Are these easy to find ?
I ruined my old one,,,when i removed the pushrod from my old master cylinder.
I need to put a new one on,,,,,
in the past i was lucky to have one in the replacement MC....which was not the case with the MC i just got.

I compared an OE one side by side to a piece of vac line & they're identical ex for the OE one has a groove cut lengthwise on the outside that does not affect fit or function. Dont remember what size of line, my parts house just snipped me off a piece.

I got a dozen of them from him also a couple years ago. They DO NOT come with rebuilt masters!


The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

Ever had the push rod come out of the master cylinder on a 10 sec car. If the grommet is not there, the only thing keeping the pedal from coming back and disengaging the m/c is the flimsy tab used for the brake light switch. Pretty helpless feeling going for the pedal and the rod is against the firewall. Destroyed a $20K car over that rubber grommet. you need it. I also make a positive stop for my brake pedals now. Not too hard to get your foot accidentally behind the brake pedal when going to tag the brakes@ 135 so as not to hog the finish line.
