Parking Brake Control Identification - Vehicles with Hydraulic Brake Systems and Automatic Transmissions
The scope and purpose of the SAE Recommended Practice is to provide standards for the control and indication of parking brakes in hydraulic braked vehicles over 4540 kg (10000 lb) GVWR. This recommended practice pertains to automatic transmission applications and supplements the SAE J915 recommended practice. This recommended practice does not address parking brake system performance. Parking brake system performance, both static and dynamic conditions, is the responsibility of the OEM vehicle manufacturer or manufacturers that modify the vehicle by adding special vocational required equipment (such as but not limited to outriggers, cranes, etc.).
Rationale: After the initial publication of this recommended practice there has been additional information provided to the committee that warrants a revision to the document. The additional information will enhance the accuracy of this recommended practice and changes have been made to accommodate this input.
