⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow the vehicle to cool down before touching brake components to avoid burns.

Symptoms

•Shaking or vibration in the steering wheel during braking
•Pulsating brake pedal
•Increased stopping distance
•Uneven brake wear (visible upon inspection)
•Noise from the brakes (grinding or squeaking)

Diagnostic Steps

1
Inspect the brake rotors for warping or uneven wear using a run-out gauge.
2
Check brake pads for thickness and even wear across the surface.

Solution

1. Preparation

Gather necessary tools and parts.
Secure the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the brake system.

2. Remove Wheel and Brake Components

Tools Required: Jack, jack stands, lug wrench, socket set.
Loosen lug nuts using a lug wrench while the vehicle is still on the ground.
Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Components

Check the brake rotors for warping:
- If warped, replace the rotors with new ones. Ensure they meet manufacturer specifications.
Inspect brake pads:
- Replace if they are worn below the minimum thickness.
- Clean the caliper and apply brake grease to the pad backing.
Reinstall the brake components in reverse order, ensuring proper torque specifications for the caliper bolts and lug nuts.

4. Wheel Alignment and Balancing

If necessary, take the vehicle to a professional for wheel alignment and balancing.
Ensure all tires are in good condition and properly inflated.
