⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely lifted and supported before working on the brakes.
•Disconnect the battery before beginning work on the electrical components of the brake system.

Symptoms

•Squeaking or squealing noise when braking
•Grinding noise when brakes are applied
•Reduced braking efficiency or longer stopping distance
•Vibration or pulsation felt through the brake pedal
•Dashboard warning light indicating brake system issue
•Visual inspection shows worn brake pads or less than 1/8 inch of pad material

Diagnostic Steps

1
Inspect the brake pads through the wheel spokes for visible wear.

Listen for unusual noises (squealing or grinding) while braking.
3
Check for vibrations or pulsations in the brake pedal during braking.
4
Measure the thickness of the brake pads using a caliper; compare to manufacturer specifications.
5
Inspect the brake rotors for scoring or uneven wear.
6
Scan for any brake system warning codes using an OBD-II scanner.

Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, brake pad gauge, torque wrench, and safety glasses.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery if necessary for safety.

2. Lift the Vehicle

Use the lug wrench to loosen lug nuts on the wheel where brake pads will be inspected.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the brake system.

3. Inspect Brake Pads and Rotors

Visually inspect brake pads for thickness. Replace if they are less than 1/8 inch.
Check the surface of the brake rotors for scoring or rust. Replace rotors if damaged.
Ensure brake calipers are functioning correctly and not leaking brake fluid.

4. Replace Brake Pads (if needed)

Remove the caliper bolts using the appropriate socket size.
Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang).
Remove the old brake pads from the caliper bracket.
Compress the caliper piston using a brake caliper tool to make space for the new pads.
Install new brake pads into the caliper bracket.
Reattach the caliper over the new pads and tighten caliper bolts to manufacturer specifications (typically 20-25 ft-lbs).

5. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification (typically 76 ft-lbs).
Reconnect the battery if it was disconnected.
