My wife's 2012 Cross Country Tour (XCT) has just started exhibiting a weak rear brake. When the rear brake pedal is pressed, there is some braking action but not as much as there should be. If I compare it to my 2012 XCT, her bike has significantly lower rear braking action. I have checked the rotor and it is fine (proper thickness and no scoring). I have checked the fluid level in the reservoir and it is full. The fluid is fairly new and not discolored. I have examined the brake pads and they are practically new with large amounts of the wear grooves still present. This reduced braking action occurs starting with the very first press of the rear brake lever so it is not overheating of the fluid. When the rear brake lever is pressed, it has firm resistance and does not go down real far as it might if there was air in the system.
Any suggestions for possible sources of this problem would be appreciated. Thanks.
