radius brakes on my fuji touring(5 posts)

radius brakes on my fuji touringgildomilo
Jul 18, 2003 6:21 AM
Hi all,
Yesterday on my ride I noticed that my brakes don't have much stopping power. They are some cheap brand"Radius" that look like a knock off of an old style. I've never ridden a road bike before, except for on test rides. Should the braking be extremely responsive like it is on an MTB? if I squeeze with all my might should I be able to lock the tire up? I think the brakes are flexing under the pressure. I'm going to take it to my LBS next week to have stuff re-adjusted and see what they say about the brakes.
Thanks,
Gil
Are rims and brake pads clean?Continental

You should be able to lock up your wheels with a good hard squeeze on the levers. It shouldn't take all of your strength. These brake should stop a fully loaded touring bike descending a mountain. Is there any lubricant, wax, or dirt on your rims or pads?

Seeing as the bike is brand new, I assumed there wasn't. I will have to take some rubbing alcohol and clean the rims/pads tonight. Is that ok to use?? The owner of the local LBS http://www.bicycleclassics.com/ said that some of the brake arms were defective and didn't provide proper stopping power. They seemed like they worked when I took the bike on a test ride. I'll clean them up and see what happens. It seems like the arms don't apply enough pressure to the rim.
Thanks for the advice.

Read this....(especially the part about wide profile cantilevers)

Beyond making sure the pads and rims are clean and properly aligned the usual fix is a longer straddle cable or possibly a wider hanger. Here is an example of proper setup on a similar design brake by Paul Components.

...most users who've posted on the cyclocross board seem to be happy with the brakes once they've replaced the pads and dialed-in the straddle cable/hanger setup. The consensus seems to be that the salmon Kool Stop pads are the best.
