My ABS light just came on and the front left brake is pulling hard on the truck. I was wondering if I unhook the sensor will it keep it from seizing up any worse until I am able to fix it on Friday? Would it work as a bypass even if the light stays on or how would it work?

 

Sounds like you need to flush the caliper first then see what happens. The ABS sensor has nothing to do with moving the caliper.
