See posting #9 in this thread:

Since that thread ran its course, photo*ucket decided to be annoying. All of the original pictures have been restored and are visible if you just scroll down far enough.

I believe 63-64 front wheel cylinders are 1 3/16" Are they "bolt-on" items with no modification required?

As I recall the '63-4 wheel cylinders attach to the brake anchor pin. However, even if that's incorrect, the way they attach is not compatible with the two-bolt mounting of the C1 wheel cylinders.

Edit: Looks like my memory isn't as bad as it usually is:



With some cleverness this could probably be made to work. There could be an issue with the alignment of the anchor pin and the web of the brake shoes.

NAPA numbers are 34151 and 34152 if anyone feels adventurous.

See above, Bill. I just edited my previous posting. My answer is a definite "maybe".

But if you don't mind firing up your angle grinder, what I proposed in the other thread works just fine, guaranteed.

I love a challenge, but with 4whl discs I don't have a need... BUT I do have oversize single piston front calipers (now if I could only remember where I got them from... )

I haven't seen it metnioned, maybe I missed it. Has anyone tried honing and rebuilding their wheel cylinders? I never buy new wheel cylinders if I can rebuild them.

unless badly pitted, i always rebuild: even disc brake caliber bores.

and, there are places the wheel cylinders can be sent off to to be rebuilt.

I took an old worn out pair of 1.125 cylinders and machined them to 1.187 using my Sunnen Rod machine, many years and many thousand miles later
they are still in service.

I have also honed and rebuilt many master cylinders and wheel cylinders over the years with excellent results. Brake calipers as well. Very cost-effective and productive.
