Brake Fluid issue...
« on: May 20, 2012, 07:24:12 PM »
Okay so I replaced the right rear caliper on my 05 LJ and then new pads on both ends of the diff. Blead the brake line on the side I replaced, topped up the fluid.  Now I see the front calipers dragging a bit, not fully releasing. If I missed some air bubbles in the system can that cuase the problem I am seeing in the front...??    I just took both fronts apart to inspect and the pistons both moved as they should when I used the "C" clamp to push them back. But before I took them off the rotors they were clamping a bit...  Does this sound like a problem of air bubbles in the brake system..???   Help

i am thinking that is unrelated to the back brakes.  You shouldn't have gotten air that far up the system to get pushed into the fronts.  Even if there was a bit of air in the fronts i don't presume it would make for dragging brakes. 

I would take off your front calipers and clean/lube the sliders.  most dragging issues come from that.  i cooked a rotor and pad recently because of mud drying out between the caliper and support.  couldn't slide, and just went down hill as things warmed up.

This ^^, air in the brakes makes your peddle squishy and unresponsive as the air compresses under pressure. If the caliper isn't pushed back in slowly and carefully (not to include dirt or debris or damage anything) it can drag. You probably will need new calipers from the sounds of things if cleaning does not work....But I'm no expert

Thanks for the thoughts...  I'll pick up some of that brake lube stuff and slick up the sliders.  Already cleanned them tonight.  Pedal feels strong, not mushy at all.   Will let ya know...
