took car out today when almost home lost brakes(hard pedal) found blown fuse, replaced worked for a few minutes and blew fuse again. What is the best conversion kit and where to get it? Thank you!
Go vacuum. Pretty much any auto parts store have the master and booster for a non turbo regaltook car out today when almost home lost brakes(hard pedal) found blown fuse, replaced worked for a few minutes and blew fuse again. What is the best conversion kit and where to get it? Thank you!

Assuming it's the motor replacing fuse only lasts a minute and brake presses in the driveway and it's only been in a year , want a more reliable systemits personal preference really…. I don't like the feel of Vacuum brakes… a good PowerMaster is hard to beat…. I like HydroBoost's feel better than Vacuum, but its install is more involved. Did you troubleshoot the Brake system yet? if the fuse keeps popping - the motor its probably staying on…. bad pressure switch or accumulator ball possibly. Do you have any extra parts that you could switch out?
if you do get rid of it let me know what you want for the broken core….. i need to mock up some things.

yeah the fuse is probably trying to save the motor from continuous running ….. i understand your pain. If you are just wanting to do the easiest switch possible, as said earlier, go vacuum. To me - i just don't like the pedal feel, I'm used to a firmer feel….. but as stated previously, just my personal preference.Assuming it's the motor replacing fuse only lasts a minute and brake presses in the driveway and it's only been in a year , want a more reliable system
You think it's the switch and not the motor? How do I verify?yeah the fuse is probably trying to save the motor from continuous running ….. i understand your pain.

Yeah was hoping for a simpler diognosisHave you read this sticky yet -----> http://www.turbobuick.com/forums/threads/powermaster-brakes-diagnostic-information.362564/
I have another bad one I replace last year but don't know what's wrong with it. How do I check switchIf you have access to spare parts [KNOWN GOOD] you can switch either the switch or accumulator ball out quickly and test operation…. those are the two parts that frequently fail.

OK switch is gray don't know what new to old accumulator looks like the motor pumps fluid out of inside master like it should but motor runs every time brake pedal is pressed but it does cycle runs for a bit and shuts off until u release pedal and apply brake again runs every time. There is no fluid leakage anywherei think the main failure on switches was fluid leaking when the went bad…. Does your system have the Gray pressure switch? Is the accumulator ball the newer style? when you replace the fuse, does the pump just continuously stay on?
aaron
If the fuse bows the motor is shot.
The best replacement is hydroboost. Vacuum is second and a lot less money.
I am removing a brand new vacuum system with the bigger booster and new master. Shoot me a message if you are interested.

The simplest test would be to swap out accumulator balls - BE VERY VERY CAREFUL - you must discharge system pressure first, with key off keep stepping on brake pedal until it's hard , then u can replace itOK switch is gray don't know what new to old accumulator looks like the motor pumps fluid out of inside master like it should but motor runs every time brake pedal is pressed.
