SRAM® HydroR™ Lever Service
SRAM® HydroR™ Lever Service
Perform this service if you have forward or backward play, or rattling in your lever.
Prior to servicing the lever, record the lever placement on the bars and position of the reach so you can return the product to these settings. For an
externally routed hose, detach the hose from the bicycle frame according to the bicycle manufacturer's instructions. For an internally routed hose,
disconnect the hose from the caliper before removing the hose from the frame.
