As the title says, I didn't realize pulling the brake will get it stuck in a closed position when wheel and pads are removed. Now the reason I'm asking this previously asked question is none of the answers worked for me.

So what happened? Step by step description of the (rather long) process:

  • pads were worn off and started making funny noises, so I thought I'd remove them (first mistake)
  • pulled the brake lever without any pads (second mistake)
  • used the bike like this for a while
  • I bought new pads, then removed the (back) wheel
  • observed brakes stuck in a closed position, then I stupidly pulled the lever again (!)

I tried separating them with a wide range of tools, just they keep coming back in after a few seconds. Right after I stick something in between, push them apart from each other, if I wait a few seconds they are right back in the previous (wrong) position.

I'd like to know if there's anything I can do now, without bleeding the brake or anything I don't think I'm prepared for with my rather primitive tools.

Thank you all in advance for the answers, happy holidays & ride safe and fun!

EDIT: I just noticed this question and its answers. I will try to leave it overnight, then attempt a bleeding if it doesn't work (I'm aware of the trapped air possibility).

EDIT #2: I attempted to spread apart the pistons again, and succeeded, then I stuck a solid piece of wood that barely fit between them. Left it like this overnight + a few hours later, then removed the wooden piece and left it free for a while. It seems the pistons got back to their normal position and all I needed was a bit of patience.

Thanks to all the people who replied on the linked questions, they really saved me some experiments and possibly more. Cheers!

  • How did you go with bleeding? If those answered worked for you can you mark this as a duplicate of the one that worked, please. If not, add any details you can and we'll see what we can come up with. Thanks. – Móż Dec 30 '15 at 0:17
  • @Mσᶎ I have edited the thing, not sure if I should mark it as a duplicate or not. What do you say? (or if you have the power to do it and consider it appropriate, do it) – Victor Nițu Dec 30 '15 at 3:41
