[T3] boingy boingy boingy when I brake

["Martinez, Leon" <martinezl@ftscpac.navy.mil>]

I had the boingy thing when I braked and it was caused by a warped rotor
that I swore was not warped, it happened to my square and other cars. I
would
turn the rotor and eyeball it and it looked smooth and straight but it
retained it's
boinginess until I replaced it, never had that problem again. I also
replaced others on another car (Volvo) because of deep scratches, the new
one was warped; my brother (worked at autoparts store for 15 years)  told me
that some Taiwan brands had some metalurgical problems; they warped during
cooling or the metal was so soft and densities were not even that they
warped prematurely.
Watch out for the cheap stuff, get quality parts if the rotor needs
replacing after
turning or cleaning rotor does not do it. Replace all old brake fluid, you
will be
surprised how much evil dark matter you can remove from the plumbing; on
mine I had rust and black solids filling my lines, this was causing my brake
cylinders and calipers to stick. Stickiness and boingy boingy boingy is all
gone
and my brakes are tight now. Care like this should be taken on all old cars
because time, weather and the previous owners can take their toll.
By the way, I got my original spare "MADE IN GERMANY" tire from the
junkyard, it even still had some rubber "hairs" on it. I hope you have the
same luck getting one since the tire guys pissed you off after throwing
yours away, You can get one off a Bug also (at the junk yard).
