Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on brake systems.
•Allow the vehicle to cool before working on the brakes to prevent burns.

Symptoms

•Grinding noise when applying brakes
•Vibration or pulsation in the brake pedal
•Reduced braking effectiveness
•Warning light on the dashboard (if applicable)
•Brake pads or rotors may show signs of wear

Diagnostic Steps

1
Inspect brake pads for wear thickness and condition.
2
Check brake rotors for scoring, warping, or damage.
3
Examine brake calipers for proper function and alignment.

Solution

1. Preparation

Gather tools and parts:
- Tools: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.
- Parts: New brake pads, rotors (if necessary), brake lubricant.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Raise the Vehicle

Loosen the lug nuts on the wheel where grinding is heard.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and support it to avoid damaging the brake line.
Remove the old brake pads from the caliper bracket.
Compare the thickness of the old pads to the new ones; if they are worn down to 3mm or less, they need replacement.
Apply brake lubricant to the backing of the new pads and install them into the caliper bracket.

4. Inspect and Replace Rotors (if necessary)

Check the condition of the rotor surface. If there are deep grooves or significant scoring, replace the rotor.
Remove the caliper bracket if rotor replacement is needed.
Unscrew and remove the rotor from the hub.
Install the new rotor, ensuring it is seated properly.

5. Reassemble Braking Components

Reattach the caliper over the new pads and rotor.
Secure the caliper with the appropriate torque specifications (usually around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle and Test

Remove jack stands and lower the vehicle using the jack.
Torque the lug nuts to the manufacturer's specifications (typically around 76-80 ft-lbs).
Test drive the vehicle to ensure the grinding noise has ceased and brakes function properly.
