Hydraulic disc brakes

[Fallguy]

I have a Giant XTC3 2004 model with Hayes hydraulic disc brakes. I don't know if this is normal or not but the rear brakes are constantly rubbing against the disc which in turn causes resistance on the rear wheel. If anyone has experienced this problem can they let me know. Thanks

Hayes hydraulic disc brakes have a self-adjusting mechanism, but if you do something like press the brake lever when there wasn't a wheel on the bike it messes it up (it starts to "self-adjust" to there being no rotor being between the pads)

To fix it, take the wheel off and jam as many business cards as you can in the brake caliper, to try and force the pistons out and leave a bigger gap for the rotor. Then put the wheel back in and pump the brake lever until the auto-adjuster finishes doing its thing.

It's explained a little better in their user manual, which you can download from their web site www.hayesdiscbrake.com

From one melbournian to another I thank you. I'll give it a go.
