Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Sub-steps:
1. Loosen wheel lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the wheel completely.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, brake cleaner
Sub-steps:
1. Remove the caliper by unbolting it from the bracket; hang it safely to avoid stress on the brake line.
2. Remove the brake pads from the caliper and bracket.
3. Remove the rotor by unscrewing the retaining screws if applicable.
4. Inspect the rotor surface for warping. If warped, replace with new rotors.
5. Clean the new rotor with brake cleaner before installation.

4. Replace Brake Pads

Tools Required: Brake pad spreader tool
Sub-steps:
1. Install new brake pads into the caliper bracket.
2. Use the brake pad spreader tool to compress the caliper piston back into the caliper to accommodate the new pads.
3. Reinstall the caliper over the new pads and torque bolts to manufacturer specifications.

5. Reassemble and Test

Tools Required: Torque wrench
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the specified value.
3. Reconnect the battery and pump the brake pedal a few times to seat the pads.
4. Perform a test drive to check for any vibrations during braking.
