⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety goggles and gloves when working on the vehicle.
•Disconnect the battery before working on electrical systems.

Symptoms

•Grinding noise during acceleration or deceleration
•Noise increases with vehicle speed
•Vibration felt through the steering wheel or floor
•Possible burning smell if related to brakes
•Decreased braking performance
•Fluid leaks under the vehicle

Diagnostic Steps

1
Inspect the brake components for wear and damage, including brake pads, rotors, and calipers.
2
Check the wheel bearings for any play or roughness by lifting the vehicle and spinning the wheels.
