Diagnostic Steps

2

Solution

1. Preparation

Gather necessary tools: jack, jack stands, lug wrench, caliper gauge, and possibly a brake pad spreader.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Lift the Vehicle

Loosen the lug nuts on the front or rear wheels (depending on which brakes you are inspecting) slightly while the vehicle is still on the ground.
Use a jack to lift the vehicle and securely place jack stands underneath for safety.
Remove the lug nuts completely and take off the wheel.

3. Inspect the Brake Pads

Look at the brake pads through the caliper. If the pad thickness is less than 1/4 inch (6 mm), they need replacement.
Use a caliper gauge to measure the thickness of the brake pads. Ensure the measurement is taken from the area that contacts the rotor.
Inspect the rotor surface for scoring or grooves, which may indicate the need for rotor replacement as well.

4. Replace Brake Pads (if necessary)

If the pads need replacing, remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
Use a brake pad spreader to push back the caliper piston for easier installation of new pads.
Remove the old pads from the caliper bracket and replace them with new ones, ensuring they are properly aligned.
Reinstall the caliper and torque the bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).

5. Reassemble the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque (usually around 80-100 ft-lbs).
