Solution

1. Preparation

Ensure the vehicle is on a flat surface and set the parking brake.
Gather required tools and parts.

2. Inspect and Replace Brake Pads and Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Check the brake pads for thickness; replace if worn below specification (usually 3mm).
3. Remove caliper bolts and lift the caliper away from the rotor; support it to avoid strain on the brake line.
4. Remove the old rotor by unscrewing the retaining screws (if equipped) and pulling it off the hub.
5. Install the new rotor and secure it with retaining screws.
6. Install new brake pads in the caliper bracket.
7. Reattach the caliper and torque bolts to manufacturer's specifications (typically around 25-35 Nm).

3. Check and Adjust Wheel Alignment

Sub-steps:
1. Inspect wheel alignment using an alignment tool.
2. Adjust camber, caster, and toe settings as per manufacturer specifications.
3. Test drive to ensure alignment is correct.

4. Inspect and Replace Wheel Bearings (if necessary)

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Remove the wheel and brake assembly.
3. Check for play in the wheel bearings by spinning the hub.
4. If play is detected, remove and replace the wheel bearings.
5. Reassemble the wheel and brake assembly.
