Diagnostic Steps

1
Inspect the brake rotors for warping using a dial indicator.
2
Check brake pad thickness to ensure they are not worn beyond specifications.
3
Examine the brake calipers for proper operation and any signs of sticking.
4
Inspect suspension components (e.g., control arms, bushings) for wear or damage.
5
Verify wheel lug nut torque to ensure proper wheel mounting.

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, dial indicator, torque wrench, brake cleaner.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery if working near electrical components.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Jack up the vehicle and securely place it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to check rotor runout; a reading above 0.002 inches indicates warping.
Replacement:
- If warped, remove the caliper by unbolting it from the bracket.
- Remove the brake rotor by unbolting it from the hub.
- Clean the hub surface where the rotor mounts.
- Install new rotors, ensuring they are seated properly and secured with bolts to manufacturer torque specs (usually around 70-80 ft-lbs).

4. Inspect and Replace Brake Pads

Check brake pad thickness; pads worn below 3mm should be replaced.
Remove any retaining clips and slide the old pads out of the caliper bracket.
Install new brake pads, applying anti-squeal grease on the back of the pads.
Reinstall the caliper over the new pads.

5. Reassemble

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 76 ft-lbs).
Reconnect the battery if it was disconnected.
