•Allow brakes to cool before inspection if the vehicle has been driven recently.

Symptoms

•Vibration felt in the steering wheel during braking
•Pulsating brake pedal
•Uneven wear on brake pads or rotors
•Increased stopping distance
•Noise from brakes (squeaking or grinding)

Diagnostic Steps

1
Inspect the brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pad thickness and condition for uneven wear or damage.
3
Examine suspension components (control arms, bushings, and tie rods) for wear or damage.
4
Verify wheel lug nut torque to ensure proper tightening.
5
Test brake calipers for proper operation and any sticking or binding.

Solution

Diagnostic Steps

1
Inspect the brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pad thickness and condition for uneven wear or damage.
3
Examine suspension components (control arms, bushings, and tie rods) for wear or damage.
4
Verify wheel lug nut torque to ensure proper tightening.
5
Test brake calipers for proper operation and any sticking or binding.

Solution

1. Preparation

Gather tools: jack stands, wheel chocks, lug wrench, dial indicator, and torque wrench.
Park the vehicle on a flat surface and engage the parking brake.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel completely.

3. Inspect Brake Components

Rotor Inspection
- Use the dial indicator to measure rotor runout; replace if out of spec (typically more than 0.002 inches).
- If warped, either resurface or replace the rotors.
Pad Inspection
- Check brake pads; replace if worn below 3mm thickness or unevenly worn.
Caliper Inspection
- Ensure calipers move freely and are not sticking. Clean or replace if necessary.

4. Inspect Suspension Components

Check for play in the control arms, ball joints, and tie rods. Replace any worn components as necessary.

5. Reassemble and Torque

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
