I bought second hand SRAM RIVAL hydro shifters 1x11 (not from here). The rear brake works fine but the front quickly weakens and the pads get shiny - bleeding fixes it temporarily but braking quickly gets spongy again.
I'm guessing there is a leak somewhere on the system although it's not clear where. Is there a bike shop/ mechanic in London (preferably north!) that might be able to have a look a fix it? I've seen a few videos of replacing the rubber seals but not sure I'd be capable of it myself...
