Hello. I was wondering if anyone new if the 71-76 88's had a dual diaphragm brake booster? Was it originally cadmium coated or black or other? The rebuilt units are black, but I can not find an original engine shot that shows the brake booster. Thanks for any response.

 

I am not sure if the 71-76 brake boosters were dual diaphragm. I own a 71 Olds 98, the brake booster is old and worn but I don't believe it was cadmium plated.

Fusicks sells rebuilt or new brake boosters for our cars. I am sure their products are "as original." They provide top notch parts at decent prices. You could always check their catalog or give them a call if nobody knows for sure.
