Yeah that's good manual with pics you have there Dermot. I haven't replaced the o ring on my brakes but I know this is the source of losing power if bike sits idle for longer period of time. The leak is so tiny that when you use bike often you might not notice it at all as the fluid is burned once you start braking. I think on newer shimano brakes this is sorted now but I spent months wondering why the bloody brakes lose power and it was so frustrating as you want to go out and realise brakes are not great etc.

See below from Genevieve Filewood, a master’s student of Sport and Exercise Nutrition at Ulster University who is looking for vegetarian athletes for a research project investigating the nutritional knowledge of vegetarian athletes.

"I am looking for male or female participants,living in Northern Ireland/Republic of Ireland, between the age of 18-64 years, who currently follow a habitual vegetarian diet, engage frequently in power-based or endurance training/sport (e.g. weight training, long distance running) and who have not completed this same study questionnaire in the last 2 previous summers (2018 and 2019).

The study will involve one primary component:Completing a questionnaire consisting of initial screening questions, demographics and assessment of nutritional knowledge.

Those who complete the study can leave their email address to be entered into a draw to win £50/€50 vouchers

If they feel they fit this criterion and would be interested in taking part, they are requested to click on the following link and complete the questionnaire:https://redcap.science.ulster.ac.uk/redcap/surveys/?s=XTX44RF73X

The questionnaire will take 20-30 minutes to complete. It is entirely up to them if they want to take part.Thank you for taking the time to read this, Genevieve Filewood.

This study is supervised by Dr Julie Sittlington and Dr Pamela Magee. They can be contacted at jj.sittlington@ulster.ac.uk or pj.magee@ulster.ac.uk. The use of email to recruit participants for this study has been approved by Ulster University Filter Committee."

I am stupid, but did see this post - http://blueliquidlabs.com/repairs/solving-that-brake-squeal/


What o rings do I need and where to get them?
I initially thought it was on the piston, but from the pics shown in the aboce post, it looks like within the caliper.  It does seem to look like that's where my leak is coming from (stain of oil in that area, on two calipers).


Any idea what the size material of these o rings is?  And where to buy them would be great.


EDIT:-
sorry, I am stupid, these are the correct ones?  https://www.ebay.co.uk/itm/141455807147?_trksid=p2060353.m1438.l2649&var=440603744128&ssPageName=STRK:MEBIDX:IT


edit AGAIN:-


I am confused from teh topic quoted at the top, these are the calipers I have (M765). I do need the piston one then I think.


What about if you have a Shimano 1 piece caliper thatís leaking and squealing? Thatís definitely happened before. Models Iíve seen this happen to include the M765, M775 and even the M800.

Well speaking dollars was the first hint.


So I checked their first post and saw that it was typical of a spam bot's first post. If they post an ad as their first post then it'll raise suspicion straight away and get deleted, so they tend to post a fairly generic message, often copy/pasted from another forum, or even the same forum. Then they come back a few days or weeks later and if their account hasn't been banned they go ahead and post a link to their site.

This one was extra sneaky though. This post didn't have any link in it. So if a moderator reviewed it, it still didn't look like spam and wouldn't get deleted. But then the spammer came back later and edited their post adding the link  to their site.


Also I just googled the user's first post and it was indeed copied verbatim from another forum.

99% sure ye're talking to a spambot lads.
LOL. Will we be awarding spambots for their post count come Xmas?


Checked both posts made by this user, first now looks dubious, second is defo not models of bikes we know on this island....  Curious how you spotted it.
