I'll try some 3-in-1 overnight and try again tomorrow.

The other caliper is in Gunk now with seals in still...if I take them out now would they be ok to reuse?

No dishwasher, I'll have to do it the old fashioned way

What you are supposed to do (if you had read my posts on the matter ) is do one side at once, so when t'other is back together you move to the other side, bleed it up (ish) and use hydraulics and a G clamp to pop them out.

Most emphatically DO NOT REUSE THOSE SEALS. It is not worth risking it now you have possibly damaged them with degreaser.

I cant use the hydraulics system on the bike (well I could, but its a bit too late now...) - I;d have to refit the whole lot and to be honest I'm too lazy. Its cold out

Copper banjo washers are like 20p so I will get new ones anyway.

They arent going back on til spring, so no real rush.

He is on about the rubber boots, silicon grease is OK on them and on seals but it is IMO too slippy for seals. Rubber grease is good.

Do not use brake fluid on them, haynes is full of ****. The brake fluid crystallises, expands behind the seals and actually causes brake drag. Better to put them in dry than use brake fluid.

You can reuse banjos washers unless they are damaged for whatever reason or refuse to seal.



To get your piston out, put a big cable tie or better yet a jubilee clip around it and use pipe grips over that.

Might give it a try next, so far this pot has done probably 50 calipers and there's plenty left.
