•Always use jack stands when working under a vehicle.
•Allow brakes to cool before inspecting or working on them to avoid burns.

Symptoms

•Squeaking or squealing noise during braking
•Grinding noise when brakes are applied
•Increased stopping distance
•Vibration or pulsation in the brake pedal
•Warning light illuminated on the dashboard (if equipped)
•Visual inspection shows less than 1/8 inch of pad material

Diagnostic Steps

1
Inspect the brake pad thickness visually through the wheel spokes.
2
Listen for abnormal noises when applying the brakes.
3
Check for any warning lights on the dashboard related to the braking system.
4
Measure brake pad thickness with a caliper or ruler.
5
Inspect the brake rotors for scoring or damage.
6
Check for any signs of brake fluid leaks around calipers.

Solution

Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, caliper gauge, flashlight.
Ensure vehicle is on a flat surface and the parking brake is engaged.

2. Raise the Vehicle

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels using the lug wrench.

3. Inspect Brake Pads

Locate the brake calipers and remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the brake rotor.
Check the thickness of the brake pads using a caliper gauge. Replace if thickness is less than 1/8 inch.
Inspect the condition of the brake pad material for cracking or excessive wear.

4. Inspect Brake Rotors

Check the brake rotors for signs of scoring, rust, or excessive wear.
Measure rotor thickness with a micrometer to ensure it meets manufacturer specifications.

5. Reassemble

If pads and rotors are in good condition, reposition the caliper and tighten the caliper bolts to manufacturer specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to specified torque (typically 80-100 ft-lbs).
