Re: [AMC-list] Need help with master cylinder removal 1965 American, non power brakes...

Nope it's not uncommon, at least in my experience.  Also, if the push rod is not the SAME EXACT length as the old pushrod, the little bleed hole(s) in the master cylinder may not be uncovered when the rod is retracted (it won't fully retract if it's too long) and you will never get a firm brake pedal.  So make sure the new pushrod is exactly the same length as the old one.  Normally, the master cylinder vendor advises you to bench bleed the master cylinder before installing it.  It eases the process of bleeding the brakes because then you only need to worry about the air in the lines, and not air trapped in the master cylinder.

Tom, 
 
Thanks for the reply...I got it swapped out but had to change the pushrod from one master cylinder to the other but now I have absolutly no pedal at all.  Is this normal when a non power brake master cylinder is changer ?  I realize that I need to bleed the new master cylinder but shouldn't  I have at least some pedal ?

OK, that would suck :-)


On my 63's they just "come out". However, you have to pull! There's a spring
clip in the piston part that grips the pushrod.
