Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheel

Loosen lug nuts with a socket and ratchet while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect Brake Components

Examine the brake pads for thickness; they should have at least 1/8 inch of material.
Check the brake rotors for wear; they should be smooth and free of deep grooves.
If pads or rotors are worn, proceed to the next step for replacement.

4. Replace Brake Pads and Rotors

Remove Old Brake Pads:
- Remove the caliper bolts using a socket.
- Slide the caliper off the rotor and hang it with a bungee cord to avoid strain on the brake line.
- Remove the old brake pads from the caliper bracket.
Replace Rotors (if necessary):
- Remove the rotor by unscrewing any retaining screws.
- Clean the hub surface with brake cleaner before installing the new rotor.
- Install the new rotor, securing it with retaining screws if applicable.
Install New Brake Pads:
- Place the new pads into the caliper bracket.
- Apply brake grease to the backing of the pads to prevent squeaking.
- Reinstall the caliper over the new pads and secure it with bolts.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts to the manufacturer’s torque specification.
Pump the brake pedal several times to ensure proper pad seating.
