I'm not quite sure if this is a good thing or not...

I have a 11" 4-pot Fastbrakes.com Wilwood setup, and I do a lot of aggressive mountain driving. I'm using the Wilwood PolyMatrix D type pads, marketed as a club sport, performance street pad...

Tonight, after a particularly hard 9/10ths run down a steeper road, threshold braking along at most braking zones, it eventually got hot enough to throw not just a few sparks, but a fountain of them! This is according to a buddy of mine who was driving a few seconds behind me.

My question is... what does this tell me about my brakes/pads/disc? I haven't a clue what it does, except totally ruin my quest in keeping my car a sleeper...

 

Semi-metallic and Metallic pads have a tendency to do that under hard braking.
My Metal masters do that quite often.

 

welcome to the world of GOOD BRAKES And PADS!!!

 

it just smells wonderful when that happens

 

we run performance friction pads on the stock cars we race..
we glow the rotors red hot.... every race

 

I'm still waiting to hear what the problem is....

 

OT - Matt, doesn't unemployement suck? It's been about 8 months for me as well.

 

YAY fun with brakes! try that at night and show us th epics please!

I love my Hawk Blues!!!!!

 

Heheh... We're going to try and get it on videotape... I'm not sure if photos would do it justice...

I think it's just the metallic particles from the pads coming out, causing the sparking...

It's odd though--the rotor looks pretty much ok, and is the same thickness as before! I would have thought the rotors would be toast by now!

 

Bedding in Carbotechs on a country backroad late at night is pretty entertaining.

 

yes , yes it is

 

If you're in around Frederick (FRNX), you may even see me one night. It's a sweet ride from Darnestown to Frederick on 28/85. Deers suck, however.

We used to see our own brake sparks at night rallying the old 323 GTX. Of course sometimes sparks came from sheetmetal-to-rock contact.
