Howdy all. My 49's brake system is a lil' suspect right now. When I first got her runnin' she had a tendency to lock the rear wheels. Hydr-vac was definitely working as there was a definite difference in eng running versus eng off. brakes were pretty touchy for awhile initially. I tried to adjust brakes in front and rear to balance them. But on start up rear brakes would initially lock. and then they would be a little smoother with running time. Now I get an initial lock and then my brakes take a lot more pressure to initialize then before. Like the vac isn't working. Much harder brake force is needed to stop her. My question is, do these trucks take a pretty stiff leg pressure to stop even when the vac is working propewrly. Or should I be able to just hit the peddle lightly to stop? Also, the air intake located at the hydro-vac is naked. No filter or connecting hose. Does this tube need to be routed to the air filter to the engine? Or just a simple filter at the source? I'm borderline tearing it apart and rebuilding it. But don't fix it if it aint broke? Appreciate all help. And sorry for the long thread.
