Hopeless Calipers?

Postby norseman47 » Sat Mar 26, 2011 1:00 pm



Both of the front calipers on my GL100I has one seized piston each. I can't get them to pop at all. I've removed the calipers, soaked them in a parts cleaning tank, reinstalled them, but no good. The other pistons work okay. I can get the seized pistons to wiggle & turn, but not to moving out. I'm starting to look on ebay for replacements; in desperation...

I got them out! I read all the fine print forum entries & found the one by robertdawber who mentioned using a grease gun. I quickly got my grease gun, & hot-dang, they came out in minutes.

Thanks robertdawber!

What's he tell you to do fill the cavity with grease to push them out?

You click the grease gun onto the bleeder valve, open it a bit to let the grease in, and then start pumping.

Then clean all the grease out very, very well afterward!

Wow, how cool is that, what a smart way of doing it, I wonder if air pressure will also work, just put a clear hose on one of those bleeder air thingy nipple looking things and blow it out.. Has anyone tried that, I don't know but I bet it would work..But that grease gun is smart and safe too..And you get to make mud patties..Ha ha.. :lol: :shock: My way probably won't work and I'll get hit in the head or something like that.. :lol:

You can use air pressure - I've done this before, when the piston was ALMOST all the way out and jammed. However whereas an air compressor can generate perhaps 120 PSI of pressure at most, a grease gun can generate upwards of 5,000 PSI - much better at getting reluctant pistons to move.

There 2 things to pay very close attention to.First,clean the seal groove and the piston must slide easly to the bottom of the casting without the seal.
