Brembos turning yellow..? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

After ~15 track days, the logo text on my OEM 2017 PP Brembos has started to turn yellow.

I know it seems a bit vain for a track car, but is there anything I can do to prevent or reverse it? My guess is that it's a no..but hey, worth a shot!

Not that I know of, paint is for cosmetic/protection from road salt/corrosion. Track only calipers are not painted and don't have dust boots either. I seen most cars on track with discolored calipers.

Of course there is a solution!
Have dedicated track day calipers and separate street calipers. You will get cred at the track for having obviously tracked brakes and you will get street cred for having bright yellow "Brembo" on your calipers while cruising about town.

Heh. Why stop at pads—I’ll just swap the whole brake system out between every event!

Noobs. Swap cars for trackdays.

Free range cats and dogs in the area?

Caused by heat. A majority of pads generate a ton of heat and it transfers into the caliper which cooks the paint. A high end brake pads has low heat transfer through the pad and reduces heat into the caliper and fluid. The energy goes towards the disc where it dissipates the heat more effectively than sinking it into all the surrounding components.

I don't know how to fix the discoloration (as in make it better), but I can tell you how to keep it from getting worse:

1) Buy titanium brake heat shields (Hard Brakes makes some that fit most calipers) which will help reduce heat transfer from pads to calipers

2) Run proper track pads with good construction (proper backing plate designs) will result in significantly less heat transfer into the calipers from the pads.

3) Duct your brakes to cool them resulting in lower overall temps for pads/rotors/calipers

4) Apply a high-temp ceramic coating over the brake caliper painted surface to help protect it from heat and debris (although most heat is from inside) and increase paint adhesion.

i suggest running an air tank on the car, and connecting air hoses near each caliper to cool them down.
