Like an idiot I sprayed degreaser on my discs the other week thinking id be doing them good. Since that incident my brakes hardly grip! I bought some disc brake cleaner but not much better. Wht has degreaser made them like ive oiled them? Is there any rescue I can do to my ice tech pads?

Might sound daft but I thought degreaser would have made them cleaner and grabier!

    New pads and clean the rotors with isopropyl alcohol.

    Thougt as much.

    Is that alcohol stuff 'Muc offs disc brake cleaner'? Or can you buy it cheaper as what you stated. Still insure why degreaser would make them greasy though?

    most degreasers are oil based,a mate boiled his pads after getting oil on them and said it worked,but it didn't for me when i got brake fluid on some,as "cooldad" says it will be new pads

  • spray muc off on your pads (the bike cleaner one) rub the pad faces together and then wipe off the cleaner with a dry, clean piece of kitchen roll. This usually saves pads, but if they are bad, you will have to repeat it a couple of times to lift the contaminants off. You don't need to put pads in the oven etc to get them working again.

    He's already added enough sh1t to the pads.
    New ones, call it education, and don't use anything except a bit of clean water in future to give them a rinse.

    Cheers but tried all that to no avail. They did get marginaly better, they now feel like Elixirs but want SLX's back ;)
  • if you've tried that already. The pads a FUBAR and you need to buy new. No need to shell out for ice-tech pads (they're stupid prices and don't make much difference anyway). Go to somewhere like uberbike and get some good pads that are miles cheaper

    The muc off trick works if pads aren't too contaminated. It's a little trick that people use as a fast fix, so you're not really adding anything else to the pad that will harm them and cheap as people usually have muc off etc laying about anyway

    I got brake fluid on my discs the other week or thought I did and after not being able to find any brake cleaner locally I tried citrus degreaser out of a bit of desperation and it certainly seems to work, brakes still grab well and as a bonus my elixirs are quiet again too.

    DOT Brake fluid is hygroscopic, which means you can clean it away with clean water.
    The same is not true of mineral oil.

    Ideally, keep any and all sh1t away from your brakes. They don't need cleaning, degreasing, or lubing! - it does happen, people have sprayed WD40 to stop them squealing.
    Rinse with water to flush mud or grit out and leave it at that.

    Well I will never use degreaser on my discs again. Expensive mistake.

    I find using soapy water on my discs helps, just make sure you rinse

    IPA is the only thing I'd clean discs with.

    Pads, well, if they're contaminated, then, new pad time.

    If they're glazed from dragging or rubbing, then sanding works ok, but if contaminated they'll just get more crap on the discs again.
