TREK SERVICE INFORMATION 14 February 2013
11. Rear Brake
The rear brake (Figure 11.1) is inside a cover, under the bottom bracket. There are two covers
from which to choose.
The rear brake uses a wedge/roller actuation, so cable tension is critical.
Before installing the rear brake, the aerobar should be installed with the rear brake cable and
housing in place. The bottom bracket cable guide should also be in place.
