Key features
- Self adjuster lever for drum brakes
- For 10 inch brakes
- Passenger side, rear right position
- Direct fit
Adjuster lever service
The self adjuster lever moves the adjuster wheel when the shoes wear, keeping the shoes close to the drum. When the lever binds or fails to engage, the shoes drift away from the drum and pedal travel grows. A worn lever can also let the adjuster slip, so the wear shows up as a high or spongy pedal.
Replacing the lever is usually done with the drum off, and the adjuster and spring should be checked at the same time. Confirm that the lever moves freely on its pivot and that the spring has its full tension. Because the passenger and driver levers are separate parts, the failed side is the one to replace, but the opposite lever should be inspected for matching wear.
- Pedal travel that keeps growing
- Adjuster that does not ratchet
- Stiff or seized lever pivot
- Worn drum contact on one side
