⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety gear when working on vehicles.
•Allow brakes to cool before inspecting to prevent burns.

Symptoms

•Shaking or vibration felt through the steering wheel during braking
•Pulsating brake pedal when applying brakes
•Increased stopping distance
•Noise coming from the brakes (grinding or squeaking)
•Uneven wear on brake pads or rotors
•Steering wheel misalignment

Diagnostic Steps

1
Inspect brake rotors for warping or scoring using a dial indicator.
2
Check brake pads for uneven wear and thickness.
3
Examine brake calipers for proper function and sticking.
4
Assess suspension components, including control arms and bushings, for wear or damage.
5
Inspect wheel alignment and tire condition for abnormalities.
6
Scan for any trouble codes that may relate to braking or stability control systems.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety gloves and glasses.

2. Wheel Removal

Use a lug wrench to loosen the lug nuts on the affected wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Inspection

Rotors:
- Measure rotor thickness with a micrometer; replace if below specifications (usually 1.0mm over minimum thickness).
- Check for warping using a dial indicator; replace if warped.
Brake Pads:
- Inspect pad thickness; replace if below 3mm.
- Look for uneven wear patterns; replace as necessary.
Calipers:
- Check calipers for proper operation; ensure they are not seized or sticking.
- Clean and lubricate caliper pins if required.

4. Replacement (if necessary)

Replace warped or damaged rotors with OEM or high-quality aftermarket rotors.
Replace worn brake pads with OEM or high-quality aftermarket pads.
Reinstall calipers and ensure they are torqued to manufacturer specifications (usually around 25-30 ft-lbs).

5. Wheel Reinstallation

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (usually around 80-100 ft-lbs).

6. Test Drive

Perform a test drive to ensure the issue has been resolved.
Monitor the braking performance and listen for any unusual noises.
