Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear.
2
Check brake pads for thickness and signs of uneven wear.
3
Examine brake calipers for proper function and sticking.
4
Measure rotor thickness with a micrometer to ensure they are within specifications.
5
Inspect wheel bearings and suspension components for wear or damage.

Solution

1. Preparation

Gather tools and materials.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Raise the vehicle using a jack and secure it on jack stands.
Remove lug nuts completely and take off the wheel.

3. Inspect and Replace Rotors

Inspection:
- Use a micrometer to measure rotor thickness; compare to manufacturer specifications.
- Look for signs of warping or scoring on the rotor surface.
Replacement:
- If rotors are warped or below minimum thickness, remove the caliper by unbolting it from the bracket.
- Slide the caliper off the rotor and hang it using a bungee cord to avoid strain on the brake line.
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor, ensuring it is properly seated with any retaining screws tightened to the manufacturer’s torque specifications.

4. Inspect and Replace Brake Pads

Remove the brake pads from the caliper bracket.
Inspect the pads for uneven wear; replace if necessary.
Apply brake grease to the backing of the new pads and install them into the caliper bracket.

5. Reassemble and Test

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications.
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern.
Lower the vehicle and tighten lug nuts to the specified torque.
