[DML] Re: Shimmy While Braking

["Harold McElraft" <hmcelraft@xxxxxxx>]

Actual warping of a brake rotor is rare. There is usually some other 
issue such as uneven ware or run out - most common - and is a place on 
the rotor has worn thinner than the rest, for example. Other causes can 
be pad material or other contaminates on the rotor. All these problems 
are usually caused by defective system parts like a piston stuck or 
sticking in a wheel cylinder, leaks, grease, bad brake lines or 
incorrect pads to name a few.

Resurfacing the rotors (a cleanup cut or more, if necessary) will most 
likely solve your problem - however, if the system problem(s) that 
caused the rotor damage is not repaired your pulsing will return.

There is a high probability that there is a system problem that has 
caused rotor damage. I would check thoroughly all system functions and 
fix the faulty areas found, have the rotors turned by a professional 
shop with a certified machinist (I have found that these rotors are 
very sensitive and require the correct attention - be sure they are 
removed from the hub before turned) and put on new pads.
