Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery for safety if working on electronic components.

2. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, brake rotor puller, socket set.
Sub-steps:
1. Remove the wheel lug nuts using a socket and wrench.
2. Lift the vehicle with a jack and secure it on jack stands.
3. Remove the wheel to access the brake assembly.
4. Remove the caliper by unscrewing the caliper mounting bolts, then slide the caliper off the rotor.
5. Remove the brake rotor by unscrewing any retaining screws and pulling it off the hub.
6. Inspect the rotor for warping using a runout gauge; replace if warped beyond specifications.
7. Install new rotors, ensuring they are properly seated against the hub and secured with retaining screws.

3. Replace Brake Pads

Tools Required: Brake caliper tool, socket set.
Sub-steps:
1. With the caliper removed, inspect the brake pads for wear; replace if worn down.
2. Compress the caliper piston using a brake caliper tool to fit the new pads.
3. Install new brake pads into the caliper bracket.
4. Reinstall the caliper over the new pads and tighten the caliper mounting bolts to the manufacturer’s torque specifications.

4. Inspect Suspension Components

Tools Required: Socket set, pry bar.
Sub-steps:
1. Check control arms, bushings, and sway bar links for signs of wear or damage.
2. Replace any worn or damaged suspension components as necessary.

5. Align Wheels

Tools Required: Wheel alignment equipment.
Sub-steps:
1. Take the vehicle to a professional for a four-wheel alignment.
2. Ensure that the alignment is set to the manufacturer’s specifications.
