Brake rotors

Lickqid · Dec 8, 2005

My brake rotors havea a "wobble" to them, I don't know how to say it. they rub the pads at points, I can hear the rubbing when i'm riding, and it bugs the s**t outta me. SHould I be worried about this at all? Is there any way to fix it on my own?

try bending it back or get a new one.... unless it's waaving like 1/2 inch then it's not bad... you can always pick on up cheap on ebay.

uh. . .tighten the rotors? i mean, i do it every 5 hours or so on the bike. make sure to tighten in a star pattern, for some reason.

The rotors aren't really lose, they are just bent somewhat, just wondering if its normal.

They're warped. You can gently push on the arms of the rotors where it has a wobble to push it back into shape. Incorrectly torqued bolts or incorrect order could also cause the rotor to warp.

I like to use a long allen key or somehting then just find the points on the rotor where it comes closest to the pad and tweak the rotor out by sticking the allen key into the rotor so you dont get your grummy hands on there. If you want to go crazy and you have an extra $100 burning a hole in your pocket you could buy one of these and really get it perfect...

I use a small adjustable wrench to slide over the rotor and tweak as necessary. Make only small, small adjustments.

If you don't feel confident in trying it at home with an adjustable "crescent" wrench, most shops have a cool 3-piece tool set of weird looking forks that fit brake rotors, and when used in pairs or all 3 at a time, they can straighten out some pretty whacked rotors. I've straightened 2 or 3 rotors at the shop with these things that I would have bet didn't have any hope. They're also not that expensive from some tool makers if one is a home mechanic/racer type who frequently dings rotors in rocky situations.

Morningstar drumstix, made by the same guys who make the $100 fancy rotor truing dial thingy.

How much do rotors run?

I'm not sure what anyone means by the adjusting using the wrench, can someone describe in more detail? or send a pic? thanks for all the help though

That's all you need right there. I use a thin cloth between the wrench and the rotor as well, as to not damage the rotors.

Dont think buy new rotors. Galfer makes some cool original wave rotors or the stockers are usually cheaper.

You torque them in a star pattern to make sure that they are torqued down evenly.

anyone have a pic of how to use the wrenches to correct the warping? I just can't picture it

2 hold the rotor in place then the other bends the rotor strait
