I know the pushrod is held in with that tiny rubber bushing & thought maybe a few taps on the master cyl. with a hammer while holding the pushrod would've done it, but I've destroyed my old cast iron master cylinder (CAST IRON CHUNKS EVERYWHERE) beating the daylights out of the master, to pop the pushrod out of the back of it & the rod won't come out. WHAT AM I NOT DOING CORRECTLY???? Please advise!!!! Thanx!!

Remove the 4 bolts that hold the master cyl to the firewall and then put something between the master cyl and the firewall and then pull up on the brake pedal and the pushrod will pull right out. Remove the brake light switch if you think that you are going to damage it.

Otherwise cut a short block of wood a little longer than the length between the base of the m/c and the p/r hole and use a screwdriver in the hole over to the block as a lever to pop it out. You're going to ruin the rubber bushing but Mancini has them for a couple bucks.

Use a long bar of some sorts through the brake rod hole and place under the jack body, then make sure the piston of the MC doesn't pull through the hole and jack it up. The force of the jack should pull the piston off the brake rod. Make sense.... Mini hydraulic spreader... hahaha Last edited by Cuda340; 08/04/10 03:50 PM.

I hammered on the mtg. face of the m/c so hard that I broke the mtg. ears off the m/c. The sucker "ain't" coming out...LOL!!...with normal methods.

That little grommet rides in a groove inside the piston and some times it can be a real bear to get it to pull out. Hmmmmm, How to build a better mouse trap.....?

It tool a couple of pops but it came out without smoking the casting.
