    Update: Grabbing Brakes solution

    I received my brake disks that I ordered a few months ago but have been too lazy/busy to install them. I'll get to it soon. In the meantime I wanted to mention that I've started keeping my car in the garage lately and just being out of the moist evening air has greatly reduced the amount of rust that forms overnight. I seldom have to do the "Cleaning" procedure. Of course wet brakes in the rain is still an issue. I'll install the slotted aluminum disks soon and let you know how it goes.

    (I wonder when Toyota is going to admit that the older models have the same problems as the 2010 Prius.)

    Why must people seem to make things more complicated then they really need to be?
    You have brakes that rust... Why? Because you don't use them near as often as if they where a non hybrid. So to clean the rust off... Wait for it... Use them. Simply do more hard braking more often. It's not hard to determine when you are going from regen to friction braking make sure a time or 2 in every trip you break harder.

    Because it is fixable. Possibilities include: Using alloy metal that doesn't rust or rusts less. Some kind of cleaning system that removes the rust. Shields that protect the disks from water.

    I'm only making a big deal because I think it sucks and something needs to be done. Everyone is welcome to their own opinion.

    Re: Update: Grabbing Brakes solution

    So you have the disks in your hands, can you confirm they are alloy? When reading the manufactures web page they appear to be steel with one of two types of plating, granted they are slotted which makes them superior to non slotted. I also note the manufacturer suggests using metallic brake pads for best performance, I can't imagine metallic pads being used on alloy disks, or rather I can imagine how quickly the disks would disentigrate...

    OK! Here's the long awaited result...
    I don't know why I waited so long to put the new disks on. It only took about 10 minutes per disk. Take off the two bolts that hold the caliper on. Swap Disks. Put the caliper back.

    Here's a picture:

    It has significantly reduced the amount of slippage due to corrosion but has done little to help when wet. Well. 50% improvement is better than nothing. Glad it doesn't rain much in San Antonio.

    Overall I think it was well worth the money I spent. I would do it again.

    Oh. And get yourself a color chaniging dorbell while you're at it.

    not to burst everyones bubble, but slotted rotors are a performance mod used to cut any glazing off the PAD, so fresh pad material with best stopping friction is always contacting the rotor.
    slots do nothing to clean the rotor.
    slots are generally accepted in high performance applications to maintain maximum stopping power from intense heated pads/rotors.
    BUT this slot cutting action sacrifices pad longevity, not a concern in race setting when brakes are replaced frequently.
    on a street car slots are usually a waste, because you never get into that high performance range, especially on a prius;) lol
    all you are doing is skimming your pads continuously, it will just shorten pad life. no real performnce gain.
    maybe if you are lucky the rotors are an alloy that will resist corrosion/rust better :)

    Good suggestion there and I won't bother to argue the rest of the thread. I may do a something like this periodically because, after all, most of us take pride in NOT having to use the friction brakes much...

    It's all about the alloy. The slots are just a bonus to help water escape.
