I recently installed TRP 8.4 linear pull brakes on my cyclocross bike. They are a vast improvement over the conventional (old-fashioned) cantilevers they replaced.
There is only one little issue that's threatening to drive me crazy: The uneven actuation of the brake arms.
Here's what's going on: When I squeeze the brake lever, the arm with the noodle moves to the rim first, THEN the other arm moves. I've experimented with the spring tension extensively and I've also disassembled the pivot sleeves and lubed them with some Rock-n-Roll Super Slick. Nothing seems to make any difference. (New cables and housing were installed at the same time as the brakes.)
The bottom line is that the braking performance seems unaffected (I can lock up the wheels with just one finger on the brake lever!) and so I suppose that the uneven actuation of the arms is a cosmetic issue. But it still bugs me, especially since I have a few other bikes with various brands of linear pull brakes and none of them exhibit this behavior (both brake arms actuate evenly with a pull on the brake lever).
Has anyone else seen this? Do you have a"fix"? Or should I just relax?
Thanks for reading.
