Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety if working on the brake system.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the wheel using a socket set.
- If necessary, remove the brake caliper by loosening the caliper bolts.
- Remove the old brake pads from the caliper bracket.
- Inspect the caliper slides and lubricate if needed.
- Install new brake pads, ensuring they are correctly seated.
- Reattach the caliper and torque bolts to the manufacturer's specifications (usually around 25-35 lb-ft).

3. Inspect and Replace Brake Rotors

Sub-steps:
- If rotors are warped, remove the caliper and brake pads as detailed in the previous step.
- Remove the rotor by unscrewing the retaining screws if applicable, or slide it off the hub.
- Measure rotor thickness; if below specifications (typically 0.040 inches), replace with new rotors.
- Install new rotors, ensuring they are clean and free of grease.
- Reinstall brake pads and caliper as described earlier.

4. Check Suspension Components

Sub-steps:
- Visually inspect shocks, struts, and control arms for any signs of wear or damage.
- If any components are damaged, replace with OEM or high-quality aftermarket parts.
- Reassemble any disassembled parts and ensure proper torque specifications are followed.

5. Wheel Alignment and Balance

Sub-steps:
- Take the vehicle to a professional alignment shop.
- Ensure that both alignment and wheel balance are checked and corrected as necessary.

Tools Required:

Socket set
Torque wrench
Micrometer for rotor measurement
