Does the 99 have Vaccumm brakes? Or Hydroboost?

Well behind the Master Cylinder there would be a big round disk looking canister and if its Hydro there would be 3 hoses running to it, One to the ps pump one to the steering unit and one to the ps reservoir. If its Hydro then you dont need the Cummins Vac pump.
