Solution

1. Preparation

Gather all tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel Assembly

Tools Required: Jack and jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts on the wheel where grinding is heard.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and suspend it (do not let it dangle from the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Compare new brake pads with the old ones to ensure proper fit.
5. Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake rotor puller (if necessary), torque wrench.
Sub-steps:
1. Check the rotor for any signs of damage, scoring, or warping.
2. If replacement is needed, remove the rotor from the hub.
3. Install the new rotor, ensuring it is seated properly.
4. Torque the rotor bolts to the manufacturer’s specifications.

5. Reassemble Brake System

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Reattach the caliper over the new brake pads and rotor.
2. Secure the caliper with the bolts and torque to specifications.
3. Reinstall the wheel and tighten the lug nuts in a crisscross pattern.

6. Final Checks

Tools Required: Brake fluid, funnel.
Sub-steps:
1. Reconnect the negative battery terminal.
2. Check and top off the brake fluid if necessary.
3. Pump the brake pedal several times to seat the pads against the rotor.
