I wish to pressure bleed and flush the brakes on my 1997 Cherokee Sport. I have been very impressed with the inexpensively priced DIY pressure-bleeding system available from Motive products and wish to use it for this task. However, there is one problem, the shop manual clearly states that in order to pressure bleed the front brakes the front brake metering valve must be held open by pushing or pulling on the valve stem. I have located the valve on the front (facing the grill) end of the machined aluminum combination valve. I plucked off the rubber grommet to examine the assembly. (the shop manual offers no diagram or detailed directions for this procedure) There is indeed a cylindrical stem, with a a hole in the center, that protrudes from and appears to be held fast by a large thin hex nut. My attempts to push or pull on the stem did not result in any movement, as far as I could ascertain the hex nut must be holding the stem in place. Could someone please provide me with a detailed description of exactly what it is I need to do in order to push in this metering valve. I¹m afraid if I loosen the hex nut the stem will blast out like a projectile showering me with valve parts and brake fluid. Any input would be greatly appreciated.
