The Bike Shop / U brake jams up / does not spring back
« on: May 29, 2019, 02:50:59 PM »
Hello guys!
So I bought an used cheap bike for my wife (Mirra Blend) and the seatstay u-brake does not spring back after being pulled hard. The springs are well adjusted and in correct orientation. Cable tension releases too. Brake arms are not touching each other. Tried the stock Tekro brake as well as a AD-990, almost no difference. It seems too me, that the arms jam up on the mounts. I have no idea how that can happen and I've never seen that in over 20 years of BMX.
Any advice?
