After the last race, I was taking my nephews around the block for some joy rides and I all but lost the brakes... I can still stop the truck, but its a FAR and hard pedal. Could be the MC, its still got fluid in it so I don't suspect a bad line or leak, but I thought I replaced the MC a couple years ago when I put the truck together.... but I might not have I was also suspecting maybe I lost the booster, cause I know when you do it becomes VERY hard to hit the woh pedal when you loose the boost. So that got me wondering how you test the booster? Just pull a vacuum on it with a gauge and see if it leaks down? Or is there another (better) way? Hmm, as I was typing here I wonder if maybe its the rear brakes.... They never really worked, I've never messed with them... but I would think the front brakes still would work just fine. Thoughts, suggestions, anyone want to volunteer to come over and wash the truck so I can work on it Opps, almost made the newbie mistake... Scout II, 304, 727 auto, I think the chassis was a '74 IIRC, the brake assembly was off my shelf.
