Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Tools Required: C-clamp, brake cleaner, torque wrench.
Sub-steps:
1. Remove the caliper by unbolting the caliper bracket.
2. Use a C-clamp to compress the caliper piston.
3. Remove the old brake pads and clean the caliper bracket with brake cleaner.
4. Install new brake pads, ensuring they are correctly aligned.
5. Reinstall the caliper and torque the bolts to manufacturer specifications.

4. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, brake rotor removal tool (if necessary).
Sub-steps:
1. Check the rotors for warping using a dial indicator; replace if necessary.
2. If replacing, remove the old rotor by unbolting it from the hub.
3. Install new rotors and torque bolts to manufacturer specifications.

5. Reinstall Wheel

Tools Required: Lug wrench, torque wrench.
Sub-steps:
1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts, then lower the vehicle.
3. Torque the lug nuts to manufacturer specifications.

6. Test Drive

Sub-steps:
1. Carefully drive the vehicle to ensure the braking system operates smoothly.
2. Monitor for any vibrations during braking.
