Topic: brake pad stuck inside caliper!!!!!!!!!!!!! HELP!!!!!!!!!!!!!!!!

[Short Round]

My brake pad is stuck inside the piston side of the caliper (74 CB550 K0).  I have tried a few methods to get it out but to no avail.  Any tip would be great, this is the last thing to be fixed before I can get back on my bike again and it is killing me that something this trivial is having me wait.  Help please

How did it become Jammed -??

Squirt some wd40 or INOX inside the caliper around the piston, let it soak for a while, then try and pump it out with quick sharp hand action on the brake lever.

You can also remove the caliper, connect up a grease gun and pump it out (have not tried this but others say it works)

I have used compressed air - put the caliper face down on a towel and it will pop out, with a bang.

good luck

thanks man I wioll try to do the compressed air method in the morning.  For right now I am off to bed after staying up all last night cleaning and polishing my fork lowes and whole front end while it was off, and then having to work tonight till 11.  I'll keep you updated on how it goes.

I have the same problem with a stuck piston. I did manage to get it out level with the caliper face by slapping it repeatedly on a wooden bench. But it won't go the last 1/4" or so...and the bleeding screw snapped off so that will have to be drilled out...   

I found a junkyard caliper on eBay; I'm hoping that works out better...

I've had the same problem, and used three different methods - they all work.
Fist off, I've tried the grease gun method, and it works a treat. As I don't have access to compressed air (exept for the local service station), this method was my first attempt, and is the quickest and easiest in my opinion.
Compressed air works great, but make sure you don't aim the loaded caliper at any innocent bystanders! The shoe and piston will come out alarmingly far. Use a rag to cushion the impact!
Third method was just patience. I just held the caliper in one hand, and tapped the outside gently with a chisel handle (as I didn't have a plastic hammer), moving all around and across the top of the piston chamber. Eventually the pad was out far enough for me to do a little gentle levering on the pad sides, then back to the tapping.
Hope this helps.

I've used the grease gun method twice, quick and much safer then compressed air.

Chris: Did you get it out?
