Squeak when walking bike
#1
I have a (new) Globe Haul 2 with Mechanical Tektro disks. The front disk touches the pad no matter how the pad is adjusted. At first it was grinding at ride speed. A few adjustments and I got rid of that, but now it squeaks like mad when I'm walking the bike (through the halls at work.)

I cannot see any way to adjust the pad so that it never touches the disk. Surely there is a way to reduce this squeaking. Will it pass after a while?

If a pad is contacting a rotor continuously, it's a bad set-up. You don't need to adjust the pad but, rather the caliper itself. Then adjust the pads.
Before you begin... ensure that the rotor is attached to the hub correctly and that it is tight. Reinstall the wheel ...

Loosen the two bolts that mount the caliper to either the frame/fork or to the adapter if one is used. Loosen these just enough that you can easily move the caliper Left and Right by hand.
Then, with the aid of an assistant or a strong rubber-band, pull the lever tightly and hold as you re-torque the two mounting bolts. Release the lever and visually inspect while listening. A rub indicates a bent rotor (easy fix). In no way should it be a continuous drag.
I am pretty familiar with a few Tektro models if you need more details. Let me know.

Rob sorry for the delay getting back to you. The re torque trick seemed to help and a few weeks of breaking in also. No squeaks at all now.
