2
Check for any debris or foreign objects lodged in the brake assembly.
3
Examine brake rotors for grooves, scoring, or warping.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely raise it using jack stands.
Wear safety gloves and goggles.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel.
Raise the vehicle using a floor jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Pads: Check the thickness of the brake pads. If they are less than 3mm, they need replacement.
Remove Old Pads: Unbolt the caliper using a socket set and slide the caliper off the rotor. Support it with a bungee cord or hang it to prevent stress on the brake line.
Install New Pads: Slide the new brake pads into the caliper bracket. Ensure they fit snugly.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors: Measure the thickness and inspect for grooves or scoring; replace if they are below specifications or damaged.
Remove Rotors: If replacing, unbolt the rotor from the hub. Use a rotor puller if necessary.
Install New Rotors: Place the new rotor onto the hub and secure it with bolts to the manufacturer's torque specifications.

5. Reassemble and Test

Reattach the brake caliper over the new pads, ensuring it moves freely.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Pump the brake pedal a few times to seat the pads before driving.
