Diagnostic Steps

1
Inspect brake components for wear, including pads and rotors.
2
Check rotor runout using a dial indicator to determine if they are warped.
3
Examine suspension components, including control arms and bushings, for damage or wear.
4
Verify wheel alignment and balance.
5
Inspect tire condition and pressure for irregularities.

Solution

1. Preparation

Gather tools and materials: brake cleaner, new brake pads, new rotors (if needed), socket set, torque wrench, jack stands, and a wheel chock.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Lift the Vehicle

Sub-steps:
1. Loosen the lug nuts of the front wheels while the vehicle is on the ground.
2. Use a jack to lift the front of the vehicle and secure it with jack stands.
3. Remove the front wheels.

3. Inspect and Replace Brake Pads and Rotors

Sub-steps:
1. Remove the caliper by unbolting it from the bracket; support it with a bungee cord to avoid strain on the brake line.
2. Remove the old brake pads and inspect the caliper for any damage.
3. If rotors are warped (greater than .002 inches runout), remove them by unbolting the rotor from the hub.
4. Install new rotors if necessary, ensuring they are properly aligned.
5. Install new brake pads and compress the caliper piston using a c-clamp.
6. Reattach the caliper and torque bolts to the manufacturer's specifications (typically around 25-30 lb-ft).

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect control arms, ball joints, and bushings for cracks or excessive wear.
2. If any components are damaged, replace them according to the manufacturer’s specifications.

5. Reassembly

Sub-steps:
1. Reinstall the front wheels and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and torque the lug nuts to the specified value (typically 76-80 lb-ft).

6. Final Check

Sub-steps:
1. Pump the brake pedal a few times to ensure proper brake pad seating.
2. Test drive the vehicle to check for vibrations during braking.
