Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath.
•Allow brakes to cool before inspecting to avoid burns.

Symptoms

•Grinding noise when applying brakes
•Vibration in the brake pedal
•Reduced braking efficiency
•Warning light for brake system illuminated
•Possible burning smell from brakes

Diagnostic Steps

1
Inspect brake pads for wear and tear using a visual inspection or measuring tool.
2
Check brake rotors for scoring, warping, or damage by examining surface condition.
3
Inspect brake calipers for proper operation and any signs of sticking or leakage.
4
Examine brake fluid level and condition in the master cylinder reservoir.
5
Perform a road test to verify the noise occurs only when braking.

Solution

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, basic socket set, brake cleaner, and a multimeter.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery for safety.

2. Remove Wheel

Loosen the lug nuts on the wheel where the grinding noise is occurring.
Lift the vehicle using the jack and secure it with jack stands.
Completely remove the lug nuts and wheel to access the brake assembly.

3. Inspect Brake Components

Remove the caliper by unscrewing the caliper bolts (typically 12-14 Nm torque).
Carefully slide the caliper off the rotor, supporting it to avoid strain on the brake line.
Inspect the brake pads for wear; if they appear worn down to 3mm or less, they should be replaced.
Check the rotor for scoring, grooves, or warping. If damaged, rotors should be resurfaced or replaced.

4. Replace Brake Pads (if necessary)

If brake pads are worn, remove them from the caliper bracket.
Apply brake grease to the back of the new pads to prevent noise.
Install new pads into the caliper bracket ensuring they are properly seated.

5. Reassemble Brake Components

Reinstall the caliper over the new pads and secure it with the caliper bolts.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then use the torque wrench to tighten the lug nuts to the manufacturer’s specifications (typically 100 Nm).

6. Final Checks

Reconnect the battery.
Pump the brakes a few times to ensure proper brake pad seating and brake fluid pressure.
