Brake disc thickness question

[Dann]

I just replaced my OEM discs on my 07 R1200RT with Brembo Oro Series discs

The minimum thickness for the rear disc is 4.5mm . Same as the OEM disc.

The minimum thickness of the Brembo for the front disc is 4.5mm (Stamped on the disc) while the OEM minimum was 4.0mm

Why are they different?

Are you sure that is 'minimum' thickness stamped on the Brembo disc? What is the Brembo thickness now? My manual shows the OEM at 4.5mm as new with a 4.0mm wear limit.

 

If the Brembo start out thicker then they might have a thicker minimum wear limit.

 

For best answer try calling Brembo.

I looked on a website that sells the Brembo Serie Oro discs for the BMW and it states that Brembo makes these discs 5.0 mm thick versus the OEM 4.0 or 4.5. he website is https://www.bikehps.com/acatalog/Brembo_Brake_Discs_for_BMW_Motorcycles.html.

The Brembo disc is thicker than the OEM. (5mm)

Why is it that the wear limit is still .5mm?

I thought the wear limit was basically determined by how far the pistons could go out.

There is no info for customers on how to contact Brembo on their web site

After eMailing the Canadian distributor, I got the following answer:

While the amount of wear allowed maybe the same, the amount of wear accrued is typically slower with a thicker rotor.  The thicker the rotor the better is it to hold up to the heat.  Rotor life is always hard to predict due to the variables of the rider style, brake pad and bike.  Safe riding,

For my '06 RT I am doing a brake fluid flush and just checking my rotors.  The CD manual I have says 4.0mm for the front and 4.5mm for the rear is the minimum (4.5mm and 5.0mm new thickness.  I'm showing about 4.2- 4.3 on the fronts, and 4.7-4.9mm on the rear so looks ok.  58,000 Km, since new, and I'm not a squid rider so brake wear has been light.
