Hey new this forum . Just purchased a 05 Yukon xl Denali 6.0 AWD with active brake control. The vehicle locks brakes after around 5 min into driving . The car was from Nebraska not sure if that makes a difference and I’m in socal. Some say could be my brake lines and hoses and some say my wheel sensors any suggestions would gladly appreciate it thanks advance
I think stabiltrac would only cause the brakes to lock up if there was a abs sensor/module problem.
is there any ABS light?
any grinding noise while driving? or spinning a front wheel?
you can try pulling the abs fuse and drive it, this will cause a abs light to come on but will disable stabiltrack/traction control/abs. you can do this to confirm if the problem is the abs system or not. when you put the fuse back in the light will go out automatically.
if the brake lockup goes away with the fuse pulled then you need to have the abs system checked
if it doesn't then maybe pressure is building up in the master cylinder or something? not even sure if that is a thing, just guessing what would cause it to happen otherwise.
