im aware of the pressure/volume differences. a recap tho. i have put the mustang pbr dual piston calipers up front. the master cylinder is off of a jeep. i need to find out the size of the bores on the wrangler. i do not know what year it is fron. i need to find out what the bore sizes are on the mustangs also. see what the difference is. it dont feel like the front is getting enough pressure. probably to small a bore fore the front calipers and to large one for the rear? dave stohler ____________________________________________________________________________________ Looking for earth-friendly autos?
