Solution

1. Preparation

Gather all necessary tools and parts.
Ensure vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle.
Secure the vehicle with jack stands.

3. Remove Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Remove the wheel to access the brake assembly.

4. Remove Brake Caliper

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor and hang it using a bungee cord to avoid stressing the brake line.

5. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Inspect the caliper bracket and slide pins for wear and lubrication; clean if necessary.
Install new brake pads into the caliper bracket, ensuring they are seated properly.

6. Inspect and Replace Brake Rotor (if necessary)

If rotors are damaged or below minimum thickness, remove the rotor by unscrewing the retaining screws (if applicable).
Install new rotor, ensuring it is seated properly on the hub.
Torque rotor screws to manufacturer specifications (usually around 10-15 ft-lbs).

7. Reassemble Brake Components

Reinstall the brake caliper over the new brake pads and rotor.
Secure with the caliper mounting bolts, torquing to manufacturer specifications (typically 20-30 ft-lbs).
Reinstall the wheel and torque the lug nuts in a crisscross pattern to specification (usually 76-83 ft-lbs).

8. Lower the Vehicle

Carefully lower the vehicle to the ground using the hydraulic jack and remove jack stands.

9. Final Check

Pump the brake pedal several times to ensure proper brake pad seating.
Check brake fluid level and top off if necessary.
