Fantastic breake caliper — pretty much a required upgrade for WideWheel Installation was a tiny bit tricky, but the breaking power of this caliper by far exceeds that of the post-recall original caliper. I strongly recommend that if you live in the hills you upgrade. Thumbs up! Good support Support team was able to help me with all my problems and made everything right.

Get it right: Proper installation and setup are more critical for disc brakes than for cantilevers, because the tolerances are a lot lower and the calipers must be aligned and adjusted just right.
The objective of the game here is to have your calipers nicely aligned on the rotor so it can be dialed in with no rubbing. Once the caliper is mounted, it is easy to adjust brake feel at the lever by tweaking the pad position on the caliper. I think there is more modulation control and smoother braking if the brakes start working about halfway through the travel of the brake lever.
But depending on your rotors and the interface to the hub, there will usually be a little bit of waviness when the wheel is spun. Keep in mind that once you have a rotor perfect, it will only be matched to that particular hub.
Changing rotors to another wheel will require you to repeat the process. If you have all the same hubs, chances are everything will line up, but if not, you might need to space out your rotor position. Check the position of each rotor in relation to the caliper and use the most outboard for the caliper setting.
Then space out the rotors on the other hubs to match. Wheels Manufacturing makes spacer washer kits and Syntace makes very handy universal ISO spacers that will get your rotor position right on.
This is because the pads need to be bedded to the rotors. This is best done on a small downhill. Roll forward and simply reef on the brakes hard for about 10 seconds. This will build up heat, but not too much. Wait a minute to allow the brakes to cool and do it again. Repeat this cycle times and your brakes should be ready for action.
Lighten up: One of the only drawbacks of the BB7 is the weight The new RSL version , available later this fall, solves this issue to a point. Titanium bolt kits are available for the BB7 and Formula makes titainium rotor bolt kits as well.
Just brace yourself for the price. Pad selection: BB7 brakes come stock with steel-backed organic pads, but you can upgrade these to aluminum-backed organic pads or any number of aftermarket pads from Jagwire, Kool Stop and EBS, to name but a few.
This is a whole story by itself, but the general rule is that organic pads are quiet and strong and wear faster while metallic pads are a bit noisier and longer wearing. Ask your local bike shop for its recommendation for local riding conditions. With that, go out and enjoy your BB7 brakes.

Page 2 Rev. You have selected the best mechanical disc brakes your money can buy! This manual contains important information for installing, setting up and adjusting your new brakes. To ensure that your Avid brakes perform properly, we recommend that you have them installed by a qualified bicycle mechanic. To reduce could lead to a severe injury.

A piece of wood or a dowel of the right dimension would be better, and a steel hammer would work fine. Lastly, from all those videos of Shandro, Simmons, Weir, testing out those new Shimano brakes, it looks like they are either on or off anyways, and those guys are undeniably outstanding riders. At this point a worthwhile compromise because I prefer the feel on wet or icy terrain. Simpl, no fuss and they just work.

The Fall of Discs: Trick your Avid BB7 brakes
How to setup the Avid BB7 Common issues There are a couple of common issues with the BB7 that crop up in many of the forums, many of them due to not taking care with the setup of them. One of the most common complaints is of a spongy feel. This is most certainly down to the type of cable and routing being used. At the very least you absolutely MUST use compressionless cable housing, and make sure that you run it full length to the brakes themselves. Do not use sections of cable with interruptions with one exception which I will mention in a moment as you may do for rim brakes. The cable housing must run full length from the brake lever to the brake caliper. Interruptions to the cable routing cause friction where the cable enters a new section of housing, as well as risking dirt and moisture getting into the routing.
