Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator gauge.
2
Check brake pads for thickness and signs of uneven wear.
3

4
Inspect wheel bearings for play or roughness during rotation.

Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a flat surface, and the engine is off.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which brakes are affected.
Secure with jack stands for safety.

3. Remove Wheels

Use the lug wrench to remove the lug nuts and take off the wheels to access the brake components.

4. Inspect and Replace Brake Rotors (if warped)

Inspect: Mount the dial indicator on the brake rotor surface to measure runout.
Replace: If warping exceeds manufacturer specifications, remove the caliper (using a socket and ratchet) and rotor (remove any retaining screws or clips). Install new rotors, ensuring they are properly seated. Torque to manufacturer's specifications.

5. Inspect and Replace Brake Pads (if worn)

Remove the brake caliper by unbolting it from the bracket.
Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove old brake pads and inspect the backing plate for damage. Install new pads, ensuring they fit snugly.

6. Reassemble Components

Reinstall the brake caliper over the new pads and rotor.
Tighten bolts to the manufacturer's torque specifications.
Reattach wheels and hand-tighten lug nuts.

7. Lower Vehicle and Test

Carefully lower the vehicle back to the ground.
Tighten lug nuts to the specified torque with the vehicle on the ground for stability.
