I'm sorry - this is not about anything stock. I need to some help diagnosing brake issue.
A local guy help me redoing the brakes on my 40 after a dana 60/14 bolt axle swap. He replaced all the brake lines with new hard lines and a new chevy master cylinder with adapter. And, it worked great when we took delivery.
But, after sitting for about 4 weeks, I took it out for a drive and the brakes were awful. Not just loss of power boost awful, but unable to bring the 40 to a stop even on a slight hill.
When I got home, I tested the booster key on (pedal should drop) and key off (pedal should not come up). It failed the key off test, but then I realized there's no check valve, so that makes sense. So, it doesn't appear to be the booster. So, I can't figure out what it might be. It's not like some of the brakes are bad, they are equally bad. So, it's not one of the circuits or some of the calipers, otherwise you'd feel it braking unevenly. It's still braking evenly. that made me think that maybe there's something obstructing the pedal from going all the way down, but I couldn't find anything.
What else can I look at?
