Open the CIPO recordAbstract From the Canadian patent
A brake drum for mounting on a wheel hub has first and second drum pilots for facilitating proper alignment when installing the brake drum on the hub. The first drum pilot is configured to engage a first hub pilot and the second drum pilot is configured to engage a second hub pilot. When the brake drum is initially moved toward the hub during installation the first drum pilot engages the first hub pilot and the second drum pilot is sufficiently spaced away from the first hub pilot to prevent the front edge of the second drum pilot from being caught on the corner edge of the second hub pilot and the drum becoming eccentrically mounted.

Why it's free to use
- Filed April 23, 1998 and granted July 24, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 23, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 23, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
