Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Rear Wheels

Using a lug wrench, loosen the lug nuts on both rear wheels.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the rear wheels.

3. Inspect and Replace Brake Pads and Rotors

Remove the caliper bolts using a socket wrench and carefully lift the caliper off the rotor.
Support the caliper using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the rotors for scoring or warping; if damaged, proceed to replace them.
Install new brake pads into the caliper bracket, ensuring they are properly seated.
If replacing rotors, remove the old rotor and install the new rotor, securing it with the appropriate hardware.

4. Reassemble Caliper

Compress the caliper piston using a brake caliper tool to create space for the new pads.
Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque settings (typically around 25-30 ft-lbs).

5. Bleed the Brake System

Reconnect the brake line if it was disconnected.
Bleed the rear brakes using a brake bleeder kit, starting with the wheel farthest from the master cylinder.
Check the brake fluid level in the master cylinder and top off as necessary.

6. Reinstall Wheels and Final Checks

Reinstall the rear wheels and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque (usually around 80-100 ft-lbs).
Reconnect the battery and verify that the brake warning light is off.
