I have developed an experimental brake bleeder kit for any MT700 series Challenger tractor. This kit will eliminate the "delay" in wheel brake application and the hard "hit" when the brakes finally do come on. I have four kits out and need more testing (all four have said I can't have my parts back...the kit really works good!!). E-mail or call my cell 217-622-5862 after 6 pm central time. $45 plus shipping. Thank you. Rick.
