Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and securely lift it using a jack and jack stands.
Disconnect the battery to prevent electrical shorts.

2. Remove Wheel and Brake Components

Tools Required: Socket set, torque wrench, brake cleaner.
Remove the wheel using a socket wrench.
Detach the brake caliper by removing the caliper bolts. Support the caliper with a bungee cord to avoid strain on the brake line.
Remove the brake pads from the caliper bracket.

3. Inspect and Clean Components

Tools Required: Brake cleaner, wire brush.
Clean the caliper bracket and pistons using brake cleaner and a wire brush.
Inspect the caliper slides and ensure they are free of dust and debris; lubricate with high-temperature brake grease if necessary.
Check brake rotor for wear; if warped or excessively worn, proceed to replace.

4. Replace Brake Pads and Reassemble

Parts Required: New brake pads, possibly new rotors if needed.
Install new brake pads into the caliper bracket ensuring the correct orientation.
Reattach the brake caliper over the new pads and tighten the caliper bolts to the manufacturer’s specified torque.
Reinstall the wheel and lower the vehicle.

5. Brake System Bleed (if necessary)

Tools Required: Brake bleeder kit, brake fluid.
If any brake fluid was lost during repair, bleed the brake system to remove air bubbles, starting from the farthest wheel from the master cylinder.
