Many years ago when cars all ran around with drum brakes, power brakes were not a necessity as drum brakes naturally provide some of their own power assist. Today, most modern cars have 4 wheel disc brakes and without power brakes it would be quite the workout just to haul your vehicle to a stop.
The power brake booster uses vacuum produced by the motor to multiply the force you foot is applying to the master cylinder. Well you ask, “what happens if your mot0r isn’t making enough vacuum to properly power the system?” Hold on one second….BAD BRAKES!!!
Pictured is a mildly modified LS5 Chevelle that we upgraded with a nice brake set up from Baer and a killer suspension set up from DSE. What’s the problem??? The car has an aftermarket cam set up and the motor doesn’t make enough intake vacuum for the power brakes to perform properly. The equation is simple: fast car+poorly operating brakes = SCARY!
The solution is easy: install a Hydroboost brake system that relies on hydraulic pressure to make it work and forget about the vacuum nightmare. All we need to do is reroute the output from the power steering pump and let the new booster and the PS fluid do all the dirty work.
