Car shaking when braking at high speeds?

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.

You are spot on.. When it was taken to the shop (on a tow truck)...I had them check the car for any suspension issues (in addition to the obvious wheel replacements), they said everything checked out fine, just needed an alignment. It all felt fine during the following 2 months.

So it's been checked up & down twice now., after the initial incident 3 months ago & again today.

Ins deductible would've been/is $500.
The rotors/pads now needing replacement due to the shaking when braking $250.

I am betting on the rotors being warped, and betting it is caused by your driving style. Hard braking puts tremendous heat into the rotors, and after they are turned once, there is less metal to dissipate the heat, and they will warp easier the next time. When we lived in the mountains of north GA, tires and brakes lasted about 6 months before you put new rubber and changed / replaced the rotors. To cut down on repair time, I kept an extra set always ready to go.

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

Guess I should have read the whole thread before I made my last post. Your last car was about 500 lbs less than your Camaro, and not near as powerful, so most likely you are stopping a heavier car from a faster speed than in the past, thus brake damage with your current driving style.

That may have something to do with it. Wheel bearings perhaps. All we on the forum can do is guess.

As for the lighter, less powerful car; that car had disposable rotors and smaller brake pads. The SS will out stop it. In a heartbeat.


One good thing to do with the Brembos is to smack the shit out of them every so often.
I mentioned that earlier.

I know it will out stop it, but the point is that heat is going to be high if done consistently and it has to go somewhere. The rotor can only take so much. That is my point.

At about 15-20mph...The 1st spin was on the road, the 2nd spin is when it slammed into the curb & onto the grass, 3rd spin brought me back to the road. (It felt like slow motion)

Upon 1st inspection at the shop they said that all checked out, just needed alignment.

3 months later (yesterday) brought it back about to the 'shaking when braking', they said I need new front rotors & pads.

Anyhow while "we are all guessing on the forum", the "pros" at GM checked it out twice now.. Hoping this settles the "warped rotors at only 16k miles" issue.

Parts are on order, once this gets replaced I'll definitely try your advice about the hard stops once I while. Thanks

Update:

After getting the new rotors/pads up front, I left the dealership & noticed the hard shaking at high speeds was fixed! But.....Still felt a slight wiggle when breaking at low speeds... Same as what I felt before at low speeds.

So now 2 months/5k miles later I'm wondering if the hard shakes are coming back :(

On my next oil change going to tell them to look at it, again.. 20k miles & not thrilled about the brakes on this car. The saga continues...

Definitely do not settle! Have them replace the entire front end if they have to.

Hope they find the culprit/s, good luck getting this fixed.

warped rotors. Stay away from those cheap ebay slotted drilled junk.

I been there, just changed the fronts and all shaking gone ... oem GM rotors are quality.

Well none of it is warranty, they have already made me pay for the pads & they told me the rotors were only covered as a 1 time courtesy.. So anything at this point is all out of pocket, they call it reg wear/tear.

Funny, I drive my Camaro 3 miles to work and back every day and really not much more. Mine started shaking the other day and was only doing 50. I have hawks HPS brakes all around, so I will keep an eye on this one...

[Adrian97c]

Brought it back in, again.. They resurfaced my rear rotors, $147... Still pulsating... So now they wanna try the front rotors again lol so I'm supposed to replace rotors every 3 months?? Wtf is wrong with this Camaro?!

Thinking of trading it in for a Lexus RC F, ugh :(

Turning the rotors is never a fix for warped rotors. They will always go back to being warped. The main causes of them warping is heat and sudden change from hot to cold, and or improper torquing of the wheels.
