Brake master cylinders replacement

[OR75]

My J still has its original brake master cylinders: Paramount VI-15-625CH

One of the cylinders is leaking. i am hoping overhaul with new o-rings will take care of the leak. But just in case the cylinder is not overhaul-able, are they alternate cylinders to replace the original one ( with same footprint)

Gerdes A-110-37

Cleveland 10-49

Cleveland 10-24D

The numbers above are from memory, so check the manual. I swapped my originals out last year. If I remember correctly, they are susposed to be swapped out in sets.

thanks. those are the P/N i came across in that parts catalog as well.

I believe the cleveland 10-49 is just a rebrand of the Gerdes A-110-37 as Cleveland bought Gerdes.

I figured they would need to be changed in pairs

Yes the cleveland and gerdes are the same cylinder. Both them and the paramount are 5/8 diameter bore. The 10-24d is a larger diameter bore, but still a drop in replacement. It also has a external spring instead of internal as the others do.

I have spare paramount cylinders if you need. They are serviceable IE guaranteed to work.

Any chance you still have the serviceable paramounts?  I got one that looses pressure when slowly depressed. Trying to avoid the $1700+ kit from Lasar. 

Thanks
