Did you replace the Parking brake seals? You did'nt say what the dealer told you to repair! The best thing to do is check the tranmission oil level, to see if it is rising! it could be the park brake seals leaking into the transmission!

best way to check this would be a porta power pump with a pressure gauge, remove the hose going in to the park brake (with the machine switched off) conect the porta power hose and pump to the pressure the brake works at (2500 psi i think) if the pressure drops the seal are most likely leaking!

hope this helps

sorry about that ... they said park brake sensors were bad replaced both upper and lower solinoids and 2 hoses they said had pin holes in ....tech showed up at 6:45 this morning after a brief while he was able to pin point problem with the park brake Actuator Switch and was able to free it up so we could move loader out of the way ....ill get some pics soon
