My brake booster just went out on my 75 280Z and I would like to replace it but suppliers are either out of stock, want me to send in my booster and they will have it rebuilt or sell me a newer modern booster. I want a replacement booster that has the vacuum port coming straight out that will align with the stock Datsun preformed vacuum line and not the generic one that comes out and then turns at a 45 deg. angle. I have already ordered two boosters  (Autozone) that are direct replacements and they show up with the vacuum port that comes out and then angles which is not what I have stock on my car. MSA, RockAuto, Parts Geek, and NAPA are all out of stock. Does anyone know of a good shop that just rebuilds brake boosters?

Here ya go...   https://www.thezstore.com/page/TZS/PROD/24-5231

if you have a 2+2:  https://www.thezstore.com/page/TZS/PROD/24-5232

Power Brake Exchange in San Jose, they also have a location in So-Cal, get them to power coat it too, they rust out fast.

Post a photo of your brake booster. According to the parts fiche, your booster should be like the 240Z/260Z booster if your car is not a 2+2.

If the booster's bad, what is the problem with sending it in to be rebuilt?

Called yesterday, the Z store MSA) is out of stock. I have the booster pictured on the right. Brakes were working just fine and then no assist, pulled hose and tried to pull a vacuum and could not get one, diaphragm appears to be bad. 

The booster is in really good condition and quite rebuildable. I want to send it in to a rebuilder myself and get it returned to me without going thru another set of hands. I want to get this car back on the road.

Heyitstrama, this is just what I was looking for, I will give them a call, thanks.

Yes, I agree. Deal with a smaller rebuilder. Ask for your original back, no exchange

Power Brake Exchange. Great people.

I think another forum member recently had an issue with his booster that he got from a supplier, unfortunately they sent in the old one as a core exchange.

 

makes me even more inclined to say rebuild is the way to go.

Plus 1 for Power Brake Exchange. I sent them 3 and got all three back in less than a week. I had all of them powdercoated and they were beautiful. 

Sounds like you have your answer @Cruzzar...  keep us posted and maybe send over before/after pictures?  

 

I had good luck with Cardone via Rock auto, about a 2 week turn around
