BRAKE PADS FOR DISC BRAKES AND COMPOSITION BRAKE BLOCKS. DEVELOPMENT OF PHYSICAL-MECHANICAL AND CHEMICAL-ANALYTICAL TEST PROCEDURES FOR ACCEPTANCE TESTING AND QUALITY CONTROL OF BRAKE PADS

Provisional specifications for the acceptance testing of disc brake pads have been compiled in B 126/RP 1. For the final version of this document, further tests need to be carried out. Some of these, covering physical, mechanical and chemical properties of pad "composition" materials are described in the present report. Considerable variations in property levels due to material heterogeneity have been noted. The application of a number of the test methods studied as quality control and acceptance testing techniques seems quite feasible. Further experimental work will be required before correlation between the properties studied and the braking performance of "composition" materials is possible.
