Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Secure the vehicle with wheel chocks and elevate it using a jack and jack stands.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts while the vehicle is still on the ground.
2. Raise the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully lift the caliper off the rotor and support it with a bungee cord to avoid hanging from the brake line.
3. Inspect the brake pads for wear; replace them if they are less than 3mm thick.
4. If replacing, remove the old pads and install new ones, ensuring they are properly seated.

4. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. Check rotor surface for any scoring or uneven wear.
2. If warped or damaged, either resurface the rotors or replace them with new ones.
3. If resurfacing, ensure the rotor is within the manufacturer’s specifications for minimum thickness.

5. Reassemble Components

Sub-steps:
1. Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and tighten the lug nuts in a crisscross pattern to the specified torque.

6. Final Check

Sub-steps:
1. Pump the brake pedal a few times to ensure proper brake pad seating.
2. Test the brakes at low speed to confirm the grinding noise is resolved.
