When I found a place with parts for that '59 Bnedix what I discovered was that the place in California that sold me the rebuild kit also did the actual rebuild for only about $100 more. When it comes to something like brakes, if you are an amature mechanic like me I suggest you have yours professionally rebuilt. You don't want to find out the hard way that you didn't do it quite right.

Mine looses its pedal when it sits a couple days or after shutting it down. No fluid loss anywhere. Thanks for any advice or help. | | | | | Joined: May 2005 Posts: 8,878 . | | .

I've never done anything like that before but it was pretty strait forward. I think the price on a rebuilt was about $260 and I bought a kit for about $125. Mine uses a large leather washer in the vacum pot. That would have cost another $50.00 but I was able to clean mine up and make it work. I bought my stuff from Reman in Atlanta. I don't recomend them. They lost my order and then shipped it with missing parts. The parts they left out took over a week for them to ship. I think it was about a month before I had what I needed to get it done. | | |
