Section 13:20-50A.3 - Brakes

(a) A brake system, including service brakes and parking brake, shall be provided.

(b) School buses using air in the operation of the brake system shall be equipped with a warning signal, readily audible or visible to the driver, that will emit a continuous warning when the air pressure available in the brake system is 55 pounds per square inch and below. The warning signal shall be capable of alerting the driver while the school bus is being operated. An illuminated gauge that will indicate to the driver the air pressure in the brake system in pounds per square inch shall be provided.

1. The brake system dry reservoir shall be safeguarded by a check valve or equivalent device so that in the event of failure or leakage in its connection to the source of compressed air, the stored dry air shall not be depleted by the failure or leakage.

(c) Except as otherwise provided for Type B school buses constructed on a cutaway chassis, Type B, C, and D school buses using a hydraulic-assist brake system shall be equipped with a back-up pump system and warning signal, readily audible or visible to the driver, that will emit a continuous warning in the event of a loss of fluid flow from the primary source or a failure of the back-up pump system. Type A school buses and Type B school buses constructed on a cutaway chassis using a hydraulic-assist brake system may be equipped in accordance with FMVSS No. 105 (49 CFR 571.105), incorporated herein by reference.

(d) The brake lines, booster-assist lines, and control cables shall be protected from excessive heat, vibration, and corrosion and shall be installed in a manner so as to prevent chafing.

(e) The brake system shall be designed to permit the visual inspection of brake lining wear without the removal of any chassis components.

(f) The parking brake shall hold the school bus stationary, or to a limit of traction of the braked wheels, on a 20 percent grade under any condition of legal loading on a surface free of snow, ice, or loose material.

(g) When applied, the parking brake shall remain in the applied position with the capacity set forth in (f) above despite the exhaustion of the source of the energy used for the application of the parking brake or leakage of any kind.

(h) On Type A, B, C, and D school buses, the parking brake control shall be mounted in accordance with the chassis manufacturer's specifications to the right or left of the driver in a position that is easily accessible to the driver.

(i) The parking brake shall be equipped with a warning device visible to the driver that will indicate that the parking brake is engaged.
