Brake master cylinder rebuild parts

[GraceRider]

Anyone know where/how to find just the seal cups or other individual parts for a brake master cylinder?

I have 2 sets of master cylinders to choose from for rebuilding. A Wilwood (1" & 7/8") and a Tilton set of the same sizes.

After pulling both 1" master cylinders apart, it looks like just the 2 seal cups may need replacing on each piston. I bought the $20 Wilwood 1" rebuild kit but if possible I would prefer to go with just the cups on the other cylinder(s) if they are available.

Thanks!

we had the same problem, but could not find just the specific part we need separately. after rethinking the situation, if one part had failed, the next part was going to fail sooner than later so we just did the whole rebuild on both for $55 after shipping.
