Braking Question

[Todd Young]

I'll second that. Also wouldn't hurt to just give the brakes, both front and
back, a good "going over:"
The '92 100 series does not use the "bomb". Chances are you have multiple guide
pins that are rusted, and therefore are not getting full braking power. Don't
get too depressed though, the rear caliper mounting assembly, minus the
caliper, is only around $90 at the dealer. I'm willing to bet you have
rusted/frozen caliper pins.

First thing to do, start at the front, and take the caliper assembly off the
pins and try to remove the pins, if you can get them out, chances are they need
a new coating of grease. While you have the front apart, clean everything up
with brake cleaner and then install a good set of aftermarket brake pads. Less
dust, better braking. I'm using Bendix pads up front that I got from the local
foreign auto parts store. After you are done in the front, go to the back and
do the same. But be prepared to have to leave the car on jack stands while you
run to the local Audi dealer for the caliper mounting assembly, as you might
break a pin or two trying to get the rusted ones out. Also make sure your
emergency brake levers move freely. If the E-brake levers are frozen, then your
rear calipers are not properly adjusted. The ONLY way to properly adjust rear
disc brakes is by constant use of the emergency brake. If the levers are
frozen, you may be able to work them loose temporarily, but chances are they
will just freeze up again in a month or so. Best bet is to just get rebuilt
calipers.

I drive a '93 90S, and after working on the brakes, front and rear, and getting
everything lubed up right and the e-brake working correctly, it stops great.
The Bendix pads work fine when cool, work great when heated up a little, feels
like someone threw a boat anchor out the window.

Oh, and if you have no idea what to do with the brakes, then ask someone who
has worked on brakes before, or take it to a professional, as you don't want
your brakes to fail.
