brake piston removel
« on: September 09, 2019, 02:43:53 AM »
Made the mistake of not pumping brake to remove piston before removing from bike. So I used compressed air but it did not work did not have fitting for grease gun but later I read of a guy said he ground down bleeder to fit grease gun on. So what I used was a bolt and a nut I cut the head off a bolt making it just long enough to fit inside of piston and I held on threaded part and loosend nut to wedge against piston. made it as tight as I could then I was able to grab bolt with vise grip to pull piston out. Put the caliper in vise then i used a heat gun softend up  seals nicely and was able to pull piston out. Hope this helps

Well done.

Have a look at this link for grease gun adapter by dieseldoc. Worth having in the tool box.

My normal grease gun end fits the bleed nipple spot on, have used a couple of times now to remove seized pistons... ;)
