What causes the calipers to turn brown?

[alex_alex]

For those of you who've seen lots of track days, and now have "brick red" Brembos, or "brownbos", what causes this?

Is it permanent?

[apexstrafer]

heat.

and yes.

Yep, drive fast at the track = brick red Brembos. Also have seen the diamond star hubcap try to melt out of the center of the stock wheel ;-)

One of my hubcaps started to melt.

u guys mean "center cap" im sure. Hub caps or those plastic wheel covers for people too poor to buy aluminum/chrome wheels.

[apexstrafer]

same diff. it "caps" the "hub", so hey... ;)

[alex_alex]

that sucks. so theres no way to clean up the brown mess?

[alfredob1]

Your baking/burning the paint, you can't clean that off. You could always have the calipers stripped and powder coated, when they get really brown.

BTW, if you run some sort of cooling ducts it goes a long way to help keep them red.

[SSwest]

Hell, all that showes is that you actually use the car, right?

[apexstrafer]

bingo.

burninated brakes are a sign of testicular fortitude.

oh ya mine are brown and its going to be a lot of fun when I take it to the dealer because one of my brownbos is acting fucked up, im just going to tell them I rolled through some shit.

You are supposed to take those centercaps out when you go to the track.

Regarding the brakes, brownbos are the badge of those who actually drive their evos :twisted:

Bleed your brakes and let the fluid get all over the calipers - that'll fix it the rest of the way....(it won't be brown any longer - it'll be gone.
And if your melting plastic wheel caps you may want to repack wheel bearings at some interval...that brake heat gets to the bearings and will cause premature wear.

[alex_alex]

anyone have any pictures of brownbos?

The EVO hub/bearing is a sealed unit, when the bearings show significant wear, they are just replaced as an assembly. On the 2G Eclipses, which use the same design, we replace them every season for the guys who do monthly track days, as we have seen failures of the 2G hubs when run on road circuits.

Brownbos are the color EVO brakes are supposed to be.

John, did you get my e-mail? Ive been trying to get a hold of you for while.

i think that sums it up right there, and a great way of putting it too.

[Muramasa]

Can anyone show a picture of a brownbo?

[alex_alex]

bump

Come to an EOC event and we will show you how to "mod" your brembos into brownbos :twisted:
