and valves to rapidly release or apply hydraulic pressure—all automatically—to prevent skidding and maintain stability. If you notice soft brakes or an illuminated ABS light, never attempt to adjust the pressure yourself—this could lead to system failure or accidents. Common problems usually involve dirty sensors or aging pumps, requiring professional diagnostic tools for repair. I recommend regular checks of brake fluid and ABS components to ensure system responsiveness and reliability. This design prioritizes maximum safety during emergency braking, and tampering with it yourself will only backfire.
