Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Use wheel chocks for added safety.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
C-clamp or brake caliper tool
Safety goggles and gloves

2. Remove the Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the rear wheel to access the brake assembly.

3. Inspect and Remove Brake Components

Locate the brake caliper and remove the caliper mounting bolts using a socket.
Carefully slide the caliper off the rotor. Support the caliper using a bungee cord or hanging it to avoid stress on the brake line.
Inspect the brake pads for wear; if they are below the minimum thickness, proceed to replace them.
If necessary, remove the rotor by unscrewing the rotor retaining screws (if equipped) and sliding it off the hub.

4. Install New Brake Pads and Rotor

Clean the rotor surface with brake cleaner to remove any contaminants.
If replacing the rotor, install the new rotor onto the hub, tightening any retaining screws.
Insert new brake pads into the caliper bracket.
Use a C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing to accommodate the new pads.
Reinstall the caliper over the new pads and secure it with the mounting bolts. Torque to manufacturer specifications.

5. Reinstall the Wheel

Place the wheel back onto the hub, hand-tightening the lug nuts initially.
Lower the vehicle off the jack stands and onto the ground.
Using a torque wrench, tighten the lug nuts to the specified torque according to the manufacturer’s specifications.
