Thanks for all your help, the links provided were a great visual aid. I did find that the brake lamp switch was misadjusted. I corrected the fault. I was able to get the cruise control to work again. Thanks again
It is possible to gain access to the parking brake adjuster with the rotor still installed. Use a long flat head screw driver thru the lug holes while Using a flash light and rotating the rotor locate the star adjuster and rotate it. This might free up the binding rotor.
