    Good afternoon. I need to look into rebuilding my 70's era Atwood surge brakes.

    My question is weather or not rebuild kits are available for the master cylinder. You can see in the pics that it was pretty much a mess when I got the cap off. The rubber plunger is basically melted. I'm open to just replacing it, if a direct replacement is available.

    Ill probably need new wheel cylinders also, but the lines are in good solid shape.

    Looking for advice on how to handle it if I can't rebuild/replace.

    There should be a part number cast or etched into the side of that master cylinder. Contact etrailer.com to find a replacement. You may need to provide measurements, length, distance between bolt centers, etc.

    From the looks of that master I would go ahead and replace the wheel cylinders. Rust in the fluid will cause leaks.

    Thank you Steve. I will replace the wheel cylinders as well. I hope eTrailer has what I need. I was going to check with Napa also.

    Boy that sure looks like early 60's Ford master cylinder.

    I would also check Eastern Marine. They cater to the boat trailer folks and a lot of boat trailers use hyd. brakes.
