Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery (negative terminal) to avoid any electrical issues during the repair.

2. Remove Wheel

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the lug nuts using a socket, then take off the wheel to access the brake assembly.

3. Inspect and Remove Brake Components

Inspect Brake Pads:
- Check the thickness of the brake pads; if less than 3mm, replace them.
Remove Caliper:
- Unbolt the caliper mounting bolts using the appropriate socket.
- Carefully slide the caliper off the rotor; support it with a bungee cord to avoid straining the brake line.
Remove Brake Pads:
- Slide the old brake pads out of the caliper bracket.
Inspect Rotor:
- Check for scoring or warping. If damaged, remove the rotor by unbolting it from the hub.

4. Install New Components

Install New Brake Pads:
- Apply brake grease to the back of the new pads (if applicable) to reduce noise.
- Slide the new brake pads into the caliper bracket.
Reinstall Caliper:
- Compress the caliper piston using a caliper tool or C-clamp to allow for the new pads.
- Position the caliper back over the pads and bolt it in place securely.
Reinstall Rotor:
- If replaced, install the new rotor and secure it with bolts.

5. Reassemble Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the manufacturer's specifications.

6. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper brake engagement.
