Solution

1. Preparation

Gather all tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Rear Wheel

Tools Required: Socket set, jack, jack stands.
Lift the rear of the vehicle using a jack and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the rear wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the brake rotor and support it with a bungee cord to avoid straining the brake line.
Inspect the brake pads; if worn beyond specifications (typically 3mm), replace them.
Sub-steps:
- Remove the old pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease to the contact points.
- Install new brake pads, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

Check the brake rotors for wear; replace if they are below the minimum thickness specification or if there is visible scoring.
Sub-steps:
- Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
- Install the new rotor and secure it with retaining screws.

5. Reassemble Brake Components

Slide the caliper back over the new brake pads and rotor.
Reinstall and torque caliper bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).
Reattach the rear wheel and hand-tighten the lug nuts.

6. Refill Brake Fluid and Bleed System

Check the brake fluid level and add fluid if necessary.
Bleed the rear brake lines to remove any air using a brake bleeder kit. Start with the side farthest from the master cylinder and work towards the closest.

7. Final Checks

Reconnect the negative battery terminal.
Lower the vehicle and perform a test of the brake pedal feel.
