Saap yaal! I'm a newbie ... I was wondering what would u do or advice for this.....my disc brakes seems to b slightly bent fr n rear causing a friction as I pedal forward I tried bending them as much as I could n make clearance on both sides of the pad but I seem to hit a wall its still rubbing n won't spin freely mostly back n some fr.......should I just keep trying to realign n adjust them or does a bike shop have a special machine for that?

get one of these

keep your wheel and disk on the bike... work your way around the disk bending it back in to proper shape... be patient it takes time.

Yup, what he said.

The problem is that your rotors arent bent, they have experienced dimensional defects caused from an uneven heating amd cooling of the steel. Basically this means it is going to be nearly impossible to get it perfectly straight again without heating it and special equipment so don't feel to bad about it; nearly every rotor on every bike will suffer from this to some degree at some time.

Well by all means you should attempt to straigten it as much as possible with a wrench, just dont expect it to be perfect. Should be able to get it to a usable state though.
