2
Check brake rotors for scoring or uneven wear.
3

Solution

1. Preparation

Gather all necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on which axle is affected).
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Using a lug wrench, loosen and remove the wheel lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspection:
- Remove the brake caliper by unbolting the caliper mounting bolts (usually 12-19mm).
- Slide the caliper off the rotor and hang it using a bungee cord (do not let it dangle by the brake line).
- Remove the old brake pads by sliding them out of the caliper bracket.
Replacement:
- Install new brake pads by aligning them in the caliper bracket.
- Ensure the pad with the wear indicator is installed correctly (if applicable).

5. Inspect and Resurface or Replace Rotors

Check the rotor surface for grooves or scoring. If damaged, either resurface or replace.
If resurfacing, ensure the rotor thickness meets manufacturer specifications.
If replacing, unbolt the rotor from the hub and install the new rotor, tightening the bolts to the recommended torque (typically 70-90 ft-lbs).

6. Reassemble and Test

Reinstall the brake caliper, tightening the bolts to the recommended torque (usually 20-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to the specified torque (typically 80-100 ft-lbs).
Lower the vehicle and check the brake fluid level, adding fluid if necessary.
