How To Reset Brake Proportioning Valve

To reset or adjust a brake proportioning valve, you typically need to follow these general steps, but be sure to consult your vehicle's manual for specific guidance:

1. How To Reset Brake Proportioning Valve: Locate the Proportioning Valve: It is usually located along the brake line, near the master cylinder or under the vehicle, depending on the system design.

2. Inspect for Adjustment Mechanisms: Some proportioning valves have a manual adjustment screw, while others may be automatic. If it’s an automatic valve, resetting may involve simply reestablishing the proper fluid pressure by bleeding the brake system.

3. Manual Adjustment: If your valve has an adjustment screw, turn it to the recommended position. Typically, turning it clockwise will reduce rear brake pressure, while counterclockwise will increase it.

4. Bleed the Brakes: After adjusting the proportioning valve, it’s important to bleed the brakes to remove air from the brake lines and ensure proper fluid pressure.

5. Test the System: After resetting, check the braking performance. Test-drive the vehicle at low speeds, ensuring that the brakes engage evenly without uneven braking or skidding.

If you’re not comfortable with adjusting brake components, it’s best to have a professional mechanic perform the task to ensure safety and accuracy.

Additional Tips
