[DML] Re: steering wheel shakes when braking

["Harold McElraft" <hmcelraft@xxxxxxx>]

If it wasn't doing it before it was stored (a long time?), you 
probably have some brake pad stuck to the rotor. There is much 
research out there that will tell you rotors rarely warp. Developing 
run-out or thick and thin issues and contamination from the brake 
pads is the most common. That's why turning them seems to help. You 
can take off the rotors and clean them with a rotor dress-up brush 
or have the machine shop do a dress up run on the rotors.

The cause can be from a caliper not working properly. A piston 
sticking or stuck and not releasing the pad the slight amount needed 
from the rotor can cause the problem by forcing the pad to stay in 
firm contact with the rotor - air in the caliper can cause that too. 
Sometimes stopping (not moving at all) immediately after the rotors 
have gotten very hot (like smelling them) may cause a pad to 
transfer some compound to the rotor.

In any event, you will need to remove the rotors to clean them ? 
that will be a good time to check everything for proper function and 
be sure the fluid is fresh, etc.
