car shaking when I brake at high speed?

Your brake rotor need to be resurface. Proabably need to change the pads also. Had the same problem when I had my 95 SC400. Changed the brake pads and resurface the rotor at the same time and problem went away.

I noticed that when I hit the brakes at high speeds (anything over 60mph) my steering wheel would shake alot. Something's wrong with my brakes? Should I take it in?

Globe I had that same problem on my GS. I took it in and got my rotors resurfaced and my pads sanded and the problem went away..

however, the problem came AFTER i got my new TRD pads, installed, and had rotors re-surfaced.......??!??
could that be warped? What does warped brakes mean? I don't know much about warped brakes!

Globe,
My mom had a problem with her BM still shaking after the rotors were resurfaced. When we took it back the rotors were not resurfaced right. They redid it and it was fine.

I had the same problem with my previous car. It came out to be what everyone else has suggested to you. My rotors were warped and I had to get them replaced.
I've seen some cross drilled rotors on E-bay for the GS. I don't know how good they are!!! Check them out, but beware, a lot of people have said that they are not what the seller claims--meaning the company that makes them.

I heard that if it wasn't done right it could mess up your pads as well. That is why when it just came time for me to replace my pads I got the TRD ones and TRD slotted rotors from SteveG at the same time.

I have relatively new rotors (less than 6000 miles) and TRD brake pads. My steering wheel also shakes when braking at high speeds. I cant remember if the steering wheel vibrated when I had stock brake pads.
Anyone else with TRD brake pads have this problem?
Can there be another reason for the steering wheel vibrating while braking?

Hey Guys,
Before I did my Supra TT brake upgrade I had the Kazuma brand (TRD brake pads) that I picked up from Steve @ Carson Toyota. I too had the brake rotors warp as well. Initially, I thought the same as everyone here and I still believe it may be because the rotors were not properly resurfaced.
HOWEVER, now that I heard more incidents where the TRD pads have caused rotor warpage I am starting to develop the theory that the TRD pads are too much for stock rotors. Here's my theory - and it's just a theory...
TRD pads have better stopping power than stock pads. This stopping power translates to a higher degree of friction. The more friction, the more it translates into heat. The stock rotors tolerances may not be able to handle the higher heat and thus warping occurs. So, to answer Globe's question, a warped rotor is a rotor that has uneven surfaces on the area where the brake pad applies to. Because the surface is uneven, yet spinning at a high rate, once the pad touches the uneven surface it will cause a vibration that resonates throughout the wheel and translate through to a shimmy or vibrating steering wheel. It will usually occur when brakes are applied at higher speeds and sometimes the vibration can be quite unnerving.
So, my theory is that if anyone plans to buy TRD pads, one should also consider the rotors that TRD sells along with the pads. This makes sense that TRD is now selling them as a package because maybe a few people have already reported that the TRD pads alone are causing the stock rotors to warp - but I am sure nobody will admit that - remember, it's just a theory...
Hope this helps.

If the TRD pads are, like you said, too much for stock rotors to handle, then even if I get the rotors resurfaced again, will they become warped again?!?
What can I do? Go back to stock pads when the TRDs wear out? Or replace the rotors with TRD ones?
Anyone knows the cost of TRD rotors compared to stock rotors? I got TRD pads because Steve sells them for cheaper than what the dealer charges me for stock pads. Will rotors turn out to be like that?
