Braking at highway speeds
I have a 99 Z28 and whenever i am braking at speeds above 60 my brakes feel very unsafe. It takes longer to slow down than i think it should. Also my steering wheel starts to shake while braking until i let off the brakes. At speeds below 60 though they are great. I don't think my rotors are warped and my pads have ok life left. What gives?

Sounds a little strange. I'll give you my 10 cents. First of all, if your rotors are warped, your brakes will shimy all the time when applied. Secondly, if your wheels are out of balance, you will feel the steering to shimy at a certaing given speed and you may feel this through your brakes as well. However, if you apply your brakes and your steering wants to steer into another direction, you best stop driving that thing and have your front hub assembly checked immediately. You could have a bearing going out and at highway speeds this could be fatal to not only your car, but you as well.

Your rotors are warped.
Mine did the exact same thing. Scared me from 100MPH.
Had the rotors turned and put new pads on. Problem solved.2008 Trailblazer SS

Thanks for the input - What kind of pads are you using and do you like them?
Sorry this is probably dumb but - what is having your rotors turned? Do you flip them to the other side or...Last edited by 99blueZ; 04-22-2006 at 09:21 PM.

Stockers.
Girlfriend works for a GM dealership...so they are at cost.
They only have about 750 miles on them and they are feeling pretty good. It did take a little while for them to set though. They almost felt a little slick at first.
I think they were just warped a little bit. When under more extreme braking conditions it showed up, otherwise it felt okay.

They get machined so they are completely even again.

$8 a rotor.
She was great. I needed SO many little parts when I did my swap. Helped out big time.

It's really common for f-body rotors to warp. It can be machined out usually,if it comes back just replace them. Before you remove the wheels though,as suggested, check for play in the front -end. With the car jacked up,try shaking the wheel at 12 and 6,and at 3 and 9 o'clock positions. If you don't feel anything there,remove wheel,and look at the rotors. You can sometimes see the uneven coloration in the rotor from the warp. Have them checked for thickness and compare that reading to the specs before "turning" (machining) them.
