trying to fix a mates magura, (04 style) and the symptoms are lazy pistons. On closer inspection it was in fact the master cylender piston that was stuck. Now after removing and cleaning the piston wont go back into the bore. After a phone call to tarty apparently the pistons can swell slightly when out of the bore. so i have tried the working piston out of an old brake of mine and that went in, all beit rather tightly. Now ive come back to it it is insanely tight much like the original. 2 pistons swelled or is it a fecked lever body?
