benzmac, my tech flush the brake, check the abs pump, still front brake is stuck. he then
disconnected the abs computer to run w/out abs. still the front brake still
stuck. tried to move the piston on front caliper. it move freely but when you put back
the tires and drive it the front brake again
would stick. we suspect the master cylinder.
he check the abs pump it works.
any suggestions?

thanks
