Diagnostic Steps

1
Inspect brake rotors for warping or uneven surfaces using a dial indicator.
2
Check the brake pads for wear and ensure they are not glazed or unevenly worn.
3
Examine suspension components, including control arms and tie rods, for any signs of wear or damage.
4

Solution

1. Preparation

Gather tools including a jack, jack stands, torque wrench, dial indicator, and brake cleaner.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspection: Use a dial indicator to check the rotor runout; if it exceeds manufacturer specifications, it is warped.
Removal: Remove the brake caliper and hang it securely without stressing the brake line. Remove the caliper bracket if necessary.
Replacement: Remove the old rotor and install the new rotor, ensuring it sits flush against the hub.
Tools Required: Socket set, torque wrench.

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if they are worn below the minimum thickness, replace them.
Remove the old pads and install new pads, ensuring they are correctly positioned in the caliper bracket.
Tools Required: Piston tool (if necessary for caliper retraction).

5. Reassemble and Torque

Reattach the caliper and caliper bracket (if removed). Torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the correct specifications.
