Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Lift the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Take off the wheel to expose the brake assembly.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the thickness of the brake pads. If they are below 3mm, replace them.
Remove Old Brake Pads:
- Use a socket set to remove the caliper bolts.
- Carefully slide the caliper off the rotor and support it to avoid strain on the brake line.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads.
- Slide the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotor Condition: Look for grooves or warping. If damaged, remove the rotor.
Remove Rotor: Unscrew the rotor retaining screws if applicable and slide the rotor off the hub.
Install New Rotor: Place the new rotor onto the hub and secure it with screws.

5. Reassemble Braking System

Reinstall the caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer's specifications (usually around 25-35 ft-lbs).
Reattach the wheel, securing the lug nuts in a crisscross pattern to ensure even tightening.

6. Final Checks

Lower the vehicle and pump the brake pedal to ensure proper pad seating.
Check brake fluid level and top off if necessary.
