Master cylinder rebuild

[Weasel73240Z]

I'm trying to dis-assemble my master cylinder for a re-build. I've removed the primary pushrod, but I can't get the secondary pushrod to come out. Anybody know any tricks to get the secondary rod out? Thanks in advance for any help.

Assuming you have located and removed the two STOP BOLTS, #18 and #19 in Fig. 9.20, you can get the piston out by using a GENTLE application of compressed air to the front port.

A bike pump will probably do it, just make sure the other end of the M/C is covered over with a rag to arrest the projectile once it starts moving.

I have removed the stop bolts. I thought air pressure might be the way to go, thanks for confirming.

Thanks Nissanman, a little air pressure and "pop", the secondary come right out.

In your opion, is a rebuild better than getting a new unit?

Why did you choose to rebuild in stead of getting something like the bigger ZX master cylinder like some 280Z owners do?

I am rebuilding, as opposed to buying new, based mostly on how few (25,800) miles the car has on it. Sure, all new would be nice, but I don't think its always necessary, and my budget isn't unlimited ($10 for a rebuild kit/$100 for a new master cylinder). As far as going larger, I would imagine the stock 7/8" master cylinder is plenty for a 2,200 lb. car.
