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. There has been one reported incident of a single caliper brake failure with no injury or property damage.
Yep, that sounds exactly like what I experienced although I was able to remedy by flushing the caliper with spray cleaner while actuating the lever then installing new pads.
