Disc brake issues

[BristolScouse]

Ok guys, I'm new to cycling and have virtually no experience in servicing or looking after my bike. I have a Whyte Charring Cross 2013. I've had it for a couple of months, it's had its 8 week service, just a few tweeks needed. It was washed and cleaned last w/e, no chemicals or anything got onto the discs but when i went to ride it today the thing was creeking and rubbing like a son of a gun. Having had a quick look it feels like the disc is warped but on closer inspection it looks ok. The brake component (Avid BB5 R) has to little levers on it. If I push these up or down the rubbing stops. Also, if i turn the wheel to the right it stops rubbing, but if its facing forward or to the left it squeeks and rubs again. Any help or advice would be greatly appreciated. Thanks

Make sure the rubbing is coming from the brakes. Release the brakes completely. Once this has stopped the noise, bring them is slowly with a ratio of 2/3 (closest on the inside). Hopefully someone who is better at how to describe thing technical will help but in the mean time watch this.

Cool cheers for that I'll have a look. Do you know what the little levels things are?

A brake cable will tighten slightly as you turn the steering and with a cable disc, rubbing can happen if the pads are very close to the disc.

What do you mean by the little levels? Are you talking about the two bright copper tabs, visible in the picture above? They are the locating tabs for the brake backing pads and they should be quite visible and level. Sight carefully parallel to the disc to check that the brake pads are parallel to the disc surface, if they are not, you or the mechanic haven't pushed the pads home fully - try pressing them in until they click.

"What do you mean by the little levels?" that was a typo, meant to be levers. Ive noticed that when you squeeze the brake lever one of the small levers moves inwards towards the wheel
