A stud conversion allows the stud to remain in place while the caliper is removed using the mounting nuts. This helps reduce repeated wear at the upright threads and makes it easier to guide the caliper back into position.\u003c\/p\u003e\n\u003cp\u003eThe BCS-04 is useful during rotor replacement, brake inspections and other service requiring caliper removal.
