•Allow the brakes to cool before inspection to avoid burns.

Symptoms

•Vibrations felt through the steering wheel when braking
•Pulsating brake pedal during braking
•Shaking of the vehicle body when coming to a stop
•Increased stopping distance
•Unusual noise (squeaking or grinding) from the brake area

Diagnostic Steps

1
Inspect brake pads and rotors for wear and damage.
2
Check for warped brake rotors using a run-out gauge.
3
Examine brake calipers for proper operation and sticking.
4
Inspect suspension components for wear or damage (e.g., control arms, bushings).
5
Ensure wheel lug nuts are properly torqued.
6
Check for any loose or damaged wheel bearings.

Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the negative battery terminal to prevent electrical issues during the repair.

2. Inspect and Replace Brake Components

2.1. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Use a jack to lift the front or rear of the vehicle (depending on which wheels you are inspecting).
Secure the vehicle with jack stands and remove the wheel.

2.2. Inspect Brake Pads and Rotors

Check the thickness of the brake pads. Replace if they are below the minimum thickness (usually around 3mm).
Inspect the rotors for warping or scoring. If warped (greater than 0.003 inches run-out), replace the rotors.

3. Caliper Inspection and Maintenance

3.1. Check Calipers

Ensure calipers are not seized. If they do not move freely, they may need replacement.
If needed, remove caliper bolts and the caliper, then inspect the piston for damage.

4. Reassemble and Wheel Installation

4.1. Reinstall Components

If components were replaced, reinstall new brake pads and rotors in the reverse order of removal.
Reattach the caliper securely and torque the caliper bolts to the manufacturer’s specification (typically around 30 Nm).

5. Finish

5.1. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then torque the lug nuts to the manufacturer’s specification (generally around 120 Nm).
