Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle.
Secure the vehicle with jack stands for safety.
Remove the front wheels using a lug wrench.

3. Inspect and Replace Brake Components

a. Inspect Brake Rotors

Visually check for scoring, grooves, or warping.
If warped, remove the caliper by unscrewing the caliper bolts and hang it using a bungee cord.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off.
Replace with new rotors if necessary. Ensure the new rotors are clean and free from oil.

b. Inspect Brake Pads

Remove the brake pads from the caliper bracket.
Check for uneven wear; replace if worn below specifications (usually 3mm).
Install new brake pads, ensuring they are properly seated.

4. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (typically 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Torque Wheels

Carefully lower the vehicle off the jack stands.
Use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque (usually 80-100 ft-lbs).
