Weasel73240Z Posted January 16, 2008 Share #1 Posted January 16, 2008 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.

Nissanman Posted January 16, 2008 Share #2 Posted January 16, 2008 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.

Weasel73240Z Posted January 17, 2008 Author Share #3 Posted January 17, 2008 I have removed the stop bolts. I thought air pressure might be the way to go, thanks for confirming.

Weasel73240Z Posted January 18, 2008 Author Share #4 Posted January 18, 2008 Thanks Nissanman, a little air pressure and "pop", the secondary come right out.

TomoHawk Posted January 18, 2008 Share #5 Posted January 18, 2008 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?thxZ Link to comment https://www.classiczcars.com/topic/26779-master-cylinder-rebuild/#findComment-234577 Share on other sites More sharing options...
Weasel73240Z Posted January 18, 2008 Author Share #6 Posted January 18, 2008 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.
