Often misdiagnosed as a warped rotor, a pulsating brake pedal can have a different cause. Master Trainer Ryan Payne of Garage Gurus explains how a thickness variation in the brake rotor is the cause of the brake pedal pulsation and that lateral runout contributes to the disc thickness variation condition. On the vehicle, Ryan shows the tools and setup need to measure lateral runout and then demonstrates the test. He then goes on to give suggestions on how to resolve the issue. Count on Garage Gurus to help you get your vehicle repair done right.
