Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect brake pads for uneven wear; replace if below recommended thickness (typically 3mm).
3. If replacement is needed, use quality OEM or equivalent pads.
4. Apply anti-squeak lubricant to the back of the new pads.

3. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the caliper using the appropriate socket size and hang it using a bungee cord (do not let it dangle by the brake line).
2. Remove the rotor; check for warping with a runout gauge.
3. Replace with new rotors if warped beyond specification (usually more than 0.002 inches).
4. Clean the hub surface and apply anti-seize compound to prevent rust.

4. Caliper Inspection and Repair

Sub-steps:
1. Check caliper pistons for smooth movement; clean or replace if sticking.
2. Inspect brake fluid level and quality; replace fluid if contaminated.
3. Reinstall the caliper and ensure it is properly torqued according to manufacturer specifications.

5. Suspension Component Inspection

Sub-steps:
1. Inspect control arms and bushings for play or wear.
2. Replace any worn components with OEM parts.
3. Reassemble and torque all components to the manufacturer's specifications.
