How do I get this out

MDK · DTR Legend

in most cases reconnect it up to a lever and bleed and pump it out is the best way hydrolic power

or brute force put it in a vice or clamp get something to grasp the piston that will not damage it and twist and turn wilst pulling it out wards .

ToySoldier · DTR Legend

that to me that looks like your pads fallen out and the piston has rubed on the disk?

ezegreenfingers · Guru

Yep that's exactly wat happend will I need new piston and seals or can I get away with using this still

ToySoldier · DTR Legend

haha iv had mine do it more then once the rubber seals pop out iv pushed my seal back in both times now and been able to keep useing the caliper lol but you will need to bleeed it back up and jump on that peddle that should do it

Piston won't budge screw wont budge what the fuk what way the screw on top ment to unscrew

MDK · DTR Legend

still looks usable if the sides was damaged diff story but the top damage is no real problem once you get it out smooth of the top be as good as new .

in future leave it all conected to break lines and use the breaks own power to pop out the piston .

some ppl use air also or even a grease gun lol look on yube for other methods

MDK · DTR Legend

yeah those bleed nipples always get stuck and tend to snap off ? if it snaps I drill it out re thread the hole and seal it with a bolt .

I wasn't gona take the piston out I was looking to push it back in is this possible

MDK · DTR Legend

should be easy to push back in lay it down use a peice of wood to force it down or you have a vice or clamp ?

ToySoldier · DTR Legend

you need to do this step by step and hopefully it will work like iv manged
you need to bleed it up put pliers or something so the piston doesn't move.

then gently push the pedal then with a small flat headed screw driver push the rubber seals back in then try and push the piston back in

Ok how do I bleed the brakes what ways this screw ment to undo dam I'm in a mess

MDK · DTR Legend

if you cant un do the bleed nipple just leave the brake hose a little lose keep topping up the fluid res and pump away till you see no more air bubbles or you think its free of air then wilst holding the lever down tighten the hose bolt and see if that works . ?
