73 Master cylinder/brake booster combo
Anyone have any advice/history with a good replacement for above, my master is leaking into the booster,,,,I guess I have to figure that after 40 something years had to happen.  Any suggestions on a replacement?  Of course I want easy install and good fitment along with good performance.  thx for the advice.,,,,Lou

Officer: Now son take care and keep it between the ditches.

Me:  But officer, I do some of my best driving in the ditches!

I sent mine in for a rebuild through Rockauto.com. It was around $115 for both to be rebuilt. Sent it to a place down in Texas. I should have it back next week.

Buy the rebuild kit. Simple procedure and a guaranteed fitment.  Ed
I got mine rebuilt by Booster Dewey and they did a fantastic job, cost was $135 plus shipping!

I do not have the name in my mind right now but they are in Oregon. Have lifetime warranty and I am told are very good. The master cylinder for the PB is if I remember correct 15/16" dia. and manual is 1" dia.. You can rebuilt the master cylinder yourself unless it is pitted bad and needs a sleeve. If you are trying to keep original you need to send to have rebuilt. If you buy over the counter they are not made the same as original.
I have been driving my 73 with bad booster this year until cold weather then will send to Oregon for sure.

When a man is in the woods and talks and no women are there is he still wrong??
David, is this the one?

Booster Dewey did mine.

Works great, if you want it to look perfect and the shell is pitted be sure to pay the cosmetic up charge and they will bondo it before they paint it.
Back in 00, I had an Opel booster rebuilt by a place in California called Vanco. Nice job and decent price, better than an Autozone replacement, for sure.
Yes David and Don C, Booster Dewey are the guys in Oregon!

Kevin, I was just curious if you ever got your brake booster back and if you’re happy with it? I’m considering sending mine thru Rockauto too. When I go to their site it only shows for Prior part #2510237 with front disc, rear disc, $99.99 Mine is front disc, rear drum. Is this the same part # that you used? Thanks Ryan.
