Assistance please, title says it all. I have a 2000 F body with cross drilled rotors and OEM Calipers.Thanks in advance

probably Hawk HPS pads or EBC Yellows

Hawks here.

you would probably want to turn your rotors if they are used before putting in new pads
love my Hawk HPS pads. low dust and quieter than factory pads. stop better too.

I used Hawk HP+ on my Camaro. Work great but as advertised this pad compound is pretty dusty and noisy. Stops better than any pad I've had on the car though.

Thanks for responses. I'm using Hawks. I notice braking hard to shave off speed at full throttle brakes hum as I slow to stop. I full K MEMBER upper n lower control arms. I inspected rotors, looks fine. Wondering if car's hp/trq overpowering brakes?

The cross drilled rotors cause the hum you're hearing.

Which hawk pads?
Also get rid of the drilled rotors, they are not helping anything.

So nothing I should be concerned about then. What causes this? Thank you

I always thought slotted cross drilled rotors create a cooling effect on steel?

They do. The rotors that came on my Z28 from the factory warped, they replaced them and they warped, I replaced them (advance or autozone I don't remember) and they warped. I bought cross drilled off of ebay for if I can remember like $140 shipped for all 4 and I have been trouble Free for I would say 140,000 miles.

BUT THEY LOOK SO COOL.

I still run my cross drilled and slotted rotors on the street Blanks and hawks for the front for Auto-x though.

If you are concerned about squealing brakes then you might want to rephrase your question so that others more knowledgeable than me can chime in with better answer.

I have Hawk HP 5.0's. No squeaks. Good braking, and enough brake dusting to require wheel maintenance.

Nope.
Originally intended to help expel gasses from brake pads, however modern day brake pads don't gas out.
There is a ton of theory back and forth for cooling and improved braking, seems all is debunked by now. One thing is clear though, you have a greater chance of cracking the rotors...


False.
The rotors that come on these cars are pretty shitty, mine "warped" as well. The real fix is getting better brake pads. Im still running blank rotors and stopping WAY (high speed and auto-xing) harder than I was when I was on stock pads and have had 0 issues. Read around what the guys who track their cars run, you will see all blank rotors. Modern day race cars are using blank rotors as well...

All of this.

Neither cross drilled or slotted do much of anything to benefit modern brake pads. Slotted will help scrap away glazing on pads that get too hot, but if you're using performance pads they most likely won't be getting too hot and you'll just be burning through your expensive pads faster.

Blanks work best because the venting and vanes inside the vent is what cools the rotors, having less surface area or holes on the surface doesn't. In fact, they just give you less rotor mass to deal with the heat.

Quality blanks, quality pads, and keeping your fluid clean and flushed regularly (could even switch to dot 4 fluid) will be more than 99% will ever need. If that's not enough braking, get stickier tires.

As for what pad exactly, what do you mean by "hard braking"? Hard braking in autocross (tops 65mph) is not the same as road racing (120mph+). So the pads you would use would be different. What is the use for your car?

Running raybestos blanks, Powerstop evolution carbon fiber ceramic pads on front and ceramic rear pads. All through Rock auto for about the same as part store economy prices.

I agree but most new drilled rotors have quite a bit less holes in them then what you posted in that picture. This was done to eliminate the issue with cracking.

Double J

Brakes aren't squealing. I said it was a humming sound. The rotors show no indication of warping or cracking.

Drilled rotors are the devil on a road race car. Mine looked 10 times worse than the ones in the picture, one day at the track turned a brand new set into junk, cracked them all the way from the outer edge nearly to the hub, lucky they didn't come apart. I guess that's what happens when you stop repeatedly from over 150 on the back straight and 130 on the front.
