| Resumen del asunto | ¿Debería incluirse la falta de un pasador de chaveta en el criterio del 20 % de OOS para los frenos? (horquilla y ajustador de holgura). |
| Justificación o necesidad | Sin el pasador de chaveta, el pasador de horquilla se afloja entre la horquilla y el ajustador de holgura. Una vez que el pasador de horquilla se sale, el freno puede quedar inoperativo. |
| Solicitud de acción | Analice la gravedad del pasador de chaveta en el pasador de horquilla y, si se considera necesario, agréguelo a los elementos externos que se enumeran en los criterios del 20 % para los frenos para dejar claro que forman parte de los criterios si se consideran un peligro inminente. |
| Medidas adoptadas por el comité | Discussion in committee with the brake manufacturers indicated that the majority of them (all but one) felt that the timeframe that it takes for the clevis pin to fall out when there is no retainer present when the brake are being used is not that long and that this condition should be included as an OOS condition in the 20%. Further discussion indicated that in some cases, other things besides a cotter pin can be used and it should not be considered a defect if it is not a cotter pin and therefore the wording “cotter pin” was not used to reflect the only thing that could be used, it was only included as an example. The committee unanimously voted to include this condition in the 20% criterion as follows: Including this condition in section 1.a.(5) and 1.a.(6) addresses the condition as a defect to be included in the 20% criterion. 1.a. (5) Drum (Cam-Type and Wedge) Air Brakes (a) Missing or broken brake shoe, lining, return spring (shoe or chamber), anchor pin, spider, cam roller, camshaft, pushrod, yoke, clevis pin, clevis pin retainer (e.g. cotter pin), brake adjuster, parking brake power spring, or air chamber mounting bolt. (393.48(a)) 1.a. (6)Air Disc Brakes (Exposed Pushrods and Direct Coupled – Air Chamber to Caliper) (a) Missing or broken caliper, brake pad, pad retaining component, pushrod, yoke, clevis pin, clevis pin retainer (e.g. cotter pin), brake adjuster, parking brake power spring, chamber return spring, or air chamber mounting bolt. The motion was passed by the Executive Committee. |
