Diagnostic Steps

2
Check the brake rotors for scoring, warping, or uneven wear.
3

Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, lug wrench, brake cleaner, clean rags, caliper gauge, OBD-II scanner.
Park the vehicle on a level surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Turn off the engine and disconnect the battery for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads: Measure the thickness of the brake pads. If they are less than 3mm, replace them.
Brake Rotors: Check for scoring or warping. If grooves are present or the surface is uneven, resurfacing or replacing the rotors is necessary.
Brake Hardware: Clean caliper slides and brackets with a wire brush and brake cleaner. Replace any corroded components.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts with a socket set and carefully slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are oriented correctly and seated properly.
Compress the caliper piston using a brake caliper tool to allow for the thicker new pads.

5. Reassemble and Test

Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications (generally around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (usually about 76 ft-lbs).
Reconnect the battery and test the brake system before a test drive.
