Before I throw them in the rubbish. I have never been able to get these things to work properly. These are a few years old and probably have about 60 uses or so on them. The pads have about 20 rides on them or so.
They are on my FQ. No matter how I bleed them or adjust them, they drag on the disk (6" wavy rotors Hayes)
Here's what I did. I put a business card on the rotor, took off the caliper, pressed in the pistons, put the caliper back over the card on the rotor. I took the brake lever and rotated it toward the sky. Took out the screw on the brake lever resivour and put in the plastic piece in the hole then a tube into the plastic piece and put the tube into brake fluid. I open the bleed screw on the caliper and push new fluid through the system with a shringe with a hose on it.
I push the fluid through the system till I don't see any bubbles coming out of the tube (I squeeze the lever a couple times too) at the handle then crank the bleed on the caliper shut after I release the handle. I then put the screw back into the resivour on the handle, reposition the handle and squeeze a couple times. I then hold the handle and tighten the caliper mounts.
I then take the business card out and test it out. It works fine for a minute, but after squeezing the brake a couple times the pads are dragging on the rotor again . Any ideas?
