Stock brakes. How many miles before issues started?

Kzonts

I have a 2015 Sport with just over 13,000 miles. I had to replace the front pads and resurface the rotors. It started to shake during braking. I was a bit surprised at how soon it developed that problem. She's a daily driver and mostly highway miles. I replaced the pads with Hawk brand and now it's smooth as silk.

Anyone else have the same experience?

The shaking that you speak of is more than likely pad buildup on the rotors.
Did you do a bedding process when you changed everything?
Too many times people say that their rotors are "warped" when they are not. These thing are 30lb cast iron on the fronts. Warping would take serious amounts of heat.
Get some brake cleaner and do a bedding in process.

Thanks for your input. Yes, I did the typical bedding process. And you're probably right about the rotors not being warped but I have always resurfaced rotors when I replace the pads.

Kzonts

If this happens again would you recommend just cleaning the rotors and bedding again with the existing pads?

TreeSemdyZee

I would. I've never tried it, but you might be able to sand the rotors to get rid if the buildup.
Can't think of a reason that it wouldn't work. Basically would be a "mini-turning".

I'm hoping the Hawk pads don't do this. At least not for a while. We'll see.

I put on Hawk ceramics in 2012 and have had only minor issues. I put on slotted rotors later.

This is only necessary if you install new pads that are composed of a different compound that the previous pads

As mentioned, the "warped" rotors are almost guaranteed to be just uneven pad deposits. You can have the rotors "turned" by any brake shop to remove the excess pad deposits and level the rotor surface for smoother braking.

From what I can determine, most of these scenarios are caused by improper braking habits, although an emergency maneuver can do it as well. My wife "warped" the rotors on our Z in less than 20K miles when she was daily driving it. When the Z became my DD, I fixed the issue and have since put over 50K miles on it with absolutely no shuddering or shaking under braking.

If you want to try to avoid having them turned at a brake shop, you can try bedding the brakes again. You'll need to get them good and hot to remove the excess pad material. And whatever you do, don't hold the brake pedal down while the brakes are hot and the rotors aren't moving - that's what causes the problem in the first place.

Thanks for all the input folks!

Here is what I use to resurface the rotors so they can be re-bedded. Works like a charm. Best if the rotors are removed but you can use this with the rotors still on the car. You will have to remove the calipers to get to the back surface if you leave them on the car. You should scuff the pad surface too using 80 grit sandpaper if you plan on re-using the old pads.

Rotors don't really "warp" they build up an uneven layer of pad material and this is what causes vibration when braking.
