today i was working on a tubocharged-supercharged-6v Detroit diesel (4 stroke) engine and came up with this question....

ok if you have a vacuum brake booster it gets it vacuum from the intake manifold (or somewhere near there). but what if you have a turbo turning that vacuum into pressure? would that make your brakes harder to press? how does that work? or is my logic just so far out there you guys dont get what i am saying? thanks for any responces!

Well assumably when applying the brakes your foot is off the gas normal vacuum is restored when the throttle blades close.

vacuum canister and a check valve. except on a diesel. it works off a vacuum pump on them if they don't have hydroboost.

 

The TTA's and GN/T-types use an electric pump to provide fluid under pressure for power assist purposes when the vacuum turns to boost. They also have an accumulator that stores high pressure fluid for their 'power brakes'. I think it gives you about fifteen normal applications of the brakes worth of stored fluid in the accumulator.

Most diesel engines use a form of engine driven pump to pressurize a fluid (power steering usually) that is used to provide power assist for their brake systems. They also use an accumulator to store pressurized fluid.

Some other diesel engines use a vacuum pump like others have mentioned that provides vacuum to operate any accessories as well as the power assist brake system.
