Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Gather safety equipment such as gloves and safety glasses.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Brake cleaner
Caliper tool or thickness gauge
Screwdriver (if applicable for caliper removal)

2. Lift the Vehicle

Use the jack to lift the rear of the vehicle.
Secure with jack stands to ensure safety.

3. Remove the Wheel

Use the lug wrench to loosen and remove the lug nuts from the rear wheel.
Carefully take off the wheel and set it aside.

4. Inspect and Replace Brake Pads

Remove the caliper bolts using the appropriate socket.
Carefully lift the caliper off the rotor without disconnecting the brake line; support it with a bungee cord or similar device.
Remove the old brake pads from the caliper bracket.
Inspect the brake pads for wear; replace if they are below the minimum thickness (usually around 3mm).
If replacing, install new brake pads by sliding them into the caliper bracket.

5. Clean and Inspect Rotor

Use brake cleaner to clean the rotor surface.
Inspect the rotor for scoring or cracks; replace if necessary.
If the rotor is within specifications, re-install it.

6. Reassemble the Braking System

Compress the caliper piston using a caliper tool to accommodate the new pads.
Place the caliper back onto the rotor and secure it with bolts, tightening to the manufacturer’s specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground by removing jack stands.
Torque the lug nuts to the manufacturer’s specifications.
