An Experimental Investigation of Brake Rotor DTV Under Laboratory Conditions - Part 3

This study continues work from SAE Technical Papers 2008-01-2543 and 2009-01-3044 that demonstrated a laboratory technique for evaluating brakes-off wear and DTV generation. The present study includes 60 brakes-off dynamometer tests and compares the performance of three caliper designs that are Standard (current production), Standard + Increased piston retraction and Standard + Pad abutment shim spreader springs. In addition, the effect of applying double sided adhesive strips to the pad back plates on brake drag is reported.
