Read further to learn how to replace the rear disc brakes in your Sentra because you may be surprised to learn that it's not as difficult as you may think.
Lift the rear of the vehicle off the ground using a car jack. Balance the vehicle on all sides to prevent it from tipping. Keep children and animals out of the vicinity while replacing the rear disc brakes on your Sentra.
Disconnect the parking brake cable bracket bolt. Remove the pin bolts and take off the body of the caliper. Slide out the pad springs, brake pads and shims.
