Most vw bug masters come with a residual pressure valve for drum brakes inside , if your using disc on all 4 corners you need to remove it and add 2 lb residuals outside , one for front and one for rears , the stock residual valve keeps too much pressure on the calipers , drums require a higher pressure to overcome the springs.. it could allso be a bad hose if your calipers are sticking and not letting the fluid go back towards the master , Let me ask you when you get the caliper stuck have you opened the bleeder and see if the caliper frees up ?? that will tell you if something is keeping pressure on them ?? i have disc on all 4 corners with a stock master and external residuals and mine work perfect ... let us know ??rbeeson said:
