Need help air is getting in my brakes! (Updated)
This is the deal with my brakes. 4 months ago I started driving after a complete frame off. Here is everything i replaced in the braking system: New calipers, pads, discs, stainless flex hoses, all new hard lines (preflared autoparts store lines, bent to fit my me), adjustable proportioning valve, drums, shoes, drum hardware, and wheel cylinders. The MC and power booster were new to me but not new. I got, or seemed to get, all the air out of the system 4 months ago, and had a very firm brake pedal for a while.
Now i have air in system. I have to pump before every stop or i get nothin, which probably means i have a lot of air in the brakes. I have tried to bleed them twice already. Both times i got a little air out, but not much. I have tried pumping and gravity bleeding.
Two questions: One, where is this air coming from? I have examined every inch of the lines and i can not find any fluid leaking out. Two, why can't i get all the air out? What is a good length of time to gravity bleed the brakes for? Thanks for your time, it is appreciated as always ~ Tim
