Welcome to Justanswer ! my name is XXXXX XXXXX i will do my best to assist you with this problem
will just the front brakes lock up and smoke ?
is this 4WAL or RWAL set up in this?
its just front brakes and this is a 2wd rear wheel 1/2 ton
before driving I can jack up and spin wheel but if I press brake and let off it will not spin if it sits awile it will spin again if I drive after all that and jack up it will not spin....now I can use a one man bleeder and use it to release pressure on caliper by attaching clear hose to bleeder screw and let off pressure do you think I need to replace master cylinder
yes I think the master cylinder is bad
get the front wheels to lock up THEN loosen the lines off the master cylinder if they unstick its the master cylinder causing this problem
since you can release the pressure by opening the bleeders and the front rubber lines are new more than liked the master cylinder is causing this
