best way to better brakes?(6 posts)

best way to better brakes?collinsc

Who makes the best (fastest stopping) brake pads? Who's rim design slows the fastest? Are there any differences in brake caliber design to make one work better than another?

oh, and, how often you do like to replace your brake pads?

(where the hell are my road bike discs brakes?)

Road bike disc brakes.

They are out now. Avid makes a set of road bike disc brakes that will work with your STI levers or Ergo levers.

Getting a bike and fork with disc brake tabs is another problem though.

I'd love to have one with the Avid discs though as I have a set on my mountain bike and love them lots and lots.

Road braking differs from mountain bike braking rather significantly, and this difference makes for different design needs in a brake. The fastest braking will occur at the point just a fraction short of locking up the wheels. Just about any road brake can get you to the point of locking up the wheels in a hurry; so they can also get you to the point just before locking up the wheels in a hurry. Road disc brakes would have limited application, because they would be so powerful that you would frequently be locking up the wheels- something that would usually be sub-optimal.

The ideal brake gives good modulation- the ability to have a lot of difference between feathering and full-stop. As far as I know, the best brake ever produced is the Dura-Ace 7400. The 7700 weighs less, but lost some stopping power in the process. The 7400 is still in use by most Shimano sponsored pros, and is coveted by everybody who ever used them.
will those 7400 match well with campy levers? nmcolker

And to correct myself, before somebody else does, I believe the correct model number is 7410. The difference being that the 7400 was a single pivot design that went with the earlier 8speed Dura-Ace STI, and the 7410 is the later dual-pivot design.

When I put them on a Record bike though, I do feel a little foolish being able to release the brakes from the levers or the caliper.
Avid makes them now, and they are great...miposy

You can get Avid Disks for your road bike levers now, but will have to have wheels built, have a frame made, and maybe a fork (there is a small selection of cross/road forks available for disks).

I have ridden a cross bike with them, and they are amazing. The weight difference, including the wheels, is about a pound.
