Hi,dudes.I have recently noticed that my SLX levers got spongy.The "burning" term of calipers is over and that f..in feeling "where my brake power is" got its place.any suggestions? :D
Note; The Term "Mountain Bike" Is Incorrectly Used By Marketing People To Sell More Bikes To The General Public.

    Hi,

    Just had my brakes re-bled. I have Formula Oro, fundamentally, same thing applies.
    What I discovered was, a rebleed kit alone costs £40. Once the Dot fluid has been in the rebleed kit, the plastic/rubber breaks down, and needs to be discarded 12/18 months later, as often as you need to rebleeed. My LBS charges £40 to rebleed/supply of Dot fluid.

    I'd highly recommend gettin a pro to do the job, the Dot fluid is lethal. And, if your brakes fail, you're gonna break more then your bike!

    Happy riding !

    SLX brakes don’t use Dot fluid they use mineral oil and all you need to bleed your brakes is some mineral oil, a small length of clear plastic tube that costs 5p and a plastic bag.

    You can get an oro bleed kit for £20, and the parts don't spontaneously melt. Not trying to be funny but did you get that info from the same place that charges £40 to bleed your brakes?

    Northwind's got a point. My father had a home made auto-bleed thing he made for car brakes years ago using some plastic piping, a one way valve and an old chocolate spread jar.
    It's about as old as I am, and it working fine. DOT is nasty stuff, but it really really shouldn't melt your bleed kit.

    The bleed kits are usually just a syringe and a bit of silicon hose. Sometimes like with the oro/avid kits there's a wee brass fitting with an oring too. But there's orings in your brakes too which are brakefluid-proof, and the silicon hose is very fluid resistant (it may go cloudy but it's not likely to fail). The syringes might embrittle over time but it takes a while. The only part that you're really paying for is the brass fittings though- the hose and the syringes can be had for pennies. This does annoy me, paying £20 for basically 2 bits of brass that cost 20p each to make but, ah well, what can you do? I'm not a good enough machinist to cut my own and even if it was, would it be worth £20 of my time to do it? Probably not.

    you can get the brass fittings you are talking about from here :

    you can use aquarium airline for the pipe and the syringes are easy enough to get hold of online.

    the whole lot should cost around a fiver.
