Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts using a socket wrench before lifting the vehicle.
2. Use a jack to lift the vehicle and secure with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Socket set, Jack, Jack stands

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper by loosening the caliper bolts with a socket wrench.
2. Carefully lift the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
3. Inspect the brake pads for wear; if the friction material is worn down to 1/8 inch or less, replace them.
4. Remove the old brake pads from the caliper bracket.
5. Install new brake pads, ensuring they are properly aligned and seated.
Tools Required: Socket set, Bungee cord

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the surface of the rotors for any scoring or warping.
2. If damaged, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
3. Install the new rotor, ensuring it is properly seated against the hub.
Tools Required: Torque wrench, Screwdriver (if rotor screws are present)

5. Reassemble Brake Components

Sub-steps:
1. Reposition the caliper over the new brake pads and rotor.
2. Tighten the caliper bolts to the manufacturer’s specified torque (usually around 20-25 ft-lbs).
3. Reinstall the wheel and tighten lug nuts in a crisscross pattern to ensure even pressure.
Tools Required: Torque wrench

6. Lower Vehicle and Test

Sub-steps:
1. Remove jack stands and lower the vehicle.
2. Tighten the lug nuts fully once the vehicle is on the ground.
3. Start the vehicle and pump the brakes a few times to set the pads against the rotors.
4. Test drive the vehicle to ensure the grinding noise is resolved.
