    Sasakyan namin naka open parking. Ngayong tag-ulan puro talsik at makapal na ang kalawang sa disc brakes. Bihira din gamitin, kaya hindi na "sand-off" ang kalawang.
    i think it's a bad idea.
    even if WD40 offers only the barest minimum of so-called 'lubrication', it may still be enough to make you lose braking power, resulting to bumper damage.
    if the opposite happens naman, that is, the brake rotor surface becomes 'grabby', it'd be an uncomfortable drive until the layer strips off.

    kinakalawang yung disc brake rotor?
    i wouldn't worry about it.
    the amount of rust formed is so minimal, it will take many years and many tens of thousands of kilometers, for them to become replacingly thin.
    and it's so easy to clean them! the thin layer of rust is completely removed after two or three mild applications of the brake pedal.

    then it came to me,
    in the olden days, we would use kerosene (gaas!) to de-grease and clean bicycle chains and other automotive parts.

    when we were kids, dad would teach us to degrease and clean our bicycle chains, using kerosene and paintbrush.
    this activity actually prepared us for the more-daunting acts of degreasing and cleaning our cars' parts later on in life.
    I also remember back then wala brake fluid ang gamit ni erpat para palambutin ang kinalawang na nut para maipihit.

    we used to use light machine oil, i.e., singer sewing machine oil.
    dad would lather it on, then take a coffee brake while the oil penetrates, and come back after some minutes to an hour.

    Not the best solution to your problem, for two things:
    1. Brake pads are porous materials and can absorb oils and reduce its effectiveness. A little oil contamination will likely be alright, but still, never a good idea to actually spray them with it.
    2. I have tried using WD40 to prevent surface rust (on my chrome drum set a long time ago) and it barely works to protect it. What is effective is to use WD40 with Scotch pad to remove surface rust on chrome and metal surfaces. In this application, WD40 works as a lubricant and detergent.

    It's still best to drive your car around the block every now and then to clear up those rust build-up.

    Why not use brake cleaner on brake pads and discs? Mura lang naman yun.

    I donít mind the rust on the brake discs specially if you park your car outside. It will just rub off once you use the car. Unless of course, the car has not been used for months.

    Salamat dr. d oj88 Egan101. Hindi din pala kabilis ma wipe off ang wd40 sa brakes. Nawala din sa isip ko na porous ang brake pads at maka absorb ng fluids.

    Naisip ko nga sa normal service pinapaliguan ng brake cleaner ang rotors at drums. Pero naka baklas pala pads noon, at ni wipe off after.

    After mga 2 weeks kasi ng ulan sa labas. Nakaka ilang kilometers muna bago mawala ang kaskas na sound ng rusted rotors tuwing brake application.

    Mas frequent nga siguro i ikot ang sasakyan.

    don't mind the kaskas.
    basta hindi mahina ang breaks, ok na yan.

    Sometimes the rust can cause the rotor/drum to seize up. People familiar with this would hear a loud "tug" as you start moving the vehicle. It can be unnerving the first time you experience it.

    it was a bit un-nerving, the first time it happened to me.
    kaunting urong-sulong lang, to dislodge it.
