Not sure if im posting in the right spot but this one seemed to make sense. My truck has been sitting for about a year due to repairs and lack of money. Anyway im trying to get it ready to get back on the road and all but the brakes seem to be stiff. If i had to stop quick it would never make it. I replaced the line that goes from the brake booster to the intake manifold. I was wondering if anyone could help me out with suggestions to check and were to go to fix this. Another thought i had was the small gray cirlce that the line connects to, could that be bad? thanks guys
