Rotation Squeak *NOT BRAKES* Advice Needed

Hello again R8 experts.

Here is my problem. Bought a 2008 R8 with 15K on it and love the car, but it has had a squeak now for about a month. I understand that brakes on these cars do squeal, and that is what I THOUGHT this was.

Rotational squeak that can now be heard anywhere below 30mph. Loud high pitched squeak, clearly every time one particular part of some piece of machinery comes in contact with something. It has progressively gotten worse.

Replaced both front and rear pads, had them grooved, had them lubed, all of it. Still, wont go away. Today I notice I can shut it up by turning the wheel right 75% of the time, seems worse when turning left. I can shut it up by a certain amount of parking brake application but only briefly. It is louder the longer I drive the car (impossible to hear for the first 10 minutes) indicating a heat sensitivity.

To add, Ive had warped rotors before and I do not notice the usual shaking that one would expect under hard braking at speed to indicate this.

The dealer has no idea, all brakes replaced (even the **** parking brakes on both sides). Literally everything in the braking system has been done.

Help!?!!

Interested too. My 2012 R8 GT does EXACTLY the same thing and just last week I narrowed down when it does it including it doing it more when the wheel is turned one direction vs the other including stopping it by a greater turn to the right. I know mine isn't the brakes either and its metal on metal so will have dealer check the splash shields with the suggestion above the next time I drop off the car.

Interesting, I am wondering if there is a way I can check this?

But, with that said, why would this get worse over time and worse with heat?

I guess it depends on how comfortable you are working on a car. If you have done brake work before, it's super easy to take the splash shields off (you'll have to pull the rotors to get to the screws holding them on), then put it back together and see if it goes away.

That's what I'd do.

Simple test and it would solve your problem.

The issue is, if the noise is gone when the splash shields are off, you might have poor initial braking performance while driving in heavy rain.

This can absolutely get worse with heat as things expand and contract with temp changes.

You've done everything else it sounds like, this would be my next step. I'm certain the dealer will argue with you about trying this so you might need to do it yourself if you're comfortable of find an independent.

Or something is lodged between the rotor and the heat/splash shield. When it gets hot it squeals louder.

Not the splash guards, dealer has no idea. Back to square 1...

So you don't think its a brake issue but have you replaced the brake rotors?

I had very much the same problem and it only went away when the rotors and new pads were installed.

My noise got progressively worse as time went on prior to the change.

It only happened at low speed after about 10 mins when things got warmed up.

Does the noise somewhat disappear when you feather touch the brake pedal after you first hear the squeal on normal braking?

There was definitely no wrapped discs on mine as they tested true straight on the machine when they took them off.

Okay, here it is. Finally fixed.

After replacing the rear parking brake pads on both sides, both rear rotors and pads, and doing about everything else in the book, the verdict is in...

The rear parking brake caliper was the problem. Apparently it wasn't holding its position and was causing it rub against the rotor and that was causing the squeak. After 5 weeks in the shop and lots of new parts, its fixed. Yikes what a nightmare.

Hi, I have the same problem on the rear right rotational squeaky sound too. I have replaced new rotor on both rear, and also both brake pads but big rear brake pads have not changed yet. The sound got louder after 10mins driving, and turn into left will worsen the noise.

How did you fix it? You mentioned was brake caliper's fault? How was it fixed? Please assist. Thank you.

I had a very similar problem with the front left. Only seemed to make the noise when warm. Over a few weeks it got progressively worse. It turned out to be the CV joint. Apparently Audi have come out with a new type of grease and the dealer repacked it and it was fine after that.

Might not be your problem, but worth checking so that you can discount it.

You need to REPLACE the rear parking break caliper.
