The most common cause of brake vibration is improper bed-in of pads and rotors, or improper pad
selection for the specific driving environment. Rotor run-out may also cause vibration, but preci-
sion manufacturing and inspection typically mean that run-out is not an issue. Modern produc-
tion methods ensure that the rotor run-out is within +/- 0.002” when installed on a StopTech alumi-
num hat, and it controls thickness variation to within 0.0003”. Under the most extreme conditions,
any rotor may warp, but uneven pad deposition is a more typical cause of vibration. If the system
is not properly bedded-in, or if street pads are run on an open track, uneven pad deposits will occur,
causing an ever-worsening vibration. Failure to immediately address a pad deposition/vibration
issue may lead to permanent damage of the rotors. Please read and understand the bed-in proce-
dure included in this manual. If you have any questions, please contact the StopTech Customer
Service Department on (310) 325-4799 - extension 105, or you can e-mail directly to

Certain brake pad compounds make more noise than others. Proper anti-squeal shim plates be-
tween the caliper pistons and backing plate of the pad help to reduce the problem. Anti-squeal
lubricants are also available, to reduce some of the noise. The reality is that performance pads are
more prone to brake squeal.
