How To Change Rear Brake Pads

To ensure safety and efficiency when it comes to braking, you have to maintain the ideal friction pad depth. You could do this by proper maintenance and replacement of the worn our brake pads with new ones. If it less than one-fourth inch, you should think of replacing a brake pad soon, but if it is just less than one-eighth inch, do it as soon as possible because it will cause damage to your rotor. Compared to rear drum brakes, rear disc brakes are more consistent in terms of braking power, require less maintenance when it comes to cleaning and adjusting, and are relatively easier to replace. Rear disc brakes provide lesser braking capacity, so the brake pads are thinner compared to the front brake pads. Replacing the rear brake pads follows almost the same procedure as what you do with the front brake pads.

  1. Remove the back tires. Lift the rear end of the vehicle using jack stands, or you could also lift the entire vehicle if possible. Remove the hub caps, and using an impact gun and socket, remove the lug nuts and then the wheels.
  2. Remove the caliper bolts. Find the caliper bolts and remove them using a hand ratchet and a socket. If the bolts are corroded, you could apply heat to them using a propane torch until they loosen up. Refer to the car's manual to know what type of vehicle you are working on. Some vehicles have pivoting calipers. With these types of vehicles, you only need to remove the lower bolt. The caliper pivots to remove the upper bolts.
  3. Compress the caliper piston inward, remove the old hardware or rattle clips, remove the old pads and then replace them with new ones. You may use a C-clamp to compress the piston inward. Apply a certain amount of pressure until it is settled fully inside the caliper piston bore. Remove the brake pads. Check the caliper slides and its rubber boots for damages. Replace it if possible. Also replace the old rattle clips, put grease or lubricant onto the caliper bridge, and then install the new brake pads.
  4. Replace the caliper and its bolts; replace the wheel and its lug nuts. Put the caliper back carefully and replace the caliper bolts. Then put the wheel back into place, and use an impact gun and torque socket to replace all the lug nuts. Make sure that they are secured tightly. Repeat procedures 1-3 for the other rear wheel.
  5. Pump the foot brake pedal. Doing this will set the brake pads onto the rotor and will apply pressure to the caliper pistons.
