Why are VAG rear calipers crap???

[pimpdriver]

Hi

i had a new rear caliper in January 2008 and it has already siezed. I had both rear calipers deseized in April 2009 and the handbrake has approx 4" of free travel before it moves the calipers (ie slack cable) . Both cables are fine.

Speaking to my mechanic he said late 80s early 90s VAG rear calipers always seize (the reason why people put golf mk4 calipers on golf mk2).

Can any later audi calipers be fitted to the rear of my 1990 audi 100 quattro???

When you re-fitted them did you wind back the cylinders?
That caught me out the first time.

Hi Karl

it wasn't me that did the work but the guy who did is very experienced with VAG cars.

The brakes were fine for a couple of months.

The procedure vag80 dave posted is the same as the link I put in so I will ask my mechanic to do that.

Maybe this can help ...something new I did up a few months ago..(ok I actually took over 2 years of research and development to make them!)

This was a completely new design of the older VAG calipers I did....based on the current GOLF or AUDI A3, A4 , A6 ...
This is the Quattro version (with 38 piston)



Here one of them mounted on an Audi 100 quattro.


These things have dual o-rings for better water intrusion....I designed them to last A LONG TIME!

And NO they do not cost an arm or leg...I offer these at less then 1/4 price of VAG...plus I throw in new brackets and pads.

Where to find our more about these things?-->

hmmm! those handbrake quadrant seals look like a possible for my 100t, it failed the last m.o.t. on a siezed rear caliper....(before my time mind! i'd have sorted it before the m.o.t...)
will have a look!
