Hi everybody!!
A few days ago I noticed the rear brake cable on my girlfriend's old bike was loose around the top tube area. The brake worked fine, although they had a bit too much run.
I thought I could simply tigthen the cable either via the barrel adjuster or by readjusting the clamping position on the caliper.
Well, I did that, and the cable around the top tube was much tighter. Only problem is, after braking, the calipers would adhere to the wheel and not return to the original position. At this point, the cable would be loose.
I thought it was a problem with the pads sticking to the rims, so i cleaned everything, even changed the pad, but no result.
Basically, if the wire tension is too high, the calipers fail to return to their original postion. Is this a problem with caiper lubrication?
Oh, I forgot to mention the brakes are dual pivot calipers
Thanks!!
