Caliper piston won't wind in

Harsh 
It might be harsh, but having looked at RR76’s posting history it’s hardly unfair.
(PS - i was in the "get someone in to sort it" camp early on in one of his other threads.)The words "Horse" & "Water" spring to mind.
I can't decide if giving him more info/assistance will improve matters or make them even worse.
RR76 said:
it's not needing rebuilt, it's a problem at the seal/piston interface. The rest of the caliper is fine.
You have no idea whether it's fine. RR76 said:
I know your meant to use red rubber grease and I have ordered a tin so I'll see if that fixes it.
You aren't supposed to use red rubber grease on the O ring seal, and greasing the seal is unlikely to cure your problem.RR76 said:
You guys should have known the answer to this at the beginning that is was likely at the seal where the problem was.
It either needs a new seal or the correct grease. It's not rocket science.
The O ring seal not being greased is not why it was so difficult to wind back. If you think you've got to the bottom of the problem, have another think. It either needs a new seal or the correct grease. It's not rocket science.
Given all the other grief you've given that caliper at this point it's impossible to guess what's wrong with it now. If you've stripped the piston down and cleaned it then tried refitting it dry that definitely won't be helping now, but clearly there was some other problem in the first case and it wasn't anything to do with the O ring needing grease.

There's no need to adopt that attitude, but for the record, the main seal in which the piston moves should be lubricated with brake fluid only. The red rubber grease is supposed only to be used to prevent corrosion of the exposed parts of the components around the rubber dust seal.
Do you think a new seal will fix the problem?The caliper is seized due to water ingress and from an inexperienced DIY perspective it is scrap. Do not attempt to refurbish it, buy a new or reconditioned caliper.
If you had shown the picture of the ripped outer weather seal first then you would have got better advice.
I would strongly advise you get a mobile mechanic in to complete the job as bleeding the system is equally if not more difficult.
And a word of advice; NEVER criticise or blame those who are trying to help you.

Check the grove that the o ring sits in, it'll probably have a build up of white alloy corrosion. Give a good scrap out and clean. Then reassemble with a dab of red rubber grease and seal, bleed it up, double and triple check for leaks! Then check its not binding up etc
I have done this thoroughly making sure not to damage the metal, there was buildup of solidified grease, dirt etc. It's clean and hasn't made a difference, I have a new seal ordered and if that doesn't work I'll bin it.Drive it fix it repeat said:
I now think this is a wind up. Waste of time trying help someone who is too stubborn to listen. I would have been willing to give you a hand if you were local but your whole attitude stinks. When you crash try not to hit anyone else.
New seal in, used the red grease that came with, piston winding in like a charm.RR76 said:

Show us a photo then?You've done well, you were only asking yesterday afternoon if a new seal would help. You've already obtained one, fitted it and got everything working. Impressive progress from a man who didn't know whether a rear wheel should rotate a couple of days ago.

I ordered the seal a couple of days ago, I'm surprised it arrived so quick. And you get 2 boots and seals in the pack that's why the photo shows an extra boot and seal.

This means this caliper hadn't been working for some time I assume as there's no way I could have caused the boot to slip off and the piston to seize on the seal by just slipping off the caliper from the guide bolts.

Confirmed troll. You didn’t know how to wind a caliper back but have a caliper wind back tool. Or more likely, you just googled a picture of a caliper.
I think you need to give your head a wobble, the guy obviously doesn't know a lot about cars and is trying to learn, is it a done thing now to call people out as trolls or just the usual full of kn*bheads PH way now?Jazoli said:

This forum is usually free of the w@nkerish knobbism that infects a lot of the other forums on this site but its gradually seeping in, which isn't a good thing.

I think you'll find the tone changed somewhat when the OP himself gave this reply to people trying to help him:

I knew the principle of winding it back and have the tool but it wouldn't wind back that was the whole point. Nobody seemed to know the seal was the most likely problem.https://pasteboard.co/JFcWWXX.jpg

I have, and its fairly clear that he is just simply asking a question on each different thread rather than just have one running (which is not ideal but..), not everyone is mechanically minded and I can say that lots of people I know wouldn't know how to rotate a wheel, it just seems the PH way to pile on someone, be aggressive and criticise and there is no need, do you really believe that someone would take the time to troll on 5 different threads? I don't.
I suggested on one of his threads to get someone who knows what they are doing to look at and sort it, he has obviously decided not to and fix it himself which is admirable but maybe misguided as I also pointed out that brakes are rather important and maybe not the best thing for 'my first repair'

I've stripped down two engines and a gearbox in the past but that's over the last 15 years so the knowledge is not readily available but comes back quick.I suggested on one of his threads to get someone who knows what they are doing to look at and sort it, he has obviously decided not to and fix it himself which is admirable but maybe misguided as I also pointed out that brakes are rather important and maybe not the best thing for 'my first repair'

I admit asking if the rear wheels turned the same as the front was very stupid in hindsight. Can you imagine the scene if you were trying to coordinate two sets of wheels turning, it would take some skill.

Indeed. Well played! This of course means he really is messing around with his brakes when seems to know little about them!
