Help me identify a master cylinder please. - 06/18/11 11:23 PM

I got this master cylinder with some disc brake parts that i purchased.
I don't know if it's for a disc - drum, application, or for a drum - drum application.
Also need to know if it's for a power brake application, or a regular manual brake application.
A casting number on the bottom is 29861 which i'm pretty sure is a Raybestos number, and that seems to show up as MC36221, but i can't find out what it's used on.
Can anyone reference it for me?
Thank's in advance.

looks like a drum/drum. it can be used with drum/drum power brakes.

Look inside the piston recess in the back & if it's smooth like a tapered sewing thimble then it is a PB app & cannot be used on manual brakes as there's no groove to lock in the neoprene retainer. If it has a wide/shallow circular recessed depression about halfway down then it is a manual brake app as that is the groove that the retainer locks into but can also be used in a PB app since power brakes dont use the neoprene retainer on the end of the pushrod (assuming the bore dia is or close to what you need for your system which for the most part depends on the caliper type/bore dia/drum size/wheel cyl dia/pedal effort/feel desired etc)
