I read a thread about this before on here and cannot seem to find it anywhere. Here's my problem...For one my car pulls to the left, so I'm assuming the alignment is off. But at higher speeds when I press the brakes I get a very violent vibration coming from the front end f the car. It shakes hard until you slow down to a certain point. I read on here that somebody else was having this same problem with their car and they upgraded their brakes (rotors, pads, maybe even calipers) and they still had the bad vibrtation. Somebody else said that it was the alignment on the car.

My car is an '01 SS and only has 31k miles on it. I'm kinda lost and I dunno if I should change out the brakes and hope that that fixes it...or if I should aim for getting the alignment done and that fixing it. Can anybody help?

warped rotor mine did the same thing

Is that all? That's odd, well kinda...it just seems like it would be so much more. I thought it could be something with the brakes but I didn't want to just jump into upgrading the brakes if that wasn't the problem. Thanks man...anybody else have a clue?

From what you describe it sounds like brake disc warpage.

Alright...well that would have been my first thought until I read where some guy experianced the same thing and he replaced his brakes and it didn't go away...I just wanted to make sure I'm covering all the basics...thanks guys.

Yup what these guys said. I feel your pain

I need a MAJOR brake overhaul, and soon.

You'll usually feel a pulsing in the pedal from a warped rotor. Warped rotors are common on the 4th gen cars and the LS1 factory (actually 98 and up brakes, V6 and V8) rotors are known to warp. If it's not the rotors, it could be a bad tire or bent wheel.

Variation in transfer layer thickness on the rotor. Many people call this a "warped" rotor.

Change your rotors, you'll be amazed!

Well it sounds like a warped rotor then...I'll change them tomorrow. Thanks guys!

You may as well upgrade when you do it. go to some aftermarket so it doesnt happen again . maybe some drilled and slotted rotors

VIP1

That is not an upgrade.
Stick with blank rotors.

warped wheel or rotor. If its a wheel you could try finding which one is warped and rotate it to the back and see if its helps

Well regardless if drilled and slotted are more effective or not, hit up the WS6store. Their prices are UNBEATABLE! Much cheaper than stock rotors for all 4 and look better.

And deal with reduced stopping effectiveness, and possible 'brake pad cheese grater' effects chewing up pads like there's no tomorrow. And eventual cracking too.

Strano has a great deal on a set of blanks. Go there and get those instead. Not only are they inexpensive, they are actually thicker/heavier than the stock rotors, so they won't warp, and will withstand the heat better - and not chew up pads or crack, all while giving maximal braking.

The dude has only 31K on the car and doesnt know the difference between an alignment issue and warped rotors.....I doublt seriously that he is Auto-Xing it or driving it hard enough to see any adverse effects from "sub par" rotors! For daily driving the WS6store drilled/slotted rotors should be perfectly fine. Afterall, if the design concept was good for nothing but destroying pads I dont think that drilled/slotted rotors would be found on factory vehicles(think WRX).

Its on there for bling factor and the manufacturers admit it.

Well I still haven't changed the rotors due to money issues...but usually when you have a warped rotor you'll feel a pulsating in the brake pedal...but that's just it, I don't. Only in the steering wheel. And it's not always constant...just at certain higher speeds.

VIP1

Where you feel the vibration depends on which rotors are warped. Warped front rotors will cause a left-to-right vibration/tugging in the steering wheel.

Mine pulses real bad through the pedal but doesn't do what is described here. Does that mean my rears are probably the bad ones?

Not that it matters, i'll replace all 4 anyway.

HPP

Mine is the same way (I have the Strano blanks and PBR pads at home, wating for time to get the install done), sometimes there is no shaking, sometimes it's real bad. Usually worse at higher speeds.

When I talked to someone at Strano, the first thing they asked was if I felt pulsating in the pedal. And to be honest, I never did. Later, I started paying more attention, and at higher speeds, under hard braking, I do actually feel pulsating. It could be from the back, or it could be a case of simply needing to clamp the calipers tightly enough to get the pulse felt through my shoes - or it could be that I'm just not very sensitive to it.

In any event, what you're experiencing must be related to the braking system, if it only occurs when braking. And since the stock rotors are known to warp, and since people who have had warped rotors feel this very effect..... it's likely that's what's going on, whether you feel pulsing or not.

Just remember to get a set of new pads to go with the rotors, bleed the system thoroughly, and follow proper bed in procedure after the install is complete.
