1800 Brake Booster 1800



About 15 years ago I sold my beloved 72 1800F to a good friend. He's done very little with it and drives it only occasionally. But he'd never part with it.A year ago I bought a 70 1800E that had sat for a while and extensively rebuilt the brakes. Rotors are like new, but I disassembled the rear calipers and cleaned out all the gunk, replaced the front and rear pads with Repco, added IPD braided stainless steel lines fore and aft and bled the system thoroughly.

Brakes work well, but when I recently drove my friend's '72, I noticed his brakes worked much better. This, too, has Repco pads, the rotors are not as good as mine and it has the original rubber lines. I know from flushing his system for him that the rear rubber lines are swelled and restricted and should be replaced. Still, his brakes are noticeably better than mine. I'd like to know why. I suspect the brake booster.

Vacuum line is OK, as is the in-line check valve. If I disconnect the booster, Whoa, Nelly!. So it is working. I'm just wondering if this thing is go/no go or if it can work partially. The Haynes Manual is absolutely no help with these "newer" boosters, referring to an air filter but not showing you how to access it. Just wondering if anyone can shed any light on the situation.

Thanks,

Dave B
