Used bb7's for 11 years on and off on two bikes. Work well if time spent setting them up. Apart from cable lubing (cable oilers are a great addition) and occasional pad adjustment, need little maintenance. Performance per pound superb!

second the shimano M495
easy to set up, pads always return so no binding issues and as powerful as you need for dalby/stainburn type riding.on one were doing them for under 20 quid, but sold out...
more maintainence (adjust the non moving pad) but apart from that, the only difference is feel compared to a cheap hydro.

the piston mechanism and pad adjustment can cause problems because the parts tend to corrode too easily
I presume it's the salt they don't like as mine are on a third winter of off road commuting, are never cleaned and are fine.

PTFE tubing from Airlines-Pneumatic
BTW try spraying silicon polish on the inside of the BB7 calliper for use on salty roads. Remove pads first

Had a BB7 for a while now. Never had any issues with power, even when I was 18 stone they had more than enough. The only problem with them is that they are a bit on/off, at least with shimano v-brake levers. I reckon people having problems with them either have glazed pads/disc or are using the discs that come with them as I've heard bad things about that disc. I've been using mine with a G2 cleansweep thing and it's fine.

I have used a set of BB7s for a couple of years, the other bike has Hope mono minis. I run Avid flak jacket cables and XTRM950 combo shifters/brake levers. Power is excellent, there is no rubbing, the only issues I have had have been vibration and the fact they seem to need a dead true disc to be happy. With a 160 front they feel much more powerful than the mono mini with a 180, but the Hopes have better modulation and a smoother lever action.
In many countries BB7 are used on high end bikes - especially in the heat where fluid can expand. In the UK journos seem to hate them.

lever action very smooth with the ultimate levers and gore rideon cables for me.

ok,
the bb7s are awesome. I cycle toured across iceland for 2 mths with them - superb...
i use hydros / bb7s and the ease of bb7 in severe applications - ie heat resistance / trail side repair outweighs the slight weight issues
try them and learn to fettle them is the key
