Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Allow the vehicle to cool down before performing any maintenance.

Symptoms

•Grinding noise occurs during braking
•Vibration in the brake pedal
•Reduced braking efficiency
•Squeaking or squealing noises in addition to grinding
•Warning light for brakes may illuminate

Diagnostic Steps

1
Inspect the brake pads for wear and thickness using a caliper gauge.
2
Check the brake rotors for scoring, warping, or uneven wear.
3
Examine the brake calipers for proper function and any signs of sticking.
4
Inspect the brake hardware (shims, clips) for damage or misalignment.
5
Scan for any error codes related to the braking system using an OBD-II scanner.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen the lug nuts using a socket set.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect Brake Components

Remove the brake caliper by unbolting it from the bracket (usually requires a socket wrench).
Carefully hang the caliper using a bungee cord or similar tool to avoid stress on the brake line.
Remove the brake pads from the caliper bracket. Check for wear indicators and replace if less than 3mm thick.
Inspect the brake rotor; if worn or damaged, proceed to replace it.

4. Replace Brake Pads and Rotors (if necessary)

If replacing pads, apply brake grease to the back of the new pads to minimize noise.
If replacing rotors, remove the old rotor and install the new rotor, ensuring it is properly seated.
Reattach the caliper over the new pads and rotor, tightening the caliper bolts to the manufacturer's torque specification (usually around 25-35 ft-lbs).

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specification (typically 80-100 ft-lbs).
Repeat for the other side if necessary.
