prostar no clutch pedal

You probably have to bleed the slave also. The problem I had with that unit is the the plastic drain where the reservoir is mounted was broken, not allowing fluid from reservoir to reach master. I really don't care much for that hyd clutch, had to push the pedal to the floor to get it in gear, by the end of the day my knee was killing me, wound up telling the owner, no more. As far as the rest of the truck, it pulled Ok, maxed out at 74mph, and between the cab airride and air susp, rode pretty good.

 

International does not recommend replacing master and not slave (that may just be to sell parts, but we always replace as a pair)
