I was in a bike workshop last year when a guy brought in a bike to have the brakes bled. Two pro mechs (both long experienced) took over an hour before giving up.<br /><br />I've done it on motorcycles and cars (including hydraulic clutches) but as you can see from the various syringes and plungers on offer from Avid and the like, bicycles are even harder. Now you can buy new brake "systems" that come in one piece lever/hose/calliper. I suppose the idea is you just check everything instead of bleeding.<br /><br /><br />From science class I remember that all fluids are incompressible. Brake fluids are hygroscopic - they absorb water into solution so that heat "boiling" the fluid does not result in total loss of braking (BT, DT). I don't think this is really an issue in bicycle brakes (heat problems are more with the pad/rotor interface) but DOT brake fluid is pretty aggressive stuff. No doubt mineral oil is more benign and works just as well.<br /><br />Hydraulic brakes are nice, but not *that* nice. And shifting?

With properly designed mechanisms, no such force should be needed to shift gears. It's probably just something that's designed for electronic control, which depends on a functioning battery. And we saw how well that worked in the Tour de France.johnbhttps://www.blogger.com/profile/15624063335422874333noreply@blogger.comtag:blogger.com,1999:blog-8492685525705691186.post-80625727802191559772015-08-29T15:32:30.013-04:002015-08-29T15:32:30.013-04:00Amen, brother.

Like I...You are right - that's definitely true. Like I said, I don't know what kind of fluid this particular system will be recommending. Mineral oil reportedly has a longer shelf life. I'm unfamiliar with disposal recommendations. Boiling points for mineral oil brake fluids seem to vary by maker -- which can be a possible problem for disc brakes if it starts to boil under hard braking. Still messy and a P-I-T-A to replace, bleed, and clean up though.
