⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the brakes to cool before touching any components after driving.

Symptoms

•Vibration felt in the steering wheel during braking
•Pulsation in the brake pedal
•Increased stopping distance
•Potential noise such as grinding or squeaking when braking
•Uneven wear on brake pads or rotors

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator or straight edge.
2
Check brake pads for thickness and even wear; ensure they are not glazed or worn down.
3
Examine suspension components (control arms, bushings, and ball joints) for damage or wear.
4
Test brake calipers for proper operation; ensure they are not sticking or seized.
5
Verify wheel balance and alignment to rule out related vibration issues.

Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a level surface and engage the parking brake.
Gather safety gear (gloves, goggles).

2. Remove Wheel

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

3. Inspect and Replace Brake Components

Inspect Brake Rotors:
- Use a dial indicator to check for warping. Replace rotors if they exceed manufacturer specifications (typically more than 0.002 inches).
Replace Brake Pads:
- Remove caliper bolts with a socket wrench and slide the caliper off.
- Replace pads with new ones, ensuring they are installed in the correct orientation.
Check Caliper Functionality:
- Ensure calipers move freely. If they are stuck, clean or replace as necessary.

4. Inspect Suspension Components

Visually inspect control arms, bushings, and ball joints for wear or damage. Replace any worn components.

5. Reassemble and Rebalance

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
Perform a wheel balance if necessary.
