A Guelph, Ont., manufacturer of brake pads is raising concerns over “huge amounts of Chinese product dumped into Canada” particularly as there are no mandatory Canadian standards for replacement brake pads.

In simulated panic stops during ABS Friction’s tests of competi­tive products, chief executive Rick Jam­ieson says some pads “self-destruct — the brake pad will literally break down.” Many also contain undisclosed asbestos.

“In China, the people can make very high-quality goods, and inevitably there are some products of inferior quality,” said a spok­esperson in the Chin­ese consulate.
