Front Rotor Vibration

[GradeABeef]

Since my accident, I have a had a little vibration while using my front brake. The vibration changes with speed so I'm sure its because my front brake rotor is a little warped.

Is there any repair for this or do I just need a new rotor? They are 200 bones on ebay and even then if they are not stored properly they might be warped too. I didn't know if it was possible to turn them, I couldn't imagine anyone with the ability too.

Warped from not storing properly?

If it doesn't always vibrate during braking as you indicated and it is more speed sensitive id bet its wheel and tire balancing issues.

Try giving the disc a good scrub with brake cleaner & steel wool before deciding to replace it. Usually the 'pulsing' sensation is just glaze built up in the rotor.

Great advice go cytocis, I didnt think I might have glazed a portion when I wrecked. Ill do it when I swap pads tomorrow.

If rotors are not stacked on a shelf properly, like too many, or off center or leaned up against a wall etc. they can become warped or untrue.

I figure it has to be the rotor because it's a fast vibration at higher speeds and I feel the vibration slowly decline as the bike comes to a stop. I can feel the spot where it grabs because the bike jerks to a stop. Not bad but enough to feel it. When I release the brake it goes away.
