Brakes, front tire, chain

[stossboss_gaming_and_news]

So while I wait for my tach cable I'm working on some other components that need love.

I changed brake fluid and the front brake is nice and firm but as I was looking for the leak in my front wheel, there is quite noticeable drag as I spin it - I don't think I did anything wrong replacing fluid but I hadn't tested it forehand. Is it most likely the caliper needs cleaning/rebuild?

As for my front wheel, I think I found the culprit as a pool of white foam builds up on a portion of the rim - it has always had a slow leak since I had it but I just filled it every time I rode. The tire is in serviceable shape otherwise, is it most likely that the bead is set badly or rim damage - if so will putting some sealant on that portion alleviate the problem or is that not recommended?

As for my chain... I'm confused because I thought the pins were supposed to roll around - about half do and half don't so I order a new chain + sprockets, I got the DID 630V pressfit and just was wondering if there's any special equipment needed to actually install the master link. I saw conflicting information about this on some sites and don't want to ruin a $150 part!

I guess I can take the wheel off, break the bead and reseat and if it's in the same spot of the rim it's rim related, tire it's bead related and needs to be replaced?

A little rubbing with steel wool may be a good idea while it's broke down. A little piece of dirt or corrosion can cause a small leak and may be easily removed with the steel wool.

If you have the stock brakes & you haven't rebuilt them and replaced the lines there will be all sorts of junk in there. By flushing the fluid you've probably also stirred it all up. There is also a pressure release hole that gets blocked in the master cylinder. Check yours is clear.
