•Allow brake components to cool if they have been recently used to avoid burns.

Symptoms

•Steering wheel vibration during braking
•Shaking felt in the brake pedal
•Vehicle pulling to one side when braking
•Uneven wear on brake pads or rotors
•Grinding or squeaking noises during braking

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.

Solution

1. Preparation

Gather tools: jack stands, lug wrench, dial indicator, torque wrench, and brake cleaner.
Ensure the vehicle is parked on a flat surface and the engine is turned off.

2. Wheel Removal

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Inspection

Inspect the brake rotor:
- Use a dial indicator to measure any warping; if the runout exceeds manufacturer specifications, replace the rotor.
Check the brake pads:
- Measure the thickness; replace if below 1/4 inch or if uneven wear is observed.

4. Suspension Check

Visually inspect control arms and tie rods for any signs of wear or damage.
Move components by hand to check for excessive play; replace any worn parts.

5. Brake Caliper Check

Inspect the calipers for sticking or improper operation:
- Remove caliper bolts and check the sliding pins; lubricate or replace if necessary.
Reassemble all components, ensuring all bolts are torqued to the manufacturer’s specifications.

6. Wheel Reinstallation

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value using a torque wrench.
