Why increase Brake Pad Friction

[tk90]

I suppose this question first hinges on another:

In general, are a car’s brakes strong enough to lock the wheel?

Given that locking the tire (skidding) is detrimental in terms of stopping distance, and given that a brake system can effectively lock the wheels, is there a benefit to increasing CoF between pad and rotor?

Meh. Pads and rotors for a Veyron are something like $50,000.

That has nothing to do with where track pads 'start', which still isn't $1,000.

nothing to do with carbon or ceramic discs. why are you disputing the obvious?

here is another populal race pad ($1100 both axis):

why are you disputing the obvious

Providing examples of brake pad sets that cost $1,000 does not confirm that what you said, which was:

high perf/race pads start at $1000

How about we get back on topic, and you explain what the actual problem is that you're trying to solve, or the question you're trying to answer, we so the forum can potentially help you solve your problem or answer your question.

Well, I've always been disappointed in the amount of "bite" in my pickup trucks 4 wheel disc brakes. It seems to take quite a lot of force and pedal travel to get serious braking at or near ABS activation. I don't try to do that often but when traffic comes to a complete and unexpected stop I would like more aggressive brakes. So at 80,000+ miles it's finally time for new rotors and pads all around and I'm going to pay about double what OEM rotors and pads would cost for upgraded aftermarket parts. Note, there will be no increase in size because that would involve considerably more cost. All the reviews on multiple sites say there will be a very noticeable difference, I'll let you know. Probably be a couple more weeks before I do it.

Well, I would say the new aftermarket high friction pads, rotors and fluid flush didn't make much difference at all. Brakes seem about the same as before. Part of the bedding in process of the new pads was to do moderate 40 mph to 10 mph braking followed by 35 mph to 5 mph braking in rapid succession without letting the brakes cool. That was enough to get some fade. Should have saved some money and used OE parts or gone the more expensive approach with bigger rotors and new calipers. I was looking at the brake specs on a new truck and in 10 years they have not changed them one bit. I don't understand how tow ratings can increase year after year and the brakes never improve.

I don't think the truck brakes are the limit for GCW, as the assumption is that any trailer over 750 kg (as an example for my SUV) has brakes. They are involved in GVM calculations, but I don't know how that calculation is done. On most vehicles I've worked on the actual limit was gearbox/diff temperatures up one particular mountain.
