i have over extended my rear hayes nine xc lever this weekend...shattered the snap ring and retaining washer holding the push rod to the master cylinder...

i am wondering what the easiest way to repair this...can i simply remove mc from lever and place new washer and snap ring over the push rod? is there no reason to even remove mc, can it all be done with lever assembly mounted on the bars?

lastly can i just buy a snap ring and washer or must i purchase a complete rebuild kit...?

over and out,
adubb

OK, I'll do all the work for you.
Here is a place to order the parts. The whole kits and kaboodle.

Notice the washer the c-clip holds in place is actually flat.

no fluid loss... so i put a new retaining washer on the end of the pushrod and then "snapped" the c-clip in place...no bleeding or removal of any parts - the only thing that i did was rotate the lever up for accessibility...easy fix...
