Nova master cylinder push rod question

FLEMING · 06-14-2012, 09:50 AM

My brake pedal on my nova has always had a lot of travel in it before you actually got any pedal, no matter how many times I bled the brakes or even put new mast. cylnder it always felt the same..

While working on it last night i have the seat out of it so I can get under the dash pretty good I noticed you can adjust the brake pedal to master cylinder rod.. So I took it apart and ended up moving it about 1 1/2" and now you almost instantly have a pedal... I ran the jam nut up behind it is it that I adjusted this?? Now the clevis is about in the middle of the treaded part of the rod...To me it seems like a no brainer and I wish I had done this a long time ago.. I just want to make sure I am not screwing up anything.. lol

As long as the brake pedal push rod cannot fall out of the back of the master cylinder, it is fine. If you still use the brake lights, the switch may need to be screwed out more.

Make sure with you foot off the pedal that the master cylinder plunger is not depressed at all. There should still be some "slop" in pedal movement before the caster cylinder plunger is depressed.
Secondly, make sure you have the derby hat shaped steel retainer sandwiched between the master cylinder and the firewall, protruding under the dash, to keep the pushrod from coming out.
