An improved disc brake pad backing plate assemblage of the dovetail type wherein dovetail end strength for resisting deformation is increased by the use of a special secondary backing plate member in conjunction with a primary backing plate member having a dovetail for mating engagement with the dovetail groove in a disc brake holder. The resultant absence of dovetail end deformation facilitates removal of the disc brake pad from the mating dovetail groove.

Why it's free to use
- Filed September 2, 1994 and granted August 3, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 2, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 2, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
