Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully lift the caliper off the rotor and support it with a bungee cord (do not hang by the brake line).
Remove the old brake pads and inspect the caliper bracket.
Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped, remove them by unscrewing the retaining screws (if applicable) and sliding them off the hub.
Clean the hub surface before installing new rotors.
Install new rotors and secure them as per manufacturer specifications.

5. Reassemble Braking System

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer’s torque specifications.
Reinstall the wheel and lug nuts, tightening in a star pattern.

6. Final Checks

Lower the vehicle and remove jack stands.
Pump the brake pedal several times to ensure proper pressure is restored.
Check brake fluid level and add if necessary.
