⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety goggles and gloves when working on the vehicle.
•Ensure the vehicle is securely supported on jack stands before removing wheels or working under it.
•Allow time for brake components to cool to avoid burns.

Symptoms

•Vibrations felt through the steering wheel or brake pedal when braking
•Increased stopping distance
•Noises such as grinding or squeaking while braking
•Uneven wear on brake pads or rotors
•Steering wheel pulling to one side while braking

Diagnostic Steps

1
Inspect brake rotors for warping or excessive wear using a dial indicator gauge.
2
Check brake pads for wear and ensure they are within specifications.
3
Examine the brake calipers for proper operation and ensure they are not sticking.
4
Inspect suspension components, including control arms and bushings, for wear or damage.
5
Check tire condition and balance to rule out vibration issues originating from the tires.
6
Scan for any brake system-related error codes using an OBD-II scanner.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.

2. Remove Wheel

Use a jack to lift the vehicle and support it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Measure the rotor thickness using a micrometer; replace if below minimum specifications.
- Check for warping using a dial indicator; if warped, resurface or replace the rotor.
Inspect Brake Pads:
- Check the thickness of the brake pads; replace if below 3mm.
- Ensure the pads are seated correctly in the caliper.

4. Inspect Calipers and Suspension

Caliper Inspection:
- Ensure calipers are free from rust and can slide smoothly; lubricate sliding pins if necessary.
- Check for leaks in the caliper seal; replace if necessary.
Suspension Inspection:
- Check control arms, bushings, and struts for any signs of wear; replace damaged components.

5. Reassemble and Reinstall Wheel

Reinstall the brake components in reverse order, ensuring all bolts are torqued to manufacturer specifications.
Replace the wheel and lug nuts, and lower the vehicle.
