I have had brake fluid squirting up and comming out of the master cylinder and running onto the area underneath. Only found it too late for the paint. The brake experts wont help or have no idea. All sorts of sugestions came from this forum so I decided to buy a new master after preasure bleeding and vacume bleeding, as well as putting on a new PBR CAP SEAL! Now I read that the cylinder I picked "Protex" after being assured they were good, is not recomended as they have problems. SHIT AND F..UCK ME! Anyway you may have the same gremlin as me. If this new Protex cylinder is a fail, after I bash my head on the concrete floor, I will try for a rebuilt origonal unit worth a bazilion dollars. How the hell do brake parts that are new be crap? How do they make it into the country. On the subject the Protex unit i bought would not let the fitting screw in far enough to seal the lines. The thread in the master was not tapped deep enough and so the fittings had to be changed. Cut the lines and add in new different fittings on a short new piece with a union. Dont buy Protex would be my recomendation!
