I would like to have my original disc brakes m. Cylinder rebuilt on my ‘68 as it seems to be leaking from the rear compartment and overfilling the frt.
Does anyone know or have experience with having theirs rebuilt ?,,,,, Doug

Here is where I had mine done. http://whitepost.com/brake-sleeving-rebuilding-services/

May just need new seals, Take it apart and check for corrosion in the bore. If it can be cleaned up with a light hone,
Why not buy a rebuild kit and do it yourself?
If it's pitted beyond a hone you will have to sleeve it.

You can DIY providing the main bore isn't grooved or damaged. Buy a Wagner kit, clean, install kit, bench bleed, install, bleed all 4 wheels.

Thanks peeps
