97 nissan hardbody. 4 cyl. 4 wheel drive. 5 speed. Buddy of mine got it few weeks ago. Brakes worked. A line blew. So he got over 800$ in all new front end parts and new brake lines from front to rear. Had someone do all the work except the brake lines. Him and i put those in last night and today. Bled the entire system out have straight fluid at all 4 wheels. The rear shoes are adjusted right. No vacuum leaks. Truck has been parked and not driven. Wouldnt think it would be the booster. Have bled the lsv or abs module or whatever the things called under the pass side inside the frame rail. Were at a loss here. Need done asap. No leaks. All new lines right to the rubber lines as well. Much help as i can get would be very much appreciated.
