When your Powermaster brake system fails, and there’s no doubt it will, you have a decision to make. So you will have to choose one:
A) Replace with another Powermaster, that will eventually fail again.
B) Replace with a vacuum brake system.
(we told you how here)
C) Replace with a Hydroboost brake system.
This last option is what this Buick Grand National owner did.
Watch the video below to see the complete process, from removing the old Powermaster to installing the new Hydroboost system.
[ note that a lot of companies make these brake kits, not just the one mentioned in the video, as they are all pretty similar ]
