Reviews of OEM Volkswagen brake caliper

i have the same thing on mine, with rear disks & MKIV calipers, it stops on a dime

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.

Braking is sure, thanks to large four-piston calipers all around, though the pedal effort is not as progressive as I'd like.

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.

I had this problem with my 90 GLI. It was the parking brake mechanism on the caliper of the right rear wheel. It had seized, not allowing the caliper to release when I released the parking brake lever. I had to replace the caliper.
