[Biturbos4] Rear caliper pistons on B5

[northrup]

Jon:

Yes. I have run into this on my 2000 S4.  I started with one of those 
cheesy brake tools, and stopped for fear of causing problems.

I consulted my "mechanic friend" who recommended this tool:
http://www.thetoolwarehouse.net/shop/LIS-25000.html

Upon getting this item, i had the rear brakes changed out in minutes, and 
avoided any damage.   

There are some other sites who sell tools for the job such as this:
http://germanautoparts.com/displayimage.php?file=29702135N9M3

but they are single use, and i might want to use a brake tool on another 
marque sometime.

-wilson '00S4 + some other non audi cars that have brakes too.

I bought one of those pad compressor tools at Pep Boys and nearly ruined the thing putting so much torque on it pushing the pistons back in.

I did eventually get them back in and the new pads on, and I must say my initial experiences with the Mintex pads have been outstanding - much more even braking, less "grabby" than the stock pads, and significantly less brake dust.
