Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Remove the brake caliper by unscrewing the caliper bolts and carefully lifting it away from the rotor.
3. Detach the rotor by removing the holding screws (if applicable) and sliding it off the hub.
4. Inspect the rotor for warping or scoring; if damaged, replace with new rotors.
5. Install new rotors, ensuring they are properly seated on the hub.
6. Reattach the brake caliper and torque the bolts to manufacturer specifications (usually around 20-30 ft-lbs).

3. Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Clean the caliper bracket and apply brake grease to the contact points.
3. Install new brake pads, ensuring they are oriented correctly.
4. Compress the caliper piston back into the caliper housing if necessary.
5. Reattach the caliper over the new pads and secure it.

4. Check and Adjust Wheel Alignment

Sub-steps:
1. Inspect suspension components for damage or wear (e.g., control arms, bushings).
2. If necessary, take the vehicle to a professional alignment shop for adjustments.

Tools Required:

Socket set
Torque wrench
Brake cleaner
Brake grease
Dial indicator (for rotor runout measurement)

Parts Required:

Brake rotors (if warped/damaged)
Brake pads (if worn)
Caliper guide pins (if damaged)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Disconnect battery before working on electrical systems.
