•Ensure the vehicle is securely lifted before working under it.
•Allow brake components to cool down before handling.

Symptoms

•Grinding noise when brakes are applied
•Reduced braking performance
•Vibration in the brake pedal
•Warning light illuminated on the dashboard
•Increased stopping distance

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual check.
2
Check rotor surface for scoring or damage.
3
Examine brake calipers for proper operation and any seized components.
4
Inspect brake hardware (pins, springs, shims) for wear or damage.
5
Test brake fluid level and condition; look for contamination.
6
Conduct a road test to replicate the noise and assess braking performance.

Solution

Solution

1. Preparation

Gather tools and parts required for the repair.
Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, caliper tool, and safety goggles.
Safety Warnings: Ensure the vehicle is parked on a level surface and the parking brake is engaged. Disconnect the battery if working on electronic brake systems.

2. Remove Wheel

Use the lug wrench to loosen the wheel nuts.
Lift the vehicle with a jack and secure with jack stands.
Remove the wheel completely.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket.
Carefully slide the caliper off the rotor; hang it using a wire to avoid damaging the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pad backing for wear; replace if worn down to the indicator.
Install new brake pads ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or scoring. If damaged, replace the rotors.
Remove the caliper bracket if rotor replacement is needed.
Replace the rotor by loosening the retaining screws and sliding it off the hub.
Install new rotors and secure with retaining screws.

5. Reassemble Braking Components

Reattach the caliper over the new brake pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle off the jack stands.
Tighten the lug nuts to the specified torque in a star pattern.
Start the vehicle and pump the brakes to seat the pads before taking a test drive.
