Brake caliper OEM Volkswagen or OEM Porsche

I had a MK3 GTI VR6 that that happened to. I went thru several e-brake cables. Finally figured out the calipers were steel and they would seize up from rust. I swapped them out for some aluminum ones from a MK4 and the problem was solved forever.

I'd go with Porsche calipers on stock rotors, which is what I run. MUCH improved pedal feel and modulation, ability to swap pads without taking the caliper off, and more pad options.

I've got an Audi A4 Quattro that I DD, Autocross and teach HPDE ( Track Days ). Originally I tried the TT carrier / A8 rotor (312mm ) upgrade. I later switched to Porsche Boxster calipers because I was getting pad taper on Track Days.

It's a known problem with knocking brakes on the off rear of B6 passats. To fix, remove the caliper, pull out the top and bottom did pins and half fill with a heavy grease or copper grease into the holes the slide pins slide on, refit and no more noise! Just did mine last week.

Rear calipers are a Porsche 944T, the disks in a VW Corrado / Golf G60, 280mm, 274mm lowered to the clamps are anchored with an adapter for Grinling54, is to lower a bit with the grinder, but it is simple

those look old i have an 83 and mine look different

I currently have 12.3" Audi TT rotors with Porsche 911 (996) calipers. Those brakes works fine, but I want smaller brakes so I can fit 15" wheels.

It takes a larger master cylinder to push more fluid to four pistons. The surface area of all 4 pistons pushing on the disc is slightly larger than OE. A larger (thicker) rotor is being used and I'm not sure how to calculate that into the equation or if that's even important. Regardless if you have the oe mater cylinder using Porsche 4 pot calipers you will have to get a larger master cylinder.

I put a set of GLI calipers & rotors on when someone else upgraded. Really didn't notice a big difference, both in weight or stopping power.

ultimately you will need a new caliper, because the parking brake mechanism ins't rebuildable by itsself. It's a common vw problem, actually, both my parking mech's are seized. just don't use the e-brake. and don't buy a rebuilt caliper - they never last.
