Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on which brakes are being serviced).
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the lug nuts and take off the wheel for access to the brake components.

4. Inspect and Replace Brake Pads

Inspect Brake Pads
- Check for thickness; if less than 3mm, replace pads.
Remove Old Brake Pads
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang on the brake line).
Install New Brake Pads
- Apply anti-squeal grease to the back of the new pads.
- Slide the new pads into the caliper bracket.

5. Inspect and Resurface or Replace Brake Rotors

Inspect Rotors
- Check for any scoring or warping; if warped, resurface or replace.
Replace Rotors (if necessary)
- Remove the caliper bracket to access the rotors.
- Remove the rotor by unscrewing the retaining screws if present.
- Install new rotors, ensuring they are clean and free from oil.

6. Reassemble and Test

Reattach the caliper and secure it with the bolts, torquing to manufacturer specifications (typically 20-25 ft-lbs).
Reinstall the wheel and lug nuts, tightening to the correct torque (usually 76-86 ft-lbs).
Lower the vehicle and pump the brake pedal to seat the pads.
