Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Sub-steps:
1. Loosen lug nuts slightly on the front wheels while the vehicle is on the ground.
2. Use a hydraulic jack to lift the front of the vehicle.
3. Secure with jack stands and remove the front wheels.
Tools Required: Hydraulic jack, jack stands, lug wrench.

3. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
2. Hang the caliper using a bungee cord or wire to avoid stressing the brake line.
3. Remove the rotor by unscrewing any retaining screws or pulling it off the hub.
4. Inspect the rotor for warping using a dial indicator; replace if necessary.
5. Install new rotors, securing them with retaining screws.
Tools Required: Socket set, bungee cord, dial indicator, torque wrench.
Torque Values: Follow manufacturer specifications for caliper bolts (typically around 20-30 ft-lbs).

4. Inspect and Replace Brake Pads

Sub-steps:
1. Remove old brake pads from the caliper bracket.
2. Compare the thickness of old pads with new ones; replace if worn beyond specifications.
3. Apply anti-squeal lubricant to the back of new pads before installation.
4. Reinstall the caliper over the new pads and torque caliper bolts to specifications.
Tools Required: Torque wrench, anti-squeal lubricant.
Safety Warnings: Ensure caliper pistons are compressed before reinstallation.

5. Inspect Suspension Components

Sub-steps:
1. Visually inspect control arms, tie rods, and bushings for signs of wear or damage.
2. Wiggle components by hand to check for play; replace any worn parts.
Tools Required: None specifically for visual inspection.

6. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the front wheels and hand-tighten lug nuts.
2. Lower the vehicle with the hydraulic jack and remove jack stands.
3. Torque the lug nuts to specifications (typically around 100-120 ft-lbs).
Tools Required: Hydraulic jack, jack stands, torque wrench.
