Would it be dangerous to drive with a brake pad compound that becomes effective say after 50 degrees celcius?

 

I'm not sure what you're inquiry is exactly, but for street driving you should run a street pad. It is counterproductive to run racing pads on the street.... your brakes won't ever get hot enough to become effective... they will still work, but nowhere near their potential.

 

they're categorized as street pads by endless but higher end street pads.

The Super Sport line of Endless pads are the high end street pads. I'm pretty sure the CCA's are pure race pads so yes, they would be quite dangerous on the streets. 50°C is about 120°F so they would be operating below their temperature range during normal driving. Street pads are usually good from 0° on up.

 

i don't think so

 

Endless Type CC-A

Type CC-A debuts in 2006 as the ultimate semi-metallic ceramic carbon compound for the street. Although this compound is produced with semi-metallic materials, it is produced with focus on the street-type driving environment with impressive pedal feeling. Amongst the CC line-up, the CC-A compound is the least abrasive on disc rotor surfaces. Braking force is effective from low temperatures and the CC-A produces the least amount of noise and dust amongst the CC series line-up as well. With a stable and smooth Mu, it is the perfect compound for high-powered and heavy-weight cars on the street. With the growing popularity of heavier, high-powered vehicles being produced by auto manufacturers as well as progressive improvement in the quality of high-gripping radial tires, the CC-A brake pad compliments these characteristics perfectly with superior braking force and a high level of controllability. A high performance brake pad at a reasonable price is born.

I stand corrected.

 

So how much lower wiill the coeff of friction be when at 0 deg celcius ? Really low or just a tad below spec?

 

Im not sure. But i have Hawk HPS, and although they're technically a street pad, they absolutely suck when cold.
