Quad QHD-1 brake problem

[insurin]

Noob alert!

brake system is Quad QHD-1 (hydraulic)

I just took the back wheel off to replace my inner tube. When I have put the back wheel back onto the bike, I noticed the brake pads were catching the brake disc slightly. As I am pulling the brake, I can see the pads squeezing the disc brake but they are not releasing it enough for it to freely spin.

I have never had hydraulic brakes before but I am hoping you are just going to tell me that I just need to top the hydraulic fluid up

Try this:

1. Set the bike on it's own wheels. (Important)
2. Loosen the quick release, push down on the saddle and retighten the quick release.

My bet is that'll fix it.
