Garage Gurus | Brake Rotor Thickness Variation and Lateral Runout

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.

Awesome video !
Dealing with a runout issue right now I’ll have to check out this weekend . New rotors , new hawk hps pads , calipers , lines , bled the system . Brakes work great until they are hot,then I get a shaky steering wheel that gets worse with heat . Once cooled down , back to normal .
I didn’t do the install so I’ll have to check the shops work .

Can worn suspension /bearings increase runout ?

He has some good points . I think what causes warping is a hot rotor hitting a water puddle .
