Steering wheel shake?
Quick question for those who know much more about braking/handling systems than me.
Last night I was screwing around with my G-tech trying to work on my launching, 0-60 times, etc, and I noticed after about 30 min of what I would say is moderate braking, I started getting some shaking in the steering wheel during light /moderate braking at like 70-80mph range. Its not physically shaking noticeably, but I could definitely feel it in the wheel, and this is definitely something I haven't felt yet since I bought the car. Any ideas what the possible causes of this are? I've never really gotten on the brakes hard at all, aside from the occasional hard stop to show friends they work :) |

Anything like that? If it is, Modshack has a good explanation on page 2. |

Same problem this morning on the drive to work. Only on light braking from 60+ mph range do I feel the wheel start to vibrate.

Yep, it sounds like the rotors are slightly warped from the braking session.

One of the brake guys should correct me if I'm off, but my immediate thoughts was pad deposits on the rotors. If you got them heated up, then stopped in one place with the brakes on for a bit, or put the parking brake on for a bit, that would do it.
You can get the rotors resurfaced. Any brake shop and even most mechanics can do it. And don't let someone try to make you think you need a whole new set of rotors. If you have abrasive pads (HP+), it's possible you can repeat the bed-in procedure to remove the deposits. If you don't know how to do this, I recommend resurfacing. |
Yup definitely warped rotors

and then after about 15 min or so I parked for awhile after stopping to talk to this guy in a 2010 STI who loved my car. |
I did the same thing. pad deposits... got the rotors turned works just fine now

The good thing is that it's a relatively cheap fix... |
Don't immediately assume it's warped rotors, as others have said, may very well be pad deposits, and most likely it is........ unless you did something wacky like ran through cold standing water with very hot rotors.
|
Either way, the solution is to have the rotors turned.

You mean Brake Judder
The technical term for what you are experiencing is "brake judder." And "brake judder" is caused by an uneven layer of pad deposits on the rotor.
If your rotors were truly warped then you would experience the vibration all the time. They would vibrate when cold and when hot. I was able to cure a brake judder problem on my Z with 3M Roloc Discs attached to a drill. I used one disc for each surface and gave my rotors a good scrub. Voila! Problem solved. |

This is why bedding procedures should never dictate a full stop. It's usually 35 down to 15 several times, then 55 down to 25 several more times, etc. Once they are hot, you can feel the green fade starting and you can smell the pads. Drive at least a mile without using the brakes to "freeze" the transfer layer in place. Chris |
