    Upset HELP NEEDED BADLY!!! Can't ride: Terrible noise and no power on older Saint

    - I just posted this on brake time forum but as I'm in such a distress I'm spreading ti here as well, so sorry for that -

    SO my front brake - older Saint - is making noise so bad I don't want to go riding. So that's pretty bad! It's not the usual disc brake noise. it's something much louder. It also doesn't brake well. My rear brake is as silent and as powerful as it should and I love it.

    The weird part is I have changed the pads and the rotor and have re tightened the caliper many times so the position would be correct/different.

    One thing I haven't tried though is to try another wheel with the same rotor..

    But if it's not the pads, rotor or wrong position of the caliper what could it possibly be?!? Anybody had or heard about similar issues with disc brakes or specifically with the older Saint model?

    Hope i can fix this soon as I really love the brake when it works and I want to go riding... NOW!!!

    Did you try bleeding it?

    Without hearing the noise and looking at it, this is going to be difficult to diagnose over the internet.

    Describe in more detail what you've done so far. How did you alighn your calipers?

    My hunch is that its something with your specific setup rather than something common to old saints, but that's just a guess

    Actually, I think a seal in your caliper is leaking brake fluid on your pad and rotor. You should either rebuild your caliper or replace it

    Can you see a leak near the piston?

    Contaminated pads and rotor, possibly from a caliper seal leak or line leak. Could also be external contamination like lube overspray or riding through a contaminated puddle. That happened a lot in PA where the dirt bikes were out.

    New pads (or the sometimes effective "baking" of pads) and a rotor cleaning is in order once you figure out where the contamination came from. Lots of advice can be found on how to do these things.
    Don't you hate it when a sentence doesn't end the way you think it octopus?

    are you sure the wheel is mounted right and spinning true? I've had some awesome sounds from my rear brake before when I didn't get the axle seated correctly so the rotor was scrubbing the caliper.
