⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety glasses and gloves while performing brake work.
•Ensure the vehicle is securely supported before working underneath it.

Symptoms

•Grinding noise when brakes are applied
•Decreased braking performance
•Vibration in the brake pedal
•Warning light on the dashboard (if applicable)
•Pulling to one side during braking

Diagnostic Steps

1
Inspect brake pads for wear; measure thickness and look for uneven wear patterns.
2
Check brake rotors for damage or warping; measure rotor thickness and look for grooves.
3
Examine brake calipers for proper function; ensure they are not sticking or leaking.
4
Inspect brake fluid level and condition; look for contamination or low fluid levels.
5
Test drive the vehicle to replicate the grinding noise while monitoring other brake performance issues.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Use wheel chocks to secure the vehicle.

2. Remove Wheel

Use a lug wrench to loosen lug nuts slightly.
Jack the vehicle up using a hydraulic jack, and securely support it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the thickness; if less than 3mm, they should be replaced.
Remove Brake Caliper: Use a socket set to remove the caliper mounting bolts. Support the caliper with a bungee cord or similar device to avoid straining the brake line.
Replace Brake Pads: Remove the old pads and install new pads, ensuring they are oriented correctly. Apply brake grease to the backing plate of the new pads to prevent noise.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotor: If the rotor is damaged, remove any retaining screws (if applicable) and slide the rotor off the hub.
Install New Rotor: Place the new rotor onto the hub, ensuring it sits flush. Reinstall any retaining screws.
Reinstall Brake Caliper: Position the caliper over the new pads and rotor. Tighten the caliper mounting bolts to the manufacturer’s specified torque.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern to ensure even pressure.
Repeat the process on the other side if needed.
Test the brakes at low speed to ensure proper function and check for any grinding noise.
