Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the wheel using a socket set.
- Inspect the brake pads; if worn below specifications, replace them.
- Compress the caliper piston using a brake caliper tool.
- Install new brake pads according to manufacturer specifications.
Tools Required:
- Socket set
- Brake caliper tool
- Torque wrench

3. Resurface or Replace Brake Rotors

Sub-steps:
- Remove the caliper and hang it with a bungee cord (do not let it dangle from the brake line).
- Remove the rotor and inspect for warping; if warped, either resurface or replace.
- Clean the hub surface before installing new or resurfaced rotors.
- Reinstall the caliper and torque to manufacturer specifications.
Tools Required:
- Torque wrench
- Impact wrench (if necessary for rotor removal)

4. Inspect Suspension Components

Sub-steps:
- Visually inspect control arms, bushings, and tie rods for wear or damage.
- Replace any worn components as needed, following manufacturer specifications for torque.
Tools Required:
- Socket set
- Torque wrench

5. Wheel Bearings Check

Sub-steps:
- Lift the vehicle and check for play in the wheel bearings by shaking the wheel at the 12 and 6 o’clock positions.
- If there is excessive play, remove the hub and replace the wheel bearings.
Tools Required:
- Bearing puller
- Torque wrench
