Thanks ALL! 48bigtrucks, howdy 'n welcome . I'm pretty new here too. We bled my brakes and they're working fine now. I don't trust them tho and will follow advice from this thread and my other one"Brake cylinder failed,part2"(or something like that).Tomorrow I'm gonna tighten every connection on the whole system. I'm looking into a dual master too. Your experience is interesting 'n I'll check it out. Thanks ALL,again. jim
