Structural Testing of Passenger Car and Truck Disc Brakes(STABILIZED Nov 2014)
This SAE Recommended Practices specifies a procedure for determining structural strength and fatigue life of disc-brake caliper assemblies which are satisfactory for vehicle usage. It is applicable to new caliper assemblies which are employed in passenger car and truck brake systems utilizing hydraulic brake fluids. Brake design and vehicle performance requirements are not included. Specification limits are left to the discretion of the responsible manufacturer.
This procedure was developed for base brake operation and does not consider some unusual effects of ABS (Anti-Lock-Brake System) or Traction Control systems which may have a significant effect on the caliper. Careful analysis of the particular type ABS and/or Traction Control should be made and additional tests may be required which are not included in this document.
This Recommended Practice is being Stabilized because it represents caliper testing practices of the 1998 era and has not been materially revised since that time (just correction of typographical errors). The SAE Hydraulic Standards Committee does not plan to update this recommended practice, and instead has formed a Task Force that is currently working on SAE J2995 – Strength and Durability Testing for Automotive Hydraulic Brake Components to be based upon current technologies and to consider vehicle duty cycles. SAE J1713 should be stabilized since it may still be used as a reference.
