    bleeding ?

    i've never had hydraulic discs before and was wondering how often they need to be bled ( once a season with a full tune or just when they feel bad)? also is bleeding my own brakes something that i want to do or should i leave that for a shop. i do almost all of my own tuning/maintanace on the rest of the bike but never have bled brakes how hard is it? let me know what you think.

    once a year

    or if you feel there is air in the line, the air compresses unlike the fluid so if there is air in there the lever will feel squishy. Bleeding is not complicated, buy a bleed kit from your brake manufacturer and it will come with good instructions. Basically you squeeze fluid from the caliper up through line and out the master cylinder on lever until you get no air bubbles.

    Depending on your riding style, type and milage you will need to replace rear pads 2x as often as front...keep checking your pads if they get too low they will gouge your rotors. Not sure of a rule of thumb but i replace em when the material gets less than a 1/16th of an inch.
    Hydro's are the best, enjoy
    good luck with em

    I'm using a set of brakes now that are 2 1/2years old without the need for a bleed. The set before were 1 year and no bleed. Unless there is a fault, there is no "need" to bleed.

    Yes you should learn to do your own and then you know the qualifications of the person doing them. Otherwise it's a crap shoot.
