Mickly Posted February 17, 2019 Share Posted February 17, 2019 So ... Ist learning point is that if you want to inspect brake caliper condition and want to remove the pistons, do it before you take the caliper off the bike so you can use the brake lever pressure to remove them.So that particular horse has bolted, and now I have a rear brake caliper off the bike with a stuck piston, the other piston moved with some air pressure from my stirrup pump, but this one seems stuck tight.Any useful suggestions would be appreciated.Ta.

fastbob Posted February 17, 2019 Share Posted February 17, 2019 Yes, stick it all back together, fill and bleed the system then pump the piston out . Time consuming but most cost effective. Quote Link to comment Share on other sites More sharing options...

Stu Posted February 17, 2019 Share Posted February 17, 2019 use these:https://www.sealey.co.uk/product/5637205018/motorcycle-brake-piston-removal-pliers I have a set of these and they work well but not had to remove any really stubborn ones yet with them so not sure how they will perform on those! Most are removable with compressed air but as you have found out pumping it out while it is attached is the best method Quote Link to comment Share on other sites More sharing options...
Via Posted February 17, 2019 Share Posted February 17, 2019 In absence of those I used some 90° circlip pliers (squeeze to open) with some electrical wrapped around prongs to do ones on ER5 (made same mistake ) Quote Link to comment Share on other sites More sharing options...

HiyaSorry for the delay in responding.Again, thanks for the offer, but I’ve got them out using a mate’s compressor ( just got home from his ).The operating area of the pistons look ok and the bores are fine, so a clean and paint of the caliper then reassembly is all that’s required.

Fozzie Posted February 19, 2019 Share Posted February 19, 2019 Those pliers can pull out stuck pistons with enough oomph as a foot note.Seized SV650 caliper, I got the pliers in there, nearly broke the adjuster screw getting it to grip as tight as possible. Caliper on a soft mat on the floor, and basically deadlifted the piston out It knackered the grip bits on part of the pliers a bit, but I just used them on a Blackbird this past weekend and they still work fine. Hopefully get a couple more years out of them, they're fairly inexpensive anyway. Quote Link to comment Share on other sites More sharing options...
Snod Blatter Posted February 24, 2019 Share Posted February 24, 2019 I like to take the rubber bits off the handles and then use a vice to squeeze the tool, that makes it bite good and proper! Then simply twist and pull on the caliper until the piston finally comes out and everything gets a nice coating of brake fluid, ahhh!
