    Oil on rotors

    I hit a couple of parts on my bike with wd40 and I think a little got on my front rotor. I took my bike out for a ride and the front brake and barley any stopping power. What's the best way to clean the rotor?

    Thanks!

    use automotive brake clean, or ispropynol alcohol
    best done with the rotor off the wheel, so whatever you use doesnt damage paint or seals

    it will not work at all and squeal LOUDLY at first, but will get back to normal after the first several braking applications

    Having been through this a few times myself obviously you have to clean the rotors, that's the easy part, but now the pads are contaminated, the oil is baked into them now because you ran them. So after cleaning you have only two options (1) throw the pads away and buy new ones (2) if you want to re-use the pads, take an old hotplate and bake those pads for 10 minutes wiping away the oil that rises to the pad surface every few minutes, then sand them in a figure 8 pattern for 10 seconds and go ride!

    I never apologize. I'm sorry, but that's just the way I am.

    Why were you spraying WD40 on your bike at all?

    Cleaning the rotors gets the oil off the rotor; it doesn't get it out of the pads. When you apply the brakes the oil which is contaminating the pads is heated, thins and soaks in further. This is why heating them over a high flame, until the black smoke has gone, will sometimes work at decontamination. Brakes are a safety component and I would only try once to burn contaminates out. If that doesn't work, it's time for a new set of pads and a lesson learned.

    Which brakeset do you have? From where exactly is the fluid leaking?

    1 - Keep WD40 away from your bike from now on.

    2 - Clean rotors with alcohol.

    3 - Buy new brake pads.

    4 - Remove head from ass next time LOL
