Brake booster rubber boot/bellows - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**StingRay** · 06-28-2003, 12:44 AM

A couple of brake boosters I have need the rubber boot or bellows on the input side push rod replaced and for the life of me I can't find any info on brake boosters anywhere. The two I have are the Delco units from 72 that have the gold/silver plating and the plastic deally sticking out the back that the boot covers over. The older boosters (69-70) that are not plated but rather in black paint don't seem to ever need a new boot and it is different than the newer 72 type units use anyway. Does anybody know where to find these elusive rubber parts? I have also noticed that there must be a foam rubber part that wraps around the pushrod as well. These are disintegrating and will need replacing as well. Any help is appreciated.

I have never found this part all by it's self. I looked everywhere that I could think of. I was told if you purchase a booster rebuild kit you will find those parts in it. I found on at a junk yard. The booster was just lying there and the boot was good.
The foam piece is just a simple air filter. That you can make from any similar type product. It is there to keep dust from entering the back side of the booster and ruining the rubber diaphrams.
