Tektro USA has issued a voluntary recall notice for TRP Spyre and Spyre SLC mechanical disc brakes.
"We have identified a specific condition that could result in failure or one or both of the brakes when installed on a bicycle," said Tektro in its recall notice.
"The Spyre caliper uses a dual piston design in which ball bearings move within opposing ramps. We have discovered that in a specific scenario, the balls can be forced from the ramps if the actuator arm is fully activated to its stop with excessively worn or no pads installed. The effect is that the one or more of the balls can jump from its position within its respective ramp, resulting in a reduction or loss of braking force."
The recall affects roughly 4000 brake calipers sold from April 2013 through December 6, 2013. Tektro has recommended dealers to stop selling the brakes and riders to stop using them and return them to their local dealers for a free-of-charge replacement.
