I FOUND IT I FOUND IT I FOUND IT someone way back when blocked the vent line of the hydrovac with a wine cork.
i took it out cleaned it up and presstooo i have brakes.
all i have to do now is fine tune the brakes.
it was just a flewk that i found it but someone had said in a post i was reading that if you cant HEAR the sucking sound of the hydrovac its not working so i was gona take it off.
so i started to unhook the vent line that goes to the horse hair filter in the cab and found it wasnt even hooked up i looked in the end of the hose and there it was a cork from a wine bottle i took it out and did the start the truck with your foot on the brake test and my pedal moved {first time it did}
so i took it out cleaned it up hooked it up started the truck and i could hear the sucking sound of the hydrovac so i took it out for a test drive and MAN you hit the brakes and it will put 9 cents change on the dash
thanks for everyones help
sincerly perry
