Breaks keep locking up - 1998 Dodge Durango

Any one of the the pulleys down in front can do it. All the pulleys should turn freely. Except the lowest, center on. It is the crankshaft.

Usually the belt is too loose, or one of the pulleys is not aligned, or one of the pulleys is locking up.

check the rubber hose they sometimes break inside causing it not to let fluid to to retract therefore it keeps pressure on the caliper

normaly yes as u end up haveing a air lock break pedal will keep hitting floor hope this helps cheers gaz

the problem is probably the ignition lock cylinder. the ignition lock cylinder has two wires coming off it, after tine they will break. to repair need to replace the lock cylinder code the new lock cylinder and replace the key

After cover has been remove you'll see the bolts that hold the lock, when lock was install the head of the bolts are made to break off for theft reasons, get a small chisel and hit the bolt as to loosen it, once it breaks loose they'll come off easy, when installing new lock keep turning bolt till the head of the small bolt breaks off, it made to do that.

If rear, then parking brake possible cause.
But front and rear calipers often lock from corrosion on piston or binding on sliding parts.
Remove caliper, remove piston with compressed air or greasegun, clean corrosion, clean all grease out, replace seals. (compressed air is dangerous!)

I would chg. the break hose, the one from the caliper to the hard line. Break fluid runs to caliper and back thru same hose, fluid is not running back hense caliper stays compressed or locked.

front brake calipers are probably sticking.

you probably need to bleed the entire system.starting from the farthest wheel to the nearest.
