Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks in front of the front tires.
Disconnect the negative battery terminal to ensure safety.

2. Remove Rear Wheel

Use a lug wrench to loosen the lug nuts on the rear wheel.
Raise the rear of the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the rear wheel.

3. Inspect Brake Components

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord or hang it from the suspension to avoid straining the brake line.
Check the brake pads for wear; replace if they are below the minimum thickness.
Inspect the rotor for signs of warping, scoring, or excessive wear; replace if necessary.
Examine the caliper for any signs of leakage or sticking.

4. Replace Components (if necessary)

If brake pads are worn, replace them with new ones. Be sure to lubricate the backing of the pads with anti-squeal lubricant.
If the rotor is damaged, remove it by unscrewing the retaining screws (if applicable) and replace it with a new rotor.
If calipers are sticking, replace them with new calipers. Ensure that the sliding pins are properly lubricated.

5. Bleed Brake System

Reconnect the caliper and tighten the caliper bolts to the manufacturer’s specified torque.
Refill the brake fluid reservoir with the appropriate type of brake fluid.
Bleed the brake system to remove air using a brake bleeder kit:
1. Have an assistant pump the brake pedal several times and hold it down.
2. Open the bleeder screw on the caliper and allow fluid to flow out until no air bubbles are visible.
3. Close the bleeder screw and repeat for each rear brake caliper.

6. Reassemble and Test

Reinstall the rear wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Reconnect the negative battery terminal.
Start the vehicle and test the brakes at low speed to ensure they function correctly.
