Open the CIPO recordAbstract From the Canadian patent
A unique caliper is disclosed for use with a ring brake where the caliper is preferably fixed and two opposed pistons provide the force for applying brake pads to the brake surfaces. The caliper preferably includes internal conduits for hydraulically connecting the opposed pistons. Upper and lower parallel passages through the caliper simplify bleeding and allow the caliper to function as a left or right caliper. The brake pads include organic fibers disposed at an angle to the braking surfaces such that the ends of the fibers wear with the braking surface. The ring brake assembly has particular application for racing cars and in particular, small diameter wheel racing cars.

Why it's free to use
- Filed October 4, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 4, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 4, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
