abs light is on
i am having an issue of the front brakes applying themselves for no reason.. when this happens the brake pedal is all the way out and has no pedal travel [pedal is very firm] also the abs light is on
I recently changed out the rotors and pads on the front brakes ,at that time the right front caliper was also replaced because of sticking. when i discovered that the brakes were sticking i was too far from home to stop so I had to drive another few miles before reaching home. This caused the right side rotor to glow orange[ the sticking caliper] so, the caliper was changed and thorougaly bled out using a vacum pump and someone pumping the brakes,
Could the excessive heat cause the sensor in the hub assembly to malfunction and could this also be a faulty hub bearing issue?
The drivers side hub bearing was replaced a couple years back, any one with a similar issue on their truck?
Both front brakes were sticking, not just the right side ...

do you mean the front calipers are dragging or the abs pump is activating and you hear the pump valves buzzing?
dragging brakes with hot rotors, no brake pedal free play is a symptom of a bad master cylinder. I would check the calipers and flex lines also. If its more than one wheel stuck on...master is the more likely issue.
post your code and see if its helps with diagnosis. Sometimes abs modules will set irrationality dtc when it sees brake pressure in the system but the pedal is not pressed.
