Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during repairs.

2. Raise the Vehicle

Use a jack to lift the rear of the vehicle and secure it on jack stands.
Remove the rear wheels using a socket set.

3. Remove Brake Components

Brake Caliper Removal
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it using a bungee cord to avoid strain on the brake line.
Brake Pad Removal
- Remove the old brake pads from the caliper bracket.
Rotor Removal
- If necessary, remove the rotor by unscrewing any retaining screws and sliding it off the hub.

4. Inspection and Replacement

Inspect Components
- Check the brake pads for excessive wear; replace if less than 3mm thick.
- Inspect the rotors for grooves or warping; replace if damaged beyond resurfacing.
Install New Components
- Install new brake pads into the caliper bracket.
- If needed, replace the rotor with a new or resurfaced unit. Ensure it is properly seated on the hub.

5. Reassemble Brake Components

Reattach Calipers
- Apply anti-squeal lubricant to the back of the new brake pads.
- Slide the caliper back over the new pads and rotor and secure it with the caliper bolts. Torque bolts to manufacturer specifications (typically 20-30 ft-lbs).

6. Final Steps

Reinstall the rear wheels and lower the vehicle.
Reconnect the battery.
