    Sram guide RSC lever sticky and slow to return

    Hi all, I've got some sram guide rsc brakes that are around 5 months old.

    Been working great, except just the other day I noticed that one of the levers is a bit sticky, harder to pull in, and it's also a bit slow to return back to it's resting position. Just feel tight kinda.

    If you pull the lever further away from the bars, it moves very easy and smoothly. So the lever itself feels good, it's only when it's pushing and pulling on the cylinder?

    I've tried doing a bleed, and also unscrewed the 2x torx screws and removed the lever, tried to clean it a bit and put back together.

    But still the same..

    Any ideas?

    Thanks
    Joel

    Let me know what you hear. I'm going to talk to the local bike shop tomorrow. Worried they will think I'm complaining about nothing as brakes still work. But feel all wrong.

    Any updates on this? My Guide R does the same thing. Works perfectly, but the lever is slow to return.
    I need a cool saying to put here.

    I had to send the lever back to SRAM via the local bike shop.. Returned 1x week later, repair sheet mentioned all new internals fitted to lever. Good now

    sorry for answering so late. The reason for that sticky lever may be sticky brake piston seals in the caliper. Put some dot on these caliper seals cycle the brake pistons a few times and see if it gets better.

    punish her by mounting them on her bike then. Make sure they suck some air in to make things worse
