rear brake lever failure
I just changed my brakes (from sp to dp) then I found that the rear brake lever is not working properly.
Press the lever doesn't move the cable for the first half of the way. But the lever works on the second half of the way.
The calipers seems to work fine, front lever is also ok.
What's going on with the rear brake lever?(I didn't even touch the lever before I noticed the problem and before I took off the old calipers the lever is also working fine.
It's a very old 105 lever.
