Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is on a level surface and engage the parking brake.
Lift the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Brake Components

A. Brake Pad Inspection

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect brake pads for thickness; replace if less than 3mm.
3. Clean the caliper and pad contact points with brake cleaner.
Tools Required: Socket set, brake cleaner.

B. Rotor Inspection

Sub-steps:
1. Check rotors for warping using a dial indicator.
2. If warped beyond specifications (usually 0.002 inches), replace the rotors.
3. Resurface rotors if within acceptable limits and not excessively worn.
Tools Required: Dial indicator, rotor resurfacing tools (if applicable).

3. Wheel and Suspension Check

Sub-steps:
1. Inspect all suspension components (control arms, ball joints) for wear.
2. Tighten or replace any loose or damaged components.
3. Check lug nut torque (typically 80-100 ft-lbs) and adjust as necessary.
Tools Required: Torque wrench, inspection tools.

4. Tire and Alignment Check

Sub-steps:
1. Inspect tires for uneven wear or damage; replace if necessary.
2. Check tire pressure and inflate to manufacturer’s specifications.
3. If misalignment is suspected, take the vehicle for a professional alignment.
Tools Required: Tire pressure gauge, alignment equipment (if applicable).
