Right to the point, thank you, I did something really stupid that you didn't mention, only use one push rod, go ahead and LOL, i'm lol now.

I'm trying to limit the "fluff" in my newer videos. It doesn't add anything but time to them. As a result, I find it increasingly harder to find good content that is worth posting.

My 69 eldo has dragging front brakes New calipers, pistons move freely, new rebuilt Delco Moraine booster master matched combination from reputable Cadillac restoration company I busted the master off the booster and it was definitely touching , I'd not actually pushing against it.. Do you know if those rods are adjustable? Can I washer the master? Or it needs to be inserted inside the female cup of the booster? So close!!!! Thank you Great video btw

Did you get it figured out? I just ran into the problem for the second time, you have to cut about 3/16 or 1/8 of an inch off and use a grinder or something to round the end again. I was seeing if anyone else has this problem. Apparently it’s common now that you say it and it’s happened 2 times to me.

It would have been nice to see you pull it out, because my push rod just falls out with a little cup on the end. I wonder if it's normal?!

[@antiqueautomotiveservice]

It sounds like you have a spacer stuck in the master cylinder. Some manufacturers will use a spacer in lieu of providing longer push rod. The spacer utilizes the short pushrod like the one shown in the booster here. And the spacer will be installed in the deep cup of the master. But it will just fall out if you let it.

Ive installed matching booster and master cylinder which came with the same hardware you have shown. Bled brakes and it still wont start braking until bottom of the pedal. Do they not make adjustable pushrod pins for these units? Im fairly certain my gap is too big, have no idea how i can close that . Iv even had a lower hole drilled into the pedal arm for longer travel still no luck. Any fixes?

[@antiqueautomotiveservice]

email me a photo of the pushrod, and one of the back of the master cylinder. Did you bench bleed the master before installing? [e-mail]

[@one_flight_away]

@@antiqueautomotiveservice yea its all been done by me and shop. Drilled lower hold in pedal, helped alittle but not great. Im thinking last option is shave down the longer pushrod pin to a better length with the spacer. Unless you can think of any other options or fixes. I put something temp spacing in the master cylinder and it stops like a champ just need permanent and safe solution.
