I don't know where else to ask because i am at wits end with this truck and hope its OK to ask here. I've been fixing the brakes on my dads 2001 dodge ram. It was a complete mess, the hose on the passenger side rear caliper broke and there are no replacements available except spending $350 at the dealership for a hose(crazy I know) so he just crimped off the hard line and drove it on 1 rear brake for a while. In the last week brake fluid started pouring out of the drivers side rear brake and i put it up on jackstands and started to fix the whole mess. I got new discs, calipers, and used a hose off a different truck that was almost identical. ive bled brakes atleast 20 times in the past, and for some reason I just cant get a firm pedal pressure on this truck! Normally its rock solid. I started at the wheel furthest from the m/c and worked my way to the wheel closer to it. For some reason I just can't get the air out of the rear brakes now matter how many times we try. I tried loosening up the fitting right by the m/c to try and bleed it even, but that didnt change anything. Where can i start looking to finally fix this thing?
