yeh so theres that cable that connects both callipers together than your brake cable pulls , sorry i dont know the name.

anway, how do i adjust this to make the pads same distance away from the rim?

I adjust it and then when i press the brake the cable that attaches the callipers together just slips more to one side so it makes them uneven again :(

if you can understand please give advice?

that's the straddle cable.

to center the brakes, you need to adjust the spring tension in the arms.
1. loosen the 5mm allen bolts in the middle of the brake so the springs are loose.
2. to put tension in the spring, turn the spring cap using an open-end wrench (whatever size fits for your brake). always pull the wrench toward the FRONT of the bike- right spring tightens anti-clockwise, left cap tightens clockwise. you only need a little bit of tension to make the brake spring back. too much tension will wear out the springs and make the brake inefficient.
3. if the brakes dont pivot smoothly, take the arm off and put some grease on the brake post.
4. put a little bit of tension on one spring, then tighten the allen bolt while maintaining the tension by holding the open-end wrench in place.
5. now go to the other arm and do the same. turn the open-end wrench toward the front of the bike until the tension in that spring matches the tension in the opposite spring and the brake is centered. hold it there and tighten the allen bolt.
6. pull your brake lever a few times to make sure everything is centered. if it's off, make minor adjustments until it's just right.

he might have the springs backwards.. or one side has more tension than the other

Thanks for all this :D

when you say pull towards the front of the bike , do you mean if the bike is on wheels or flipped?

either way, the front of the bike is still the front of the bike. if youre not sure, turn the cap with your fingers. if you can feel the spring getting tighter and the pad pulling away from the rim, you're turning it the right direction. if you can see the spring from the side, you should see the spring contract a little. if the spring bows out when you turn it, you are either turning it the wrong way or you have the wrong spring on that side.

what brake do you own?

because evo 2 needs the distance to be uneaven as it has different sized springs.

good point. it's not so important that the brake pads are equidistant from the rim as that the pads hit the rim at the same time with the same amount of pressure. if the pads are equidistant but hit the rim unevenly, they will not stop as well and will vibrate, creating those horrible goose squawk noises (which some of you seem to like).
