I have a 2007 TLS and the brake rotors keep warping. I have replaced them twice and they keep warping. I do the break in procedure that the manufacturer recommends. I am running R1 concepts Geo carbon blank rotors. I do not track my car and don’t brake hard repeatedly.
Any advice on what to do?

 

Are all 4 rotors warping? is it the front two? the rear? just one or two? ...

 

Just the front 2.

 

Are your pads wearing evenly? Maybe brake pistons are sticking and cuasing them to heat up the rotors enough to warp them.

 

Also how does your brake fluid look? when was that last changed?

 

I’ll check pads when I can and the fluid was replaced/bled when I changed the rotors the 1st time.

 

It could be that the pads are too soft and leaving material on the discs causing the warp. What pads are you running?

 

I am running the R1 concepts Optimum OEp pads.

 

The OEP pads are meant for very regular driving, the Brembo brakes on the TL-S are a bit sportier and are probably causing the the pads to warp the rotors. Easy solution, switch to semi-metallics for a little bit to clean your rotors up and then to to a good ceramic pad like akebono or something else from EBC.

 

I have replaced the pads and rotors and the brake fluid looks to be clean
