first off.. i dont want to do a vac brake conversion. when i hit the brake the brake light goes on and i have a hard pedal little to no brakes then once the light goes out it'll fall and have brakes fine. to my understanding this is the accumulator ball. so.. do i just swap the ball or the whole pm?
-
Sounds like the ball to me, I just bit the bullet and went to vacuum. Couldn't find an accumulator for less than $250, and if you do find one, Lord knows how old the damn thing is.
-
i know brian has them for $189. i just dont want the problems that go along with the vac. brakes i dont have patents to deal with vac leaks.
-
Kirban has the ball for around $179. That's the cheapest if buyng from a store.

What problems??? I never had an issue with vac brakes ...now PM brakes ..good god!!! I could write a novel on the problems I have had with that system.
-
Both systems have there ups and downs. If all you need is a ball then just do that. If your PM is still original, its a good chance the motor and pressure switch can be going out too. To replace the complete PM or VB conversion the correct way can be close in $$$ spent. Either will work fine when done.
-
ed what do you recomend? i can get the whole conversion kit for 380? from brian.
-
I got mine from Red Regal T o TBS for about 200 bones. I still have one of the last PM's made, as I had the entire system replaced a few years back. If my buddy doesn't want it, it's yours. The ball is blown to shit, but it has the right switch and a the entire master is new. Let me ask him.

You can buy any junk G-body and get the entire "conversion kit"
really cheap. I kept the entire setup from my '86 Grand Prix just in case.
Remember that you also need the pedal assembly too.
However, I'd try fixing the powermonster first ...

+1 on the vacuum conversion.

And it does sou nd like the accumulator. Deos the motor run a lot?

Avoid vacuum at all costs, despite what the chum-smugglers above said. Unless you never want build boost on the line again...
Was there ever any news about a new aftermarket company making PMs again? I thought I'd heard whisperings. Up until a few years ago you could get an entire new PM from AutoZone with a lifetime warranty for around $350...I wish that deal would come back- as soon as it does I'm putting a .270 round through the vac setup before I switch back.

nope. only when you hit the brake and again when the pedal falls to normal

WTF ??????

I'm still wondering if we can use an accumulator off a foreign car, I forget you has them, I want to say Saab or something. Shouldn't be more than an adapter or something right?
