Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a C-clamp or brake caliper tool.
Safety Warnings: Ensure the vehicle is on a level surface and securely supported by jack stands. Always wear safety glasses.

2. Remove Wheel

Loosen the lug nuts on the affected wheel slightly while the vehicle is on the ground.
Raise the vehicle using a jack and support it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Caliper

Locate the caliper mounting bolts and remove them using the appropriate socket.
Carefully slide the caliper off the rotor without stretching the brake line.
Secure the caliper to the suspension using a bungee cord or similar to avoid stress on the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the brake pad backing for wear indicators and replace if necessary.
Clean the caliper bracket and apply brake grease to the contact points of the new pads.
Install the new brake pads into the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

If the rotors are worn or damaged, remove them from the hub by removing the retaining screws or bolts.
Clean the hub surface before installing new rotors.
Install new rotors and secure them with the appropriate bolts or screws, ensuring they are torqued to manufacturer specifications.

6. Reassemble Brake Components

Reinstall the brake caliper over the new pads and rotor.
Tighten the caliper mounting bolts to the manufacturer’s torque specifications.

7. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground and then tighten the lug nuts to the specified torque.
