My 99 R129 brakes are audible (groan, not squeal) and grabby at low speeds when wet and cold. Very difficult to come to a completely smooth stop, but not a safety concern. Without taking anything apart - things look fine. I am thinking PO neglected fluid changes or let pads run too low and I have pitting on the front caliper pistons. Before I start disassembling - is this behavior normal for R129?
