ZJ front brake change no pressure

I know this is probably a repeat but i am new here. My ZJ is a daily driver not a trail rig so I need it back up as quickly as possible. I have bled and re bled brakes several times my bleeders are frozen and rounded off so have been bleeding from main connection on calipers is this a problem? i can get brakes to pump up with engine off but no pressure at all when running any and all help is greatly appreciated.

Welcome to the forum! The frozen bleeders are not a good thing. Cracking the line may be letting air in as well as fluid out. You shouldn't have to pump the brakes to build pressure so you still have air in there probably. At this point its kind of go for broke thing on the bleeders. Vice grips, hammering on a smaller wrench or socket, might work. But if they are really stuck bad they will probably snap off. If you had the time you could try some rust penetrant soaking a few days. Rebuilt calipers aren't that expensive.

Yeah, you need to be able to open the bleeders to bleed them properly.

I hope the vise-grips do it for you. If not, I wonder if one could use one of the cam-style stud-removers on it? The one I have is a 1/2" drive, so you can really get some torque on it, and I think they bite pretty well. There is a question of room to work though. Just a thought. Good luck.

If you're not in the middle of nowhere I'd just replace the calipers, they should be all of $20 a pop.

Thats what I did when one of my bleeders sheared.

Got it done vise grips did the trick Brakes are working now but i still have the Skronk skronk skronk noise that led me to do the brake job in the first place. checked bearings while i had things torn down they seem to be tight and no noise issues also cut off a broken piece of dust shield that i thought might be the culprit but noise is still there. Seems to be coming from left front wheel. any Ideas would be helpful.

Did you do a complete brake-job on the front, i.e, new pads, new or turned rotors? My fronts make some noises now and then, mostly after a rain or cool, moist weather period, but it subsides after a few good brakings. I figured it has something to do with my ceramic pads. Admittedly, I did not turn or replace the rotors on my last brake job, so that might be a culprit. Good luck.

Yeah, I was thinking that a 3/8", or even 1/4" drive tool would have a better chance in smaller areas. The 1/2" drive is pretty large. So yes, a set would be nice. I haven't seen them. But I haven't been looking either. Maybe there's a Binford 5000, gas-powered model available for you, Tim...er...coralman.
