I tried pressure bleeding the brakes yesterday. The backs bleed no problems but when I tried the front passenger I got nothing coming out of the bleeder or the caliper with the bleeder removed, I didn't bother trying the other side. I have a new 24 mm Chrysler manual MC, new flex lines and new reman B52 conventional calipers. The brakes lines are cunifer installed about 5 years ago. With the pump method the front calipers bled so with the 10 lbs pressure I can't think of why the calipers will not bleed.....any ideas?.....
