⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath.
•Allow the vehicle to cool before handling any brake components to avoid burns.

Symptoms

•Steering wheel shakes during braking
•Vehicle vibrates through the chassis
•Brake pedal pulsates or feels uneven
•Increased stopping distance
•Uneven wear on brake pads or rotors
•Possible noise from the brakes (squeaking or grinding)

Diagnostic Steps

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

Check brake pad thickness and condition visually and measure with calipers.
3
Examine the brake calipers for proper operation and any signs of sticking.
4
Inspect suspension components (control arms, ball joints, tie rods) for wear or damage.
5
Verify wheel alignment and balance to rule out other sources of vibration.
6
Scan for any error codes that may indicate a related issue in the braking system.

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, dial indicator, calipers, torque wrench, brake cleaner, and safety goggles.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if necessary for safety.

2. Remove the Wheel

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

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Use a dial indicator to measure rotor runout. If it exceeds manufacturer specifications, the rotor is warped.
If warped, replace rotors with new ones ensuring they are properly torqued upon installation.

B. Inspect Brake Pads

Measure the thickness of the brake pads using calipers. If they are below the minimum thickness, replace them.
Clean the caliper bracket and install new brake pads, ensuring proper alignment.

C. Inspect Calipers

Check for any signs of sticking or damage. If the caliper is not functioning correctly, replace it.

4. Reassemble Components

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specifications.

5. Final Checks

Reconnect the battery if it was disconnected.
Test the brake system by pressing the brake pedal before driving.
