Absolutely entitled to you "opinion"...the over-riding factor thought,is that they...have failed and will fail without warning...serviced regularly...new pressure ball..new pressure switch..new fluid..it wont matter....and as we get to an investment point with these cars reaching into tens of thousands....why would anyone want to risk it? imho.I know alot of people chnge out their brake systems to either of those two but personally i believe that a well maintained original powerbooster is still the best system for our cars,of course just my opinion.
So you stop spinning your wheels,replace the lines with steel braided and run synthetic fluid and put disk brakes in the back.your gn will never stop better.I ordered my 86 new and it's brakes have always been push and pray. There is no such thing as locking up the brakes. I have had the whole system replaced by GM, had the master cylinder replaced again by GM, too many accumulators and pressure switches to count. I also made the mistake of buying one of the "New Powermaster Motor/Pump" replacements from Hank Terry with the wonderful warranty that it will be replaced for "FREE" if you have receipts for a new accumulator and pressure switch and the motor burned up to a crisp in two days and big surprise..........no such thing as a warranty. I finally gave up and put the old (presumed dying ) motor back on and worked with non-GM vendors set up a new larger rechargeable accumulator and a heavy duty pressure switch. That set up lasted me almost 10 years with no problems, but still limited braking. Time to swap over to something that actuallyb will stop when I need it to. How GM ever let a car out the door that you could put the pedal to the floor and barely stop is beyond me. Any other car or truck I've owned (pre-ABS) would be skidding down to a stop if I did that.

Easy with the powermaster drama.i drive the hell out mine a lot faster than most will ever go and I still run a powermaster.its not a crap system just needs to be maintained and if you want corvette braking your still going to need the things I've mentioned.i did things in stages and know what helped a little and a lot and I can tell you the lines/syn fluid are a big deal,the expansion of the fluid in the rubber lines as it heats up kills the brakes.ive seen a lot of these cars but in the end it's your call as its your car put in what you feel you like.But then I've got more money into a crap system that never worked right since new and still not enough braking power to stop safely.
For the same money I can put in a Hydroboost system and have brakes that actually work and never lose another dime to the powermonster. No matter what anyone does the powermaster will fail again and again. The accumulators were designed to be a long term money maker for GM, always failing and sealed instead of rechargeable so you have to buy a new one from them (GM Part only). An industrial pressure switch could have lasted the life of these cars, but that wouldn't have insured GM a steady income from parts either.
Between all the parts I've bought for it, crossing my fingers every time I drive it that a brake light won't come on (or just lose the brakes and then have the light come on) and finally having to redesign the system myself to finally get it to run problem free (alas still with no real braking power) I am totally done with this joke of a brake system.

With that list, the only thing left is the lines! No good reason the car shouldn't stop well if all those components have been replaces.
That's why you didn't see the improvements because they weren't the problem in the first place.Every part of this braking system has been replaced at least twice since new. Most of the parts have been replaced too many times to count and it has never made any difference in the way the car stops. The biggest change in braking power was when (as previously stated) I worked with a few companies and came up with a larger rechargeable accumulator and heavy duty pressure switch to work with the powermaster. But even that would never lock up the brakes, it just slowed the car down a bit faster. and stopped the endless swapping out of accumulators, motors, and pressure switches.
Then what is the problem?That's why you didn't see the improvements because they weren't the problem in the first place.
I made suggestions in my postsThen what is the problem?
