    I bought both a clutch master cylinder cover as well as a brake master cylinder cover. Great fit and a little more chrome than the black one I replaced. Very much recommended.

    8/18/2023
    So to confirm, This cover can be used on both the front brake master cylinder reservoir and the hydraulic clutch fluid reservoir. Is that correct? This is for a 2014 HD Ultra Limited.
    JimmyD - Texas
    • Answer:
      Hello JimmyD, Master Cylinder Cover 42123-08 is just for mater cylinder, Part number 36700094A is the Front Clutch Master Cylinder Cover you would need for your 2014 Ultra Limited. Thanks blairmke

    9/18/2022
    Does HD offer just the gasket? I don't need the cover as mine is fine.
  • Question:
    3/21/2022
    Are these chrome brake reservoir covers (kits) available for a 2014 Ultra?

    Good afternoon, I can’t seem to find this master cylinder cover in black finish. I can only find I’m chrome. I have a 2018 road king special and the front brake master cylinder is leaking at the cover and I need to order a new cover and gasket. 
    Rick zap - Rochester MI
    • Answer:
      Unless your cover is cracked or warped, you may just need a new gasket. Be careful not to torque them down too tight - that can also cause leaks.

        Hello Rick zap, You will need to visit your local Harley-Davidson dealer for assistance with ordering a black replacement cover. Thanks H9FXE
