Had exactly the same problem with brand new one years back on my sunliner, seemed to make little difference despite new brake components throughout, only thought was maybe low vacuum, i even added reserve vac tank but didnt help so removed it, disapointed.

I have installed this PB system on my car . I really cannot tell much difference in the amount of pressure I need to stop the car. Seems like I have to push just as hard as I did without the PB set up. The unit I have was rebuilt in 1996 and had not been installed on a car. Anyone have any experience with this unit? Thanks G.S.
