How does a Honda proportioning valve work?
The proportioning valve is designed to allow a quicker pedal response for drum brake vehicles by allowing the rear brakes to get the brunt of the fluid first to allow for the pads to make contact. As soon as there is resistance then the pressure through out the system equalizes immediately.
What happens when a metering valve goes bad?
Since the proportioning valve decreases the pressure sent to the rear brakes, the main symptom the valve is going bad is the rear wheels locking up when the brakes are applied. Furthermore, the wheels will lock up more easily on wet surfaces. The rear brakes may feel touchy when applied even gently.
How do you reset a prop valve?
How to Reset a Brake Proportioning Valve
- Locate the brake proportioning valve near the rear brake line. It will have one or two buttons located on it.
- Push the reset button located on the valve with your fingers, which will reset it so the valve is working properly again. Inspect the brake pressure.

How do you fix a stuck proportioning valve?
Place a flare nut wrench on the rear cap nut to the rear brake line. Instruct your assistant to hold the brake firmly, while you open the cap nut with the wrench. If the brake pedal does not move downward, have your assistant stomp on the brake pedal with medium to hard pressure, and hold it down firmly.
Do you need to bleed a proportioning valve?
The proportioning valve doesn’t have any way to bleed air, so you will have to bleed the front and rear brake lines in order to remove any air trapped in the valve. Park your car on a flat surface and set the emergency brake, to prevent your car from rolling while you are working under it.
Will a bad proportioning valve cause a hard brake pedal?
Because the brake fluid can’t be compressed, the pedal becomes rock hard. You still can generate moderate pressure on the “good” side of the valve therefore allowing the car to be driven in a limp home scenario.
