Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the wheel using a socket set.
- Use a caliper to measure the thickness of the brake pads; replace if below specifications.
- Remove the caliper bracket bolts and slide out the caliper; carefully hang it to avoid stress on brake lines.
- Remove the old brake pads and install new ones, ensuring they are properly seated.
- Reattach the caliper and torque the bolts to manufacturer specifications (usually around 25-35 lb-ft).

3. Inspect and Replace Brake Rotors

Sub-steps:
- If rotors are warped (check with a micrometer), remove the caliper and bracket as previously stated.
- Remove the rotor by unscrewing the retaining screws or bolts.
- Install new rotors, ensuring they are clean and free from any grease.
- Reattach the caliper and bracket, and torque to manufacturer specifications.

4. Wheel Alignment and Tire Check

Sub-steps:
- Inspect tires for uneven wear; replace if necessary.
- Perform a wheel alignment according to manufacturer specifications using an alignment machine.
- Ensure all tires are inflated to the recommended pressure.
