removing master cylinder? 54 poncho

I am positive some of you have done this before, but I just can't get it loose to save my life. I removed all the lines, the 2 bolts that hold it down and the bolt through the plunger but the body of the master is still connected to the pedals. It looks as though the pivot point is a stud bolt with no nut on theback/inside. Does anyone have any guidance they can hook me up with?

 

If it's like the Chevys, then there is a set screw going into the casting part of the m/c where the pedal pivots. The set screw is perpendicular to the "axle" of the pedal, and usually points toward the front of the car. This screw goes down into a groove on the pedal's pivot axle, holding it in to the m/c. I think there were several GM's that used this concept. Not sure about Pontiac, tho.

Do the Pontiacs have a 2pc pedal like the chevys? If so, you can usually take the top section of the padal off. (The single bolt going thru it near where the pedal goes thru the floor.) Then you can let the bottom portion "fall" since you already disconnected it from the plunger. Then you can take the m/c out with the bottom half of the pedal still attached. At least you can on a Chevy...

hope this helps a little.

 

What Slide said. It's a ***** of a job. There's a thing that looks like cross inside the front of the MC. If you're like me you strong armed the ***** and broke it. It's being reproduced but it's way expensive.
Good luck.

 

Thanks guys, I will take a look at that, I tried to reference my manual, but the diagram i there is set up wrong with the pushrod inserted in the ont...strange.

I noticed new MC s are like 200 USD! WOW! looks like I will be very gentle.

 

So, in case anyone is interested, I needed to take the bottom half of the pedals off like Slide suggested. When I got the master and the pedal arms out, it looks as though the pedals are pressed in, there are no set screws anywhere unfortunately.

Now the master is rebuilt, and ready to go back in.

Thanks for the help.

That's pretty wild. Seems like there would have to be a snap ring or sumthin. Oh, well, glad you were able to take care of it!
