Diagnostic Steps

1
Inspect brake rotors for warping or damage using a dial indicator.
2
Check brake pads for uneven wear or contamination.
3
Examine brake calipers for proper function and any sticking issues.
4
Inspect wheel bearings for wear or play.
5

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure with jack stands to ensure stability.

3. Remove Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Inspect the wheel for any unusual wear or damage.

4. Inspect and Replace Brake Components

a. Brake Rotor Inspection

Use the dial indicator to measure rotor run-out.
If warping is present (more than 0.002 inches), replace the rotors.

b. Brake Pad Inspection

Remove the caliper bolts with a socket set and lift the caliper away from the rotor.
Inspect the pads for wear; replace if the thickness is below specification or if uneven wear is observed.

c. Caliper Check

Ensure the caliper slides freely on its pins; lubricate if necessary.
Replace if the caliper is sticking or damaged.

5. Reassemble Components

Reinstall the caliper and secure it with the caliper bolts to factory torque specifications (usually around 25-35 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer’s specification (typically around 75-90 ft-lbs).
