Front and Rear Rebuild Kits
« on: November 14, 2015, 12:46:42 PM »
I bought an aftermarket complete front master cylinder, and it also includes an extra rebuild kit.  I need to rebuild the rear brake.

Does the front and rear master cylinder use the same rebuild parts?

I can't remember for sure but I think the piston diameters are different so the front cups and pistons won't work in the rear MC.
But id you look on the bodies of both master cylinders you may see the size of the piston bore such as 1/2 or 14 which would be 1/2 inch and 14mm. If that number is the same on the front and rear MCs then the cup seals MAY fit but may not.  Sometimes the size is not cast into them though. There are other sizes like 12mm, 5/8", 11/16" and such.
