My brakes stopped working properly not long ago. It took an excessive amount of effort and time to stop the car (the green one ). I brought to a local mechanic that does brakes, tires, suspension work, who I'm usually quite happy with for those things. The master cylinder was leaking, so he replaced that, but that didn't fix the problem, which we learned a couple of hours later, so we brought it back. They troubleshot some more and determined it was the brake proportioning valve (called brake pressure regulator in the Bentley I believe). They had said they couldn't get the part, and so they bypassed it and the brakes seem to be working properly right now. I have read in the forum a few posts regarding this part, so I'm thinking we probably should replace the part. I know I can get it from worldimpex. (I didn't know that at the time I spoke with the mechanic). My question is, is it OK to drive for a while with it bypassed? This mechanic doesn't have a lot of VW experience, but plenty of brake system experience with other cars. But maybe he doesn't ubderstand this part, if it is kind of VW unique. If I get the part, how hard would it be to replace it myself? (I read what to do in the Bentley, but not sure I understand how to do what it says.)
