A hub rotor assembly includes a hub, a rotor supported by the hub and a plurality of fasteners that connect the rotor to the hub. The hub includes a wheel mounting flange and rotor mounting flange to which a flange of the rotor is attached. The rotor mounting flange has a larger diameter than the wheel mounting flange, or other hub elements outboard of the rotor mounting flange, so that the rotor can be easily removed from the hub. Features of the invention also include floatation elements associated with a fastener to fasten the rotor to the hub while allowing the rotor to move or float relative to the hub. A spring clip may be used with the floatation elements to prevent the rotor from rattling. The assembly is particularly suited for commercial highway vehicles and high performance vehicles.

A method according to claim 1 wherein said step (v) comprises: generating said maintenance flag indication in response to said step (c) resulting in an upward adjustment of said average defect rate in a plurality of said periods. 10. A method according to claim 1 wherein said step (c) comprises: periodically generating a new value of said average defect rate indication as (i) the existing average defect rate indication plus (ii) one-half of the difference between (1) a newly calculated arithmetical mean of said defect rate over a plurality of said periods and (2) the existing average defect rate indication. 11. A method according to claim 1 further comprising: generating a lower threshold indication in response to said average defect rate indication and said deviation indication. 12. A method according to claim 11 wherein said step (c) comprises: generating a new value of said average defect rate indication in any one of said periods in response to said corresponding number of said defect indications being less than said corresponding lower threshold indication in a plurality of said periods. 13. A method according to claim 11 wherein: said average defect rate is adjusted downwardly. 14. A method according to claim 8 wherein said step (c) further comprises: generating a new value of said average defect rate indication in any one of said periods in response to said number of said defect indications exceeding said corresponding upper threshold indication in a plurality of said periods. 15. A method according to claim 1 wherein said step (v) comprises: selectively generating said maintenance flag indication following a particular event. 16. A method according to claim 15 wherein: said maintenance flag is generated only following a particular event. 17. A method according to claim 15 wherein said particular event is at least one of one of (i) a visit to said elevator by maintenance personnel or (ii) a request that information about the condition of the elevator be provided. 18. A method according to claim 1 wherein: said step (c) results in adjusting said average defect rate upwardly only if the total number of said operations, occurring since said maintenance flag was generated concurrently with said visit, is less than a related threshold number of operations. 19. A method according to claim 1 wherein: said step (c) results in adjusting said average defect rate upwardly only if the total lapse of time, since said maintenance flag was generated concurrently with said visit, is less than a related threshold amount of time. 20. A method according to claim 1 wherein said step (v) comprises: selectively generating said maintenance flag indication following a particular event in response to the number of said defect indications recorded in at least one of said periods exceeding said corresponding upper threshold indication, and said step (c) does not thereafter and prior to said particular event result in a downward adjustment of said average defect rate. 21. A method according to claim 1 wherein said step (v) comprises: selectively generating said maintenance flag indication following a particular event in response to said step (c) resulting in an upward adjustment of said average defect rate and said step (c) does not thereafter and prior to said particular event result in a downward adjustment of said average defect rate. 22. A method according to claim 1 wherein: said step (v) comprises: selectively generating said maintenance flag indication following a particular event in response to the number of said defect indications recorded in one of said periods exceeding said correspon ding upper threshold only if the total number of said operations, since the number of said defect indications recorded in one of said periods exceeded said corresponding threshold, is less than a related threshold number of operations. 23. A method according to claim 1 wherein: said step (v) comprises: selectively generating said maintenance flag indication following a particular event in response to said step (c) resulting in an upward adjustment of said average defect rate only if the total number of said operations, since said step (c) resulted in an upward adjustment of said average defect rate, is less than a related threshold number of operations. 8744, 19851200, Gibb, 166/335; US-4565252, 19860100, Campbell et al., 175/269; US-4573541, 19860300, Josse et al., 175/078; US-4599172, 19860700, Gardes, 210/314; US-4600061, 19860700, Richards, 175/062; US-4605076, 19860800, Goodhart, 175/061; US-4611855, 19860900, Richards, 299/002; US-4618009, 19861000, Carter et al., 175/267; US-4638949, 19870100, Mancel, 239/307; US-4646836, 19870300, Goodhart, 166/303; US-4674579, 19870600, Geller et al., 175/045; US-4702314, 19871000, Huang et al., 166/245; US-4705431, 19871100, Gadelle et al., 405/267; US-4715440, 19871200, Boxell et al., 166/100; US-4753485, 19880600, Goodhart, 299/005; US-4754819, 19880700, Dellinger, 175/061; US-4756367, 19880700, Puri et al., 166/263; US-4763734, 1
