Hello. My brake system is defective. More precisely on the right rear axle brake fluid runs out. I suspect that the used brake caliper recently installed by the workshop is defective. My question is actually, what was installed at the 1,9 TDI year 1993, Limosine with disc brake on the rear axle for brake caliper?? I unfortunately did not find it in my clever book “Now I help myself”, and I did not find it here when searching. I had the car in the workshop three (3) times as far as the brake is concerned. And also at the pickerl three months ago something was done on the brake. Oh yes, there is a girling on the front axle. Please answer. MfG
