Ahhhhhh. Thanks for the patience. Order canceled. Will look into the E-brake condition shortly. Hopefully on a warm day. I hadn't heard of this issue so will admit I am ignorant. so thanks again.

No worries. Like I said, I'm not *entirely* sure if that issue translates over to the 12th generation that you have or not, but it's worth the check, and canceling the super fancy rotor order wasn't a bad idea.

BEASTY

Ahhhhh. Thank you for the tips and patience. I was blissfully ignorant of this problem. Having just moved to the northeast (which is where my truck has been its whole life) from Texas...this whole rusting out stuff is a new wrinkle for me. I will check the e-brake out soon and let ya know. Thanks again. (order canceled)

I've likely bought my last set of drilled and or slotted rotors. Go out and try to get any of the multiple places around here to turn them. No dice. It can be done. Most places have no interest at all to turn them, don't know how, couldn't care less about even entertaining the idea.

With the vibration, start with a balance. With you getting new wheels and tires you should have a fresh verified balance to see if that makes any differences. After that would be evaluating driveshaft run out, yoke phasing if applicable, and u-joint operating angles.

yeah. What I have been told is that rotors are cheap enough that its usually easier to buy new ones. And you will be hard pressed to find someone to machine drilled/slotted rotors because they would have an interrupted cut, meaning as the insert or cutter face goes across the rotor each time it encounters a slot or hole and "hits" the other side of said slot/hole there's a near 100% chance of that tool breaking or chipping...ruining the job. I work in manufacturing and specifically machining and that always the case.


Thanks for the check list. I'm 85% certain its the tires as at slow speeds (0-25mph) you can feel the uneven ridges of the tires. I have had it on asphalt and glass smooth concrete and felt the exact same.

I'm looking into a front end vibration during braking (but only at speeds around 45 mph, +/- 10 mph). I have an 05 KR, and it seems it may be a parking brake issue as detailed in TSB 08-11-1 (attached). Being that BEASTY has an '09, I don't think this TSB will affect him, but is a good starting point to quickly and cheaply rule out the parking brake.

Have you had your tires Road Force Balanced? Good way to verify the tires are/are not the culprit.
