A couple of the auto parts chains have the entire unit for less than $200 with a lifetime warrenty. Advanced auto parts is one of them. The only other option is going to a vacuume system which a lot of people have done. The vacuume conversion is only about $150 and I think John Dicarlo has them for sale in the FOR SALE section for around $125.

convert to vacuum brakes.

If you don't, I have a new accumulator you can have for cheap.

There is a guy on line that sells NEW motors:

I just converted to vacuum about 3 weeks ago. Its the way to go IMO. The Powermonster accumulator ball I was getting from GM kept going out every year. Remember, most of these parts have not been made in a while, so they are sitting around in warehouses losing their charges, etc.

Does a bad accumulator ball cause a haed paedal?

Hard pedal is what I meant...

could be.

If the accumulator goes bad, replace it ASAP, or you will blow out your motor.

There is a troubleshooting checklist at gnttype.org:
