attempting to rebuild the master cyl.
i know it is easier to rebuild while still on truck,
but tried to wrench the nut off of the back, and could not budge it.
so, i took off cotter pin and bolt off the front where the linkeage is,

only to find i cannot get the piston out.
i tried to hammer it out with a drift from the back,
but it is not moving and i am not sure if this will damage any parts on
the inside.
if i continue the hammering, will i break anything?
anyone have any suggestions?

get the nut off the back in order to move foreward, but i cannot seem
to budge it i even heated it until it seemed toshoot fire thru the top
into the cab, and then i got worried and put some ice to the bolt part
but it still won't budge.
even with a cheater bar.

Well it sounds like you probably already have done some damage.... The
guts of the cylinder come out the end where the push rod goes in. There
should be something like a large c-clip that holds everything in. When
you take that out all the guts should pop right out as there is I think
a spring in there that will push every thing out.
If you remove it from the truck all this should be evident from
inspection.

You should also be able to just buy the MC:

Some older master cylinders have a little plug screwed into
the middle of the barrel. The plug is actually a retaining
pin extending into the cylinder to keep the piston from being
pushed out by the return spring after assembly. The plug
must be removed before the piston will come out. HTH.

Good luck.

Rodan.

wow, thanks so much for all your suggestions-

i had to go buy a 1 1/2" socket with a 3/4" drive set from harbor
freight.
then i had to tighten the nut to break the seal. then wrench it off.
after that i could unscrew it by hand.
i did get it all out the back side of the cylinder and ran a hone thru
it.
after an all day dissassembly, the clean up, and reassemble was quite
quick.
alas i have conquered the little bugger.
thanx again!!!
