It’s certainly early days for road and cyclocross bike disc brakes, and today TRP Brakes joins Shimano and SRAM as the third company to recall select models of their disc brake calipers. All TRP dual piston Spyre and Spyre SLC disc brake calipers are affected, with no injuries reported, but TRP is issuing a voluntary recall on all Spyre calipers. Full recall notice below.

Tektro USA/TRP Brakes has issued a voluntary recall notice for customers and retailers to stop riding and stop selling Spyre and Spyre SLC mechanical disc brake calipers. We have also filed a report with the CPSC in accordance with their guidelines. We have identified a specific condition that could result in failure or one or both of the brakes when installed on a bicycle.

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 applies to approximately 4000 brake calipers sold from April 2013 to December 6, 2013. There has been one reported incident of a single caliper brake failure with no injury or property damage.
Customers are asked to take their Spyre or Spyre SLC’s back to the original place of purchase or to contact Tektro USA/TRP Brakes Customer Service to arrange a return shipment. All Spyre and Spyre SLC calipers will be replaced free of charge.
