I've always used Avid brakes and not for really anymore reason than it's just whats came on most of my bikes. With several mountain bikes in the bike room, to start adding a different brand would just make things a hassle. I've ran pretty much Juicy's for years with no issues, just change the pads and go, never had to bleed them. Then along came the Elixers, I bought a set for Melinda and they worked pretty well for the first couple of years so when I ran across a used set for what I thought was a good deal from a local I went ahead and scooped them up. Right off the bat I had to bleed them just to get them to work. Since I've had them less than 6 months and I'm looking at a 3rd bleed I think it's time to send them to an early grave. Change the pads, bleed the brakes, that pretty much sums up what I do with these brakes.
Since I bought the used ones, Melinda's Elixers have joined in on the bleeding party. It's been ridiculous and I'm seriously considering buying stock in DOT 5.1 brake fluid. The newest Elixers are supposed to have fixed this problem but since they are still new I'm not ready to take that chance.
Not wanting to dump more money into brakes that don't work properly I went ahead and pulled the trigger on not one but two sets of Shimano XT's. I've heard nothing but good reviews about them and I'm not talking about what the local yay-hoos have to say either.
If you're looking for a set of used hydros don't ask me if I'm selling the Elixers, I'm not going to sell them to anyone I know, knowing they're not worth a crap. I found out after I bought them that there was SRAM memo sent out about the bleeding issue but that was a little too late.
