Symptoms

•Steering wheel shakes or vibrates during braking
•Vehicle pulls to one side when braking
•Brake pedal pulsates or feels uneven
•Increased stopping distance
•Unusual noises from the brakes during application

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a runout gauge.
2
Check brake pads for thickness and wear; replace if worn beyond specifications.
3
Examine brake calipers for proper operation and ensure they are not sticking.
4
Inspect suspension components (e.g., control arms, tie rods) for wear or damage.
5
Verify tire balance and alignment to rule out other causes of vibration.

Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Loosen lug nuts using a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Use a runout gauge to measure rotor runout; if it exceeds specifications, replace the rotor.
If replacing, remove the caliper by unbolting the caliper bracket and sliding it off the rotor.
Unscrew the rotor from the hub, noting any retaining screws.
Install the new rotor, ensuring it is secured properly.

4. Inspect and Replace Brake Pads

Remove the caliper from the brackets if not already done.
Slide out the old brake pads.
Compare new pads to old ones for thickness; replace if necessary.
Apply brake grease to the back of the new pads to prevent noise and install them.

5. Reassemble Components

Reinstall the caliper over the new pads and torque bolts to manufacturer specifications.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to specifications.
