Solution

1. Preparation

Gather necessary tools and parts: Jack stands, lug wrench, brake cleaner, new brake pads, and possibly new calipers.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Raise Vehicle

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels using a lug wrench.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the appropriate socket.
Gently slide the caliper off the brake rotor and support it without straining the brake line.
Remove old brake pads from the caliper bracket and inspect the rotor for wear.
Clean the caliper bracket and rotor with brake cleaner to remove dust and debris.
Install new brake pads, ensuring proper orientation and fit in the caliper bracket.

4. Inspect and Replace Calipers (if necessary)

If calipers are found to be sticking, remove them from the bracket.
Detach the brake line from the caliper using a wrench, and replace with a new caliper if it's defective.
Install the new caliper, ensuring to torque the brake line fitting to the manufacturer's specifications.

5. Reassemble

Reinstall the caliper over the new brake pads and secure with caliper bolts, torquing to the specified value.
Replace the rear wheels and lower the vehicle back to the ground.

6. Final Checks

Pump the brake pedal to ensure proper pad seating and brake fluid pressure.
Test the parking brake for proper adjustment and release.
