⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the vehicle to cool before working on the brakes.
•Disconnect the battery before working on electronic brake sensors, if applicable.

Symptoms

•Grinding noise when applying brakes
•Possible vibrations in the brake pedal
•Decreased braking performance
•Warning light on the dashboard (if applicable)
•Increased stopping distance

Diagnostic Steps

1
Inspect brake pads for wear; check if they are thin or worn down.
2
Examine brake rotors for grooves, warping, or damage.
3
Check brake calipers for proper operation and any sticking issues.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Place wheel chocks behind the rear wheels for additional safety.

2. Remove Wheel

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection: Check the brake pads for thickness; replace if less than 3mm.
Removal: Remove the caliper bolts using a socket wrench. Carefully slide the caliper off the rotor (do not disconnect the brake line).
Replacement: Remove old brake pads from the caliper bracket. Insert new brake pads, ensuring proper orientation and fit.

4. Inspect and Replace Brake Rotors (if necessary)

Inspection: Check rotors for grooves or warping; if damaged, they need replacement.
Removal: Remove the caliper bracket (if applicable) and slide off the rotor.
Replacement: Install new rotors, ensuring they fit snugly onto the hub.

5. Reassemble Components

Reattach the caliper bracket and caliper, ensuring all bolts are torqued to the manufacturer specifications (typically around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts to the manufacturer’s torque specification (usually 80-100 ft-lbs).

6. Test Brake Function

Before driving, pump the brakes several times to ensure pads are seated properly and the brake pedal feels firm.
