Are all canti brakes the same for braking power?

I have Avid Shorty 4 brakes on the cross bike. That thing won't stop worth a crap. It is ok most of the time, but on these gravel roads around here these brakes are killing my hands. On a 15% bumpy bumpy descent the hands are already heavily pressing into the hoods and when you squeeze the snot out of these brakes it will kill your hands. I have had to stop in mid descent before just to get my hands working right so I could hold on. Are these typical, good, or bad canti brakes? What would be a good set to get if I need stronger ones? Thanks.

If they are adjusted correctly and not working, swap your pads. You may just need a softer compound. Salmon Kool-Stop pads are supposed to be the hot ticket.

Cool. Should be cheap enough to try out. Thanks!

I've seen multi-compound pads too. No info on them, but look interesting. Some have a rubber squeegee to clean the rim as well, which could help too.

My cantilever brakes and v-brakes stop like disc brakes. I can lock the tires up without squeezing the lever to the grips so yours must need some adjusting or something

First off are you using road controls or MTB? If using MTB levers with cantis then that's a major flaw. However, poor performance compared to any other type of rim brake is typical of cantilever brakes. Try mini-V brakes, they have much better leverage and will work with road pull levers. Can be had for cheap http://www.universalcycles.com/shopping/product_details.php?id=48336&category=34 up to expensive http://www.paulcomp.com/minimoto.html

If you are using MTB brake levers you will need regular V-brakes.

You can also check these brakes out available from Amazon.

I also copied this note from the review someone posted. I thought it was good information if you do swap.

"Addtional items you need to purchase if moving from a standard canti setup:
10mm spacer (to replace the cable hanger in the headset stack)
Jagwire v-brake noodle w/barrel adjuster"

I have a typical cyclocross setup with SRAM Rival shifters. Avid shorty 4 brakes. LBS said Avid Ultimates or Paul's would be better but to try better pads first like Hack suggested. I also need to practice getting in the drops to get better leverage but on these steep gravel road hills with gravel like marbles that is a challenge.

Pad compound and my poor opinion of cantilever brakes aside, that symptom alone points to a lever mismatch, or straddle wire too long (for a low profile canti), or both. Your could shorten the straddle wire and see if that provides improved leverage when the lever is near its limit.

Knowing Mars like I do, I think he's trying to get someone to say "Well, if you really want to be safe, you should get a new bike" so he has some ammo to approach his CFO with.....
