I don't think I'm getting the most outta my Juicy 3's on my commute bike. The other bikes in the stable have all got Elixir R's which are amazing, so it could be that I'm asking too much. I've tried flushing the system and different pads but I don't seem to be able to put the anchors down with any real conviction.
Has anyone experienced similar?
The hubs are super cheap cup'n'ball affairs which have a little lateral play in them, and therefore the disc rotor. Could a small amount of sidewaysness in the rotor effect the braking?
thought please
Never had an issue with the stopping power of the Juicy brake. Elixir has a signifficant improvement over them though.
If you're pulling the lever back to the bar and there's no bite then I'd say that there's either contamination on the rotor, pads or both or there's air in the system or both!

clean them with some very hot water, a little washing up liquid, an old pot brush, and lots more very hot water.
clean your pads by rubbing them on some wood, or paper, or cardboard.
ride down a long hill, repeatedly stopping hard from a good speed.
don't use spray lube.
I've got Juicy 7s and Elixirs....
In terms of stopping power I can't really tell the difference, but the Elixirs are a lot less of a faff.
I'd say there's either rotor/pad contamination or the bleeding needs sorting out.....
What is the problem - does the lever come to the bar before the brakes start working or does the brake lever feel like it should in terms of 'pressure' and travel, but you just doesn't slow down?
If it's the former then it's probably a bleed issue, if it's the latter, then I reckon it's contamination.
Also worth checking caliper alignment as there's scope for mis-alignment in all directions with the Avid mounting system. If your pads aren't hitting the rotor dead square, dead flat, and at the same time as each other then you'll never get the full stopping power from them as your effort will also be going towards flexing the disc out of shape.
The lever doesn't hit the bar by long chalk. I don't think it's contamination as it's been going on since I bought them (off here) and muck would have burnt off by now. I'll try some better pads once these have worn down.
I find genuine Avid pads work best on Juicy's. They certainly last longest. Sounds like the pads were never properly burned in. They need a good 5 or 6 real high speed repetitive stops to give the best performance. Not tried Elixirs though, they sound good.
Can I ask stumpy01...how are they less faff ?
these brakes are on your commuter - think about how much muck and grease and manky road grime has been plastered all over your bike - why would your brakes be any different?
when was the last time you cleaned the discs/pads?
did the previous owner clean the discs/pads? - or did they plaster them with spray lube, and then sell them because they weren't working very well?
follow my instructions above, then come back and tell me it didn't work, and i'll eat humble pie all day long.
i am an idiot and nearly always wrong about everything.
