Diagnostic Steps

1
Inspect brake pads for wear and proper installation.
2
Check brake rotors for warping or uneven surfaces.
3
Examine suspension components for wear or damage, focusing on control arms and bushings.
4
Inspect wheel bearings for play or damage.
5
Verify tire condition and balance, looking for uneven wear or proper inflation.

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, dial indicator (for rotor measurement), inspection mirror.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Inspect the brake pads for wear; replace if less than 3mm thick.
3. Clean the caliper and bracket with brake cleaner.
4. Install new brake pads, ensuring they are properly seated.
5. Reattach the wheel and torque to manufacturer specifications (typically 100-150 ft-lbs).

3. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. Remove the brake caliper and suspend it safely.
2. Remove the brake rotor from the hub.
3. Measure rotor thickness and check for warping with a dial indicator; replace if out of specification (typically more than 0.002 inches).
4. If resurfacing is possible, ensure the rotor is within the allowable thickness after resurfacing.
5. Reinstall the rotor and caliper securely.

4. Check Suspension Components

Sub-steps:
1. Inspect control arms, bushings, and ball joints for wear or damage.
2. If any components are worn, replace them with OEM or high-quality aftermarket parts.
3. Ensure all connections are tight and secure.

5. Wheel and Tire Inspection

Sub-steps:
1. Inspect tires for uneven wear or damage.
2. Check tire pressure and inflate to the recommended PSI.
3. Balance the wheels if necessary.
