trike brake noise?

My catrike speed ( 2 weeks new to me) seems to making an unusual noise. When going around a corner, especially to the right but a little to the left, there is a sound coming from the brake, it sounds like the disc or the pads in the caliper are vibrating like they are loose. I checked the allignment of the pads, the bolts holding the disc on, the caliper and the wheel but all seemed fine. Is this sound normal? or does anyone have any ideas, Id appreciate it.
thanks

Out fishing with Annie on his lap, a cigar in one hand and a ginger ale in the other, watching the sunset.

Wheel bearing OK? Loose cone could also cause that.

actually I do have a tiny bit of play on one side, its barely perseptible but it is there. Im new to this type of bearing wheel, how do I tighten the bearing or do I just replace it?

I'm not totally familiar with the Catrike, but they are normally just regular radial ball bearings. It can be that the bearing is toast but more likely it is clearance between the bearing and the axle or the bearing and the hub. Either of those is not a good thing as either the hub or the axle should be replaced. If a bearing has ever seazed on your trike, you will likely see wear on the axle.

Also, if the Catrike bearings are meant to be pressed on, and someone forced them off, they could have damaged the bearing. They are easy to put on properly but they shouldn't be taken apart again until you are ready to replace them. Even then, you have to do it correctly but perssing the outer race into the hub and pressing the inner race onto the axle.

Are you member of the Catrike forum? You should be able to get lots of help there on this matter... or even call Catrike (great customer service from what I hear!).

But back to the question at hand, what kind of brakes are these? I had Avid BB5's on my trike and I could hear the disc *ching* on some corners (quite a distinctive sound). The disc was hitting the housing of the brake caliper. Even with perfectly good bearings, some deflection 3 inches out from the axle can be present.

I've also had the pads come in contact while cornering and sometimes even on the straightaways. The springs of the pads don't always move the pads away from the disc consistently.

I have since installed Avid BB7's. A day an night difference in performance. They stop quieter, are much easier to adjust, and don't have any of the previous noices. They are also metalic pads which don't grab and definitely smooth out the braking action.
