    I know I shouldn't ask, but I absolutely can't get my brakes to stop squeaking

    My front brake only. Using kool stop salmon cartridge v-brake pad. I've cleaned the rims, sanded the pads, adjusted the brakes all different ways, adjusted the toe in, switched the front and back brakes (non cartridge), I've let them wear in for over a month, and they're still loud.

    Once, I got them to almost stop, but they would squeak when I got to low speeds, and sometimes they stop when its raining, sometimes they keep going in the rain, or they always squeal. I don't know what to do besides try ordinary black pads again.

    I put a very small amount of talcum powder on mine. It worked.

    How's your toe in? See this web site for detailed info about brake noise: http://www.bikeman.com/content/view/704/115/

    v brakes.

    I'll try the talcum powder...

    They're Avid SD-3. Are those too flexy? should I buy stronger brake arms. I think I might need a brake booster too... Because I can see the fork flex when I apply them really hard

    I think the brake booster is worth trying if your fork is visibly flexing during braking. If it's flexing that much, you'll notice an improvement in braking performance with a brake booster. Might stop the squealing, too. Or maybe not.

    What rims do you have, and how new are they? I've had problems with salmon-color pads squealing on new rims. I switched to black pads for a month or so to break in the rim, then went back to salmon. No more squeal.

    +1 on the toe in. The front of the pad needs to hit the rim first.

    As strange as it may sound, try a dab of carbon assembly compound ("grit paste") on each side of the rim, followed by riding around dragging the brakes to burnish it into the metal. This has stopped the unstoppable squeals in nearly every instance I've tried it.

    Because the pads are very soft. Harder brake pads like say some generic drop in refills will not do this at the expense of braking performance. I suggest the OP to try a different refill .

    I'm really surprised the salmon pads are squeaking... usually they make a nice grinding sound on your rims - considering they're filled with particles of iron.

    it's the particles of road grit that gets packed in them. clean your pads if you care about your rims.

    One thing about kool stop salmons in my experience with them: they don't make grinding sounds, even in the worst conditions. They're every bit as likely to squeal as any other pad, maybe more, but relatively speaking, they're easy on your rims. No grinding.

    My Avid BB7's squealed every time I pulled the lever until I replaced the stock pads with (drum roll please)......Kool Stop organic pads.

    Yeah, ditching the bb7 roundagon rotors for the g2 clean sweep helps also...

    The "Jobst Brandt" formula for this is Bon Ami cleanser and dish soap. It's cheap and it washes off with water.
