Interchangeable brake booster?
I wanted to know if you can swap the two different common types of brake boosters on 81-82 trucks, I have the shorter width, larger diameter booster on my truck, which has gone bad, and a good larger width smaller diameter booster on hand. Anybody know of any differences that would make them non-interchangeable?

Re: Interchangeable brake booster?
The 2 types are HD (dual diapram) and non HD. If I remember correctly the rod is different lengths.

Re: Interchangeable brake booster?
Well, I was wrong on the diameter, they are both the same. The good other one is thicker, I'll bet its the dual diaphragm. It came off a suburban. I lined them up side by side and there was no noticeable difference in rod length in this instance. I tore it all down and removed the old one, I have the new one loosely on there, we'll see how it all runs when everything is tightened up.

Re: Interchangeable brake booster?
All the burbs I have ever worked on or took apart had HD boosters, did you swap rods from one to the other or use what was on the booster?

Re: Interchangeable brake booster?
It swapped over fine, I used the burb's rod, bolted in like it belonged there. I am still unable to make this turd idle, keeps dying out.

Re: Interchangeable brake booster?
That's weird. One time I had a truck with the light duty boost and put the HD booster on it. Used the same rod and it worked just fine.

Re: Interchangeable brake booster?
That was the case with mine, bolted up fine.
