1969_Mach1 333 Report post Posted August 23, 2016 I need a new front seal for the Bendix brake booster in my 1969 Mach 1. The booster was rebuilt about 20 years ago, works fine. But, I noticed when recently replacing the master cylinder (again) that the front seal no longer fits snug on the push rod. The front seal is easy to replace. Where can I find a front seal for this or some kind of rebuild kit that contains the front seal? Last time I had this booster rebuilt is was a nightmare. Took a long time. I couldn't take time off from work pick it up when I was told it was ready, so my father picked it up. They gave him a different booster because it actually wasn't ready, he didn't know. I still had to take time off from work to straighten it out and get mine back. Yeah, since then, I am skeptical of these "specialized rebuilders". Thanks for any help.

1969_Mach1 333 Report post Posted August 24, 2016 Thanks, but no. That is for a Midland brake booster. Bendix brake boosters don't use that. Quote Share this post Link to post Share on other sites

Brian Conway 264 Report post Posted August 24, 2016 Kinda curious as to what front seal you are are referring to ? By your description it would seem your are referring to the interior diaphram/bellows that is the size of the booster itself ? Pretty much what a rebuild is all about. The booster in the picture, Bendix 6945, can be gotten at NAPA, ebay or most auto parts stores. Somewhere around $150. Brian Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted August 24, 2016 There is a seal behind the paper you have at the push rod where the master cylinder attaches. Without a seal there, you will have a massive vacuum leak. It's easily removed and installed. Mine no longer seals around the push rod very snuggly.

1969_Mach1 333 Report post Posted August 24, 2016 Sorry, my bad. May check this site out http://harmonclassicbrakes.com Nice site for brake parts. I might call them. Their website doesn't show Bendix parts or brake boosters. Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted August 24, 2016 Sorry, my bad. May check this site out http://harmonclassicbrakes.com Thanks for the link. I called them. They have a refresher kit for $19 that contains that seal. I ordered 2 kits so I'll have a spare. 2 mwye0627 and Raven R code reacted to this Quote Share this post Link to post Share on other sites
