Wyatt Earp Posted August 11, 2014 Posted August 11, 2014 Do it yourself, easy peasy. Go to Tool-up cycles or any shop and ask them to lend you a "bleed block" and buy some Shimano mineral oil. Get 2x 10cc plastic syringes from a pharmacy and a meter of fishtank tubing. Then do as in the video below: https://www.youtube.com/watch?v=QciJbZf6Bqc The good old syringe method, yes it works till the bleeder pushes the seals beyond the pistons.That's why Shimano went this way (the video couldn't explain it better) : http://media.cdn.mountainbikesdirect.com.au/media/catalog/product/cache/1/thumbnail/9df78eab33525d08d6e5fb8d27136e95/s/h/shimano-m575-bleed-funnel.jpg
Wyatt Earp Posted August 11, 2014 Posted August 11, 2014 Dont think you doin it wrong its just that it is a ghetto bleed...I do it myself too....BUT there are some membranes in the caliper internals...squeezing too hard on the syringe if you are in a hurry will pop these membranes and then the whole thing is fubar... The pressure I am referring to will be from your thumb on the syringe plunger....a sign that you have cocked up your brakes is that after a bleed and ride there will be oil leaking from you caliper...Gooi weg Correct.Everything is easy peasy, is it always correct ?Now that is the question.

I usually thread one syringe into the lever bleed port (instead of the funnel) and then connect the other syringe to a length of fishtank tubing connected to the caliper bleep nipple to act like a reservoir for the oil leaving the system (I attach it open-end up to a vertical tube such as my work stand. This makes it easy to recover the oil to re-use in a future bleed.)

divernick Posted August 11, 2014 Posted August 11, 2014 No, but I guarantee you someone will do it. You're not wrong! That said, I love how easy Shimano (and Tektro) brakes are to bleed. All the American videos and documentation say to clean up with rubbing/isopropyl alcohol. What do you use Wyatt? I use windowlene......works like a charm.
NotSoBigBen Posted August 11, 2014 Posted August 11, 2014 I have been castigated by the old Oom a few times for being lazy in this regard but there are 2 things I have not bothered to learn how to do and just pass on to my LBS as they have the expertise and the right tools. Fork services and brake bleeding, purely based on how rarely I actually need them to be done and the fact that it really doesn't cost that much. I reckon I have not had brakes bled more than 5 or 6 times in all my years of riding and 1 or 2 of those were to shorten or lengthen hoses ....
porqui Posted August 11, 2014 Posted August 11, 2014 You could of course just remove the lever pistons and calipers (gooi hulle weg) and replace with Avid ElixirsKeep the rotors. (you did not think that someone was NOT going to post this) Remember Avids ARE servicable unlike some other makes.

Life's too short to sukkel with avids...there is consensus wrt to this.

The purple stuff, but no through bread first.
droo Posted August 11, 2014 Posted August 11, 2014 You drive an alfa don't you? Life's too short to sukkel with avids...there is consensus wrt to this. Consensus in 2 camps, one pro and one anti. Not sure of that counts as consensus though, more like an open war The purple stuff, but no through bread first. IPA tastes far better with Coke though... even if you've filtered the purple stuff...
kolaval Posted August 27, 2014 Author Posted August 27, 2014 Right, eventually took the bike to epic sports (nice guys there!).It seems my brake is leaking, and they suspect its at the O ring. Is this something you fix or replace?If you need to replace is there a newer model brake that will fit?

kolaval Posted August 27, 2014 Author Posted August 27, 2014 Unable to tell if that was a joke or not?My whole 6 posts should give you an idea of my cycling knowledge
Wannabe Posted August 27, 2014 Posted August 27, 2014 Unable to tell if that was a joke or not?My whole 6 posts should give you an idea of my cycling knowledge Sorry, JOKE. referring to the hot debate about which is best, Shimano (what you use for fishing ) or Sram / Avid.
