Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the vehicle battery to ensure safety.

2. Inspect and Replace Brake Rotors

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, socket set.
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel using the lug wrench.
3. Inspect the brake rotor for warping by checking with a runout gauge; replace if necessary.
4. If replacing, remove the caliper by loosening bolts and hang it securely using a wire.
5. Remove the brake rotor by sliding it off the hub.
6. Clean the hub surface with brake cleaner before installing the new rotor.
7. Install the new rotor and reattach the caliper, tightening the bolts to the manufacturer's torque specifications.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader tool, socket set.
Sub-steps:
1. If the pads are worn, remove the old pads from the caliper bracket.
2. Use a brake pad spreader tool to compress the caliper piston.
3. Install new brake pads ensuring they are seated properly.
4. Reassemble the caliper and wheel.

4. Check Wheel Alignment and Balance

Tools Required: Alignment tool (if doing in-house), balance weights.
Sub-steps:
1. Take the vehicle to a professional service for alignment checks.
2. Ensure that wheel balancing is performed if uneven tire wear is observed.
