How to Adjust the Rear Disc Brakes

by Katebo

Rear disc brakes have replaced drum braking systems because they provide faster braking response and they outlast drum brakes. Also, disc brakes are self-adjusting unlike the old drum brakes that had to be manually adjusted. But even though cars with rear disc brakes are self-adjusting, the brakes still benefit from an adjustment periodically, especially right after you've had the brake pads replaced. This will help the brake pads stick to the rotors correctly. You can also adjust your brakes if they feel mushy and you want them firmer.

Step 1

Start the car and put it in reverse.

Step 2

Accelerate the car slowly then press down on the brakes gently.

Step 3

Repeat Step 2 four times or until the brake pedal is higher and feels firm to your foot.

Step 4

Drive the car forward and bring it up to a speed of 40 miles per hour. Slow down the car by pressing on the brakes until the car is going about 10 MPH.

Step 5

Repeat Step 4 three more times. Do not bring the car to a complete stop during this process.

Stop the vehicle and put it in park.

Tip

  • Ideally, you should perform a brake inspection about every second oil change to check and see if the brake pads are wearing evenly. Remove the wheel and measure the thickness of the pads. They should be at least 3 mm thick. If they are thinner than 3 mm, you need to replace the brake pads.
