I broke the big vacuum line to the hydrovac and haven’t been able to source a replacement. How bad would the brakes be without the boost of the hydrovac? I’ve seen dual chamber upgrades without any boost so I am wondering.
I haven't confirmed it myself, but a video I watched on hydrovac function (
www.youtube.com/watch?v=OnuZ1hWMA_M) suggests the hydrovac will allow fluid to pass though itself should the vacuum fail to move the piston. In theory you should be able to plug the vacuum line off until you can repair the lines and leave the hydrovac in the system.
Be aware that because you no longer have the hydrovac amplifying the pressure, the brakes will require more pedal force to stop. It shouldn't be road tested like this.
