Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Safety: Disconnect the battery to prevent accidental electrical shorts.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on the affected brake pads.
Secure the vehicle with jack stands to ensure stability.

3. Remove Wheel and Brake Components

Remove the wheel using a socket set.
Unbolt the brake caliper using the appropriate socket size.
Carefully slide the caliper off the rotor, taking care not to damage the brake line.
Remove the brake pads from the caliper bracket.

4. Inspect and Clean Components

Inspect the brake pads, calipers, and rotors for any signs of damage or wear.
Clean the caliper slide pins and brackets with a brake cleaner.
Apply brake grease to the caliper slide pins and any contact points.

5. Replace or Adjust Components

If calipers are sticking, consider replacing them.
Replace any worn brake pads with high-quality replacements.
If rotors are warped, replace them with new rotors.
If necessary, adjust the suspension or steering components to correct alignment issues.
