Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and the vehicle is cool.

2. Inspect Brake Components

Sub-steps:
- Remove the wheel to access the brake assembly using a socket set.
- Check brake pads for thickness; replace if worn below the manufacturer's specification (usually 3mm).
- Inspect brake rotors for warping using a dial indicator; replace if warped beyond acceptable limits (typically 0.002 inches).

Tools Required:

Socket set
Torque wrench
Dial indicator

3. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
- If rotors are warped or pads are worn, remove the caliper bolts and slide the caliper off.
- Remove the old pads and install new ones, ensuring they are seated correctly.
- Replace the rotor by removing the retaining screws and installing the new rotor.
- Reinstall the caliper and torque bolts to manufacturer specifications (usually around 70 ft-lbs).

4. Check Brake Calipers

Sub-steps:
- Inspect caliper slides for lubrication; apply brake grease if necessary.
- Ensure calipers move freely and are not sticking.
- Reassemble all components and ensure proper torque specifications are met.

5. Inspect Suspension Components

Sub-steps:
- Check tie rods and control arms for wear or damage.
- Replace any worn bushings or joints as needed.
