i left for work this morning and everything was fine. About a mile before i get there i slowed down for a curve and after that my front driver brake wouldnt release. i limped it thinking ill work on it after work. I jumped in the truck at the end of the day and they had released so i went to go tow my buddies duramax which had quit on him.

As i was pulling him both front brakes locked up and wouldnt release. I opend the master cylinder cap there was no air, there was a little pressure in the powersteering but i opened the cap and they still didnt realese. finally i undid the bleeder screw which got them released, i had to stop ever 5 miles to undo the bleeder screw again because they kept locking up.

after i pulled him i drove home and never had a problem again. now i cant get them to lock up again could it be my mastrer cylinder or hydrobooster maybe? Im not sure what to replace i might try flushing the master cylinder tomorrow after work.

I dont wana drive it cause i cant get stuck anywere with it:mad2:
 
there's been a few cases when a brake line has failed internally and caused that, but that would only affect one brake
