ive contemplated replacing it but rarely drive it, in fact i've put less then 9K on it since ive owned it. i blew the fuse awhile back replaced it and the pedal has been hard as a brick with the exception of a few times. Now i've read that the fluid needs to be replaced and how horrible the power master unit is. Before i replace the power master unit i wanted some opinions. I have a guy not to far from me who had one he pulled from a junker but never got back to him about it.not sure if he sold it or not but i've been wanting to put some miles on it and before i do i wanted to replace it. also what is the difficulty in replacing it?
