The 1 I got on it isn't the spring clamp. It has a bolt and double eared piece that is about 3" long. I cleaned it off good this morning and drove it awhile and there is fluid back on the bottom of the master cylinder, I did have brakes when I drove it. I have another master cylinder now so I'm going to change them out. I just hope this fixes it. Ronnie




Take the cover off carefully and see if there is fluid on the top surfaces , also those surfaces are usually not smooth, have alot of scratches and will leak , I usually lap mastercylinders , especially rebuilt units , before instal to get a smooth sealing surface .

Also check that the lines are tight , if they are leaking you will have fluid under the master .


How do you lap a master cylinder lip?

With a lapping block and lapping compound. Never did it but I'm pretty sure it's like lapping a gate valve disc.
