Shudder when braking on 30s

Postby MikeD » January 15th, 2014, 2:41 pm

Hey everybody,

I recently picked up a set of 30s and love them. I went to the local LBS to adjust my brakes (6700 Ultegra, approx 600 mi on pads) for the wheels.

The issue I'm encountering is a pretty strong shudder or vibration when braking even at moderate speeds. The LBS tech mentioned that with some wheel's angled brake tracks it's just not something that can be dialed out.

Is this an issue that anybody else has encountered? If not is the problem likely my not using new pads? Or could my LBS possibly have just not adjusted the brakes correctly?

Thanks in advance for the help!

-Mike

Mike,

Thanks for writing. I just want to make sure that the wheel is true. Did the bike shop mention anything about the trueness of the wheel? Also, does the brake track look smooth and free from any dents or dings?

Take care,

Hi Chris,

I don't believe the wheel was checked for being true. They looked in good condition with no dents or dings when I put the wheels on. Went for an initial ride and braking power was less than I was accustomed to so that's when I went in and had the shop adjust the brakes.

Should I check if the wheel to see if it's is visibly true, or should I take it in to a shop to have them measure?

You should be able to do a quick check at home on your bike. If you spin the wheel and look at the brake track pass the brake pad, there should be little to no lateral movement of the brake track.

Can you check that? Feel free to call me at 702-529-4744 if you'd like. I can run you through the process.
