Please, somebody has to have an answer. I found out the hard way that I have to use my original push rod for my new dual bowl master cylinder. Both my old and my new pushrods have that stupid little clip that is locking them into the master cylinder. I have tried the screw driver & needle nose pliers trick, and I've tried the slidehammer trick, both to no good. Does anybody else have an idea as to how to get the pushrod's out? Thanks, Michael
No, unfortunately it's not. I got that out with a flat head screwdriver. At the end of the pushrod inside the master cylinder, there is this really strange little clip that holds the pushrod in. I can't get it out, I need to get both the new pushrod and the old pushrod out of their respective master cylinders, and on top of it, my car currently does not have brakes and I am supposed to be starting a job sometime in the next couple weeks.
I pulled mine out of the parts bucket and it had the original pushrod in it still. I put the master cylinder in the vise and pulled hard on the pushrod and it popped out. It looks like it has a compression type ring on it that closes up when you push it in and opens once inside where the larger diameter is. I don't know that mine is original as I bought the car used but that is how mine was set up. Sorry I could not be more help. Hopefully someone else has some input for you.

Well after all our efforts, my original cylinder is extremely beat up, and I've even broken part of the piston. So, I've decided that to get my original master cylinder's push rod, my metal teacher and I are going to cut it out. I'm still at a loss on how to get the pushrod out of my new master cylinder. I don't want to, nor can I afford, to break it's piston.
Print Dad, I always say thank you to my teachers. And we were victorious with cutting my old master cylinder's piston in 2. Here are pictures of the 2 halfs of the piston, and the pushrod after I sandblasted it clean.
The pictures are great - nice job. I am glad you thank the teacher.
What you need to do is put the master in a strong stable vice.
Hold it on the end (the part that bolts against the firewall)
The put a ratchet handle through the end of the rod and pull like heck.
You will not break the rod. The clip is small. See the ridge inside the piston? That is where the "spring clip" opens and catches.
If you can't just pull the rod out, you will need to make some sort of leverage point.
See if I can explain this - -
Clamp the master in the vice with the rod facing you. Now run a bar or ratchet handle through the open end of the rod. Now you have the bar running parallel to the back of the master. See if you can put 2 blocks of wood between the "bar and the face of the master. Now take a wedge and try to force the rod towards you.
One good tug will pull it out. If not you need to make a fulcrum point so when you push on a pry-bar it forces the rod outward.
Don't squeeze the master by bowl, could caaue problems
I got it!!! Print Dad, I took your idea and modified it abit. I used a pair of pliers, my jack, and my friends jack. I then held the master cylinder with the pushrod sticking up. I put the pliers through the pushrod, and put a jack on each ear under the pliers. Then I just jacked them up evenly and it popped out.:yelpleased:
Thanks. I couldn't have gotten it without you guys. And I thanked both my teachers that helped me several times. The master cylinder is now installed, and Saturday my friend Eric and I are going to bleed the brakes.
