Cannot Remove Brake Pushrod From Rear Piston

[boboh1]

Replacing my brake master cylinder. When I removed the old one the pushrod would not release from the pistons. I got this left to remove but it won’t budge. Is there a trick to this?

Do you have any other photos from an angle from in side installation in the firewall?

pb buster let it soak. Do have a vise?

Clamp it in a vice, the ROD. Leave just enough room for a pickle fork between the piston and rod. One wack ...

Clamp the rod in a vice with about 1/4 inch of space to the piston. 2 large screwdrivers one on each side and it will pop right off.

Is that in the "hood" version? LOL

Thanks for all the advise. I do have a vice. Man it is in hard. All my other cars in the past the rod just slid out easily. Now I hope the bolts can be pounded out from the old MC

If you are reusing the studs, put on nuts to save the threads and tap them out with a hammer. Just tap them into your replacement MC. I had to use JB Weld to secure them into a new MC with larger holes. Worked well.

The "trick" was to pull it out while the master was still on the car. Do as Dadsbee says.

You can put that piston on a hard surface and whack it with a hammer, it will break.

So, were you successful getting your hard rod out of the hole ? And, when pounding the bolts watch out for your nuts.

#10, you should have did it when it was still in the car, you still can.

How is the firewall going to hold the piston in?

^^^ The only thing holding the piston in on a manual master is a little tab screwed in place. Not gonna hold a stuck rod... just gonna bend out of the way.
