piston not returning to the hull

One of the pistons on my Hayes 9 is not returning to the hull. I have just put a new set of pads on.
Is this just a case of bleeding my brakes? taking them apart and cleaning the,? or is the problem a little more complex?
any suggestions?

If you had mechanicals this never would have happened. Mechanicals are field serviceable, which is another reason they are superior in every way to your hydraulic brakes

My guess is that when you changed pads, you tapped the brake lever and this is why your pads are now too close together. You can bleed the brakes, OR you MAY be able to use the round end of a open end wrench to put the pads back into place. Pull the pads, and use the round end of the wrench to push the pistons back into place.

Good luck!

Just pry the pads apart with a screwdriver if they are too close together.

Stiff putty knife is another handy tool for that.

Hull...........I have never heard that term in regards to disc brakes. Another word for caliper?

Oh. I've found V brakes really suck in the snow. They freeze and your rim gets ice on it and they go down to about 10% of their normal dry function. it blows. Makes me really need disc brakes.

What a naiive ice cream sampler I must be. All ceramic I've eaten off of is glazed. Stupid, STUPID, STUPID ME!!!!

LOL. Ok, well that's good to know that I don't necessarily have to use disc brakes if I want to ride in the snow and ice. Disc brakes always have seemed like something I would just end up braking, or something I really wouldn't wanna pay/deal with in terms of maintenance. My V brakes right now are so lame. Maybe I can just get some new rims and some heavy duty V brakes and call it a day?
