Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Brake Rotors

Tools Required: Jack and jack stands, lug wrench, torque wrench, rotor puller (if needed).
Sub-steps:
1. Lift the vehicle and remove the front wheels.
2. Inspect the brake rotors for warping using a dial indicator or visual inspection.
3. If warped, remove the caliper and bracket to access the rotor.
4. Remove the rotor by unscrewing any retaining screws or using a rotor puller.
5. Install new rotors ensuring they are properly seated and secured with the appropriate torque (usually around 80-100 ft-lbs).

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake pad spreader, brake cleaner.
Sub-steps:
1. Remove the caliper from the rotor after the rotor replacement.
2. Remove the old brake pads and inspect the caliper for any damage.
3. Clean the caliper and bracket with brake cleaner.
4. Install new brake pads, ensuring they fit snugly in the caliper brackets.
5. Reinstall the caliper over the new pads and torque to manufacturer specifications.

4. Examine and Replace Suspension Components

Tools Required: Socket set, pry bar, torque wrench.
Sub-steps:
1. Inspect control arms, bushings, and struts for any visible wear or damage.
2. Replace any worn components with OEM parts.
3. Torque all suspension bolts to manufacturer specifications.

5. Wheel Alignment and Balance

Tools Required: Alignment tools or access to an alignment machine.
Sub-steps:
1. Have the vehicle's wheels aligned by a professional to ensure proper tracking.
2. Balance the wheels if necessary to prevent vibrations.
