Last weekend while down in St. Louis for my grandmothers 90'th I was cruising around in my mom's 855, and once the brakes start getting heavily used and hot, the backend vibrates like someone started pumping some 15's behind us

I have heard and felt squeaks before from loose shim and whatnot, but nothing like this. The rotors are fairly new and in good shape.

At any other time the brakes are fine. Its just after you have been stomping on them a lot doing down the hills and other places in 95F temps that I have felt this come on.

what kind of shims were used?

and if normal did you cut the shims as per on the main vs page as from what they say and i'm told it does help stop that vibration

otherwise i can get ya new ones pre cut

Rear brakes and rotors were installed my our indy mech probably a year and a half ago. So far I have only done the fronts on this car. Can't blame this one on me yet

I am putting metal master and new brake lines in the car one of these days. I will do the shim thing then and see whats up.

I would use factory pads ..but it sounds like you may have a caliper hanging up or getting tight...looking at the rotors you should be able to identify that by the color

yeah, the shuddering is usually worn pads....DUMP THE METAL MASTERS!! go with OEM pads bud, you'll be much happier with them...my brakes are actually doing that same thing right now, just waiting on my Brembo/OEM pads kit....

Just for the rears? or overall in general? I have been loving how they act up front for the past 4-5 months.

One way to diagnose the problem, if you're able, is to remove the rotors, sandpaper the surfaces well with medium emery cloth, and give it a good try. If the brake judder disappears for a while, you know that those pads are transfering material to the rotor surface. The probably reason is that the pad material is inadequate for heavy braking, melting, and depositing material on the rotor surface. You probably can't see it, but it's there.

I like Mintex pads on the rears.

i've been using OEM all around....dont do much hard braking unless it's emergency braking or whatever.....
