Car shaking when braking at high speeds?

[Adrian97c]

Thx for your response SpeedyG,

I'm going to reply to a few good points/questions you mentioned:

1. I have noticed today that the vibration does occur at slower speeds, but it's more like a slight wiggle as I approach a stop. (Although braking at higher speeds its more noticeable)

2. A 4 wheel alignment was recently performed, but I noticed its now pulling to the right slightly.

3. I tried the emergency brake & still felt vibration.

So according to your thoughts its sounds like either right (impact side) rotor(s), and maybe bearings (like what slingshot needed)?

Lastly you suggested if rotors are fine, then culprit could be rear axle geometry.. I'm not mechanically savy, so dumb question alert: how would they go about fixing rear axle geo? Another alinement? Or (my biggest worry) part replacement? Lol Thx

I wanna approach the stealership sounding like I've done my research & sorta kno what I'm talking about.

That said, I would push for an upgrade to some nice vented rotors and pads.

Unless you are spending BIG $$$ for "real" vented rotors (such as Brembo etc) do not do it as most(99%) are just for show. The holes actually weaken the rotors and will crack/fail much easier. Turn them, or buy new oem's and be done with it.....

Sounds to me like the incident caused more damage than originally thought. If the tire and wheel warranty covered the entire repair, than chances are that's all they fixed.

It is very possible that everything looked okay at initial inspection, but as rotations went on, something is coming to the surface. Suspensions are a finely tuned balancing act, and it doesn't take much to cause what you're experiencing.

Personally, I would take it back to the shop that did the wheel/tire/alignment and have them look at it again. They, as well as you, should have records of the initial repair, and should suffice to file a claim with your insurance company for any repair not covered under w/t warranty.

MrChris,

Good point on showing paperwork to INS, but I'm hoping it's a cheap fix like rotors, etc. which might get covered for free by dealership (small chance). Otherwise if cost to fix is under $500 (Ins deductible), then I'll just have to eat it.

Update:

Brought it in today! (They first suggested new front tires, until I reminded them I just got one replaced lol)

They said the alignment was fine.

Lastly, to stop the rattle they said I need 2 new front rotors & new pads... But it's considered "wear & tear", so "Manufacturer Warranty" won't cover it.
So $130 for each rotor & $250 for both pads = $500+

I guess the days of $40 rotors are over for me now that I own a "muscle car" lol

Anyhow I then brought up how my previous new car I drove (hard for 3 years 60k miles), never needed new rotors/pads (2011 Kia Optima Turbo), & I told him to talk to his manager about my concern with camaro only having 15k miles...

He came back & said they will cover parts & labor for the rotors & the labor for pads, (as a 1 time courtesy), I'll just need to pay for the parts for pads..

So $250+tax is what I'm going to spend.

Generally good idea to change pads along with when replacing warped rotors? That was their suggestion. Vs just replacing rotors

What are your guys thoughts on this? I feel ok with them picking up half the bill. But love hearing other people's views (hence the whole point of forums) lol

I'd be screaming out loud at any suggestion that it is "wear and tear" and my warranty does not cover this at 15K miles.

I actually had similar brake problems on my 1993 Ford Probe. After a few visits to the dealer where the problem was not resolved I told them that next time I'd send my wife in with the car and they will wish they had resolved the problem with me.

They fixed it that time.

[Adrian97c]

@tomlink Lol ya the wife card, nice!

Technically this issue started shortly after I spun out control (3 full 360 degree turns )& crashed into a curb, blowing passenger side tires & 2 broken rims...(& my pride)The wheels & tires were replaced (wheel-warranty covered them), but no other issues were discovered at that time, during the following 2 months is when the shaking while braking began to surface.

Cool info

The last Camaro I had I used to wash it on the way home on a daily basis because where I parked was so dusty and at 45,000 miles the brakes looked and felt brand new. I swear the V6 has the best lasting brakes I ever seen on any vehicle! Plus no brake dust even during a time I went two weeks without washing it!

If not, this post appears to confirm the V6 brakes are marginal and under engineered for the speed capabilities of the car. GM should have installed V8 brakes on the V6 cars.

No, the V6 brakes are very good brakes! Best lasting brakes with the least amount of maintenance of any vehicle I ever owned! I even like them better than the Brembos on the SS!

I never had this problem with my 2011 Kia Optima, but with my 2006 Pontiac G6 I had the rotors cut every 6 months!

I drive like a grandpa & brake slowly/gradually.

So has anyone else dealt with this at only 15k miles??

My SS just broke 15,000 miles and the brakes are perfectly smooth! And to add, on my 2004 SVT Lightning I didn't even turn the rotors when I put new pads on it and at 87,000 miles they're also perfectly smooth. I do drive fast but I tend to not keep constant pressure on the brake when slowing (apply brake, left off, apply brake). Well one time I took my uncle for a test drive in the Lightning and actually had the front brakes smoking! lol....

Common sence says to not spray water directly or otherwise to the rotors when washing the car , if you have used the breaks somewhat intensively
If the rotors are hot , and you hit it with cold water they most luckily will warp , it can even happen if you drive into standing water while the rotors are hot

But my wheel & tire warranty covered the repairs, my actual auto INS had/has no idea of my spin out incident. Wonder if they would now (3 months later), cover any expenses due to shaking. Anyhow my ins has a $500 deductable, so hoping this cost a lot less then that lol

Okay, not to be a "fun sponge", but did you ever do 3x360 in the Kia and hit a curb? And I really wouldn't call that driving like a "grandpa".

Okay that said, do you think it mught be entirely possible that if you were moving fast enough to spin a 3,900 lb car 3 times, that all that velocity and mass hitting a curb, just might damage a little more stuff than the wheels and tires? I'd say it's time to call your insurance agent, pony up the deductible and have what really needs to be looked at looked at.

Not trying to be jerk here, but there is just no way you hit a curb that hard and didn't do more damage to the suspension, just no way. Sorry, has to be said.

What happens in a sudden downpour?
