Hawk Pads

[Vegas69]

Looking for any input on Hawk compounds. Anyone happy with their setup with a mix of auotcross and road racing in mind? Unsatisfied with my Wilwood pads and their cold performance.

I will have some info for your soon. I have seen Carbotech on the corvette forum and lots of people swear by them...Tobin at Kore 3 told me to give them a call. They happen to be 15 minutes from my house. Anyway, I got a set of their Ax6 pads(autocross pad). The cold Cf is .52. Suppose to be easy on rotors, can drive them on the street but may be noisy with a little dust. If you are concerned about noise you can run their bearcats on the back. They stated these pads have won a number of national solo II events. They said for track for my car to use the XP12 on front and XP10 or XP8 on the rear. State to use a different compound on the back on a solid axle car to keep it for wheel hopping.

I will let you know about the noise, bite and dust by this weekend.

i have been running 9012 blue on front and hp plus on rear, i like a less aggressive bite on my rear brake pads. the 9012s are alittle hard on rotors but the initial bite is well worth it.

Thanks Dudes...:D

yesterday. Todd you know the problems we have had with not liking the feel of our brakes. Well I can finally say I am more than please with the feel and performance of my brakes. What a difference a good pad makes. The Carbotech Ax6 pad is outstanding. It dusts more than the BP10 but not as much as say your BMW. somewhere in between. So far no noise and it stops like crazy. I also changed fluid to a Brembo low compression and the feel of my pedal has never been better. These will be the only pads I run on the street and autocross. I will get another set for the track that will take that kind of heat. Probably the Carbotech XP12's on front and XP10's on rear.

Nice! :thumbsup: The only time I've really liked my brakes was on the road course. I'll call them soon. What do you think about going to a 1 inch master with these pads?

[Payton King]

from Wilwood. I personally would get a set of these pads and also try the Brembo fluid. I think it will give you the feel you are looking for...

I had a different type of fluid and my pedal was almost spongy for lack of a better term. The fluild changed the feel of my pedal completely.

Why are you looking to increase the master size...fluid volume for pad knockback?

That's some very interesting info about the brake fluid. I've been disappointed with my spongy pedal using Prestone DOT 5 Synthetic. After reading your feedback, I've gone ahead and ordered some of that Brembo SPORT.EVO 500++ brake fluid from Amazon.com and I'm going to give it a shot next weekend. Hopefully I'll notice the same improvement you did. Amazon had the best price I could find: 3 bottles shipped for $41.

I've got a good firm high pedal except when racing when it drops but stays firm. You guessed it, the 1 inch bore would cut the knocback in another 1/3rd. I have one that was traded to me. I'm going to try the pads first and go from there. I didn't know any fluid was compressable?

[Payton King]

but it did make a difference. Not sure which Brembo fluid I have but that sounds right. Look on carbotech website and you will see what I used.

If you are using the DOT 5 stuff that is a silicone based fluid and should not be used in a performace situation. Make sure you flush it well to get all of that stuff out. I would purchase some DOT 3 or 4 stuff and use it to flush it out and then flush that stuff out with the Brembo fluid.

I was running the Prestone DOT 4 synthetic and apparently it sucks. LOL

Per Carbotech, I took a 2 inch abrasive disc and went over the rotors to get the old brake material off before I put the new pads on and bedded them in.

[Payton King]

If you go to the 1 inch master you could always drill a hole higher up and increase your pedal ratio to get the effort back down and still have the fluid volume you are looking for...

[Vegas69]

One step ahead of you:unibrow: I already drilled a hole but it marginal if there is enough clearance for the pin inside the pedal housing and it decreased the travel of the master cylinder piston to just shy of the master cylinder piston travel. I'm running the Wilwood old fashion dot 3 with a hint of Autozone dot 3 since I ran out last time. I'll do the pads first and take it from there.

[GregWeld]

I've seen people add a hole too high up (in an effort to get more pedal ratio) -- and then they go "over center"... once the pedal/rod goes over 90* --- you're REDUCING pressure on the master... NOT GOOD! :rofl:

In my old road race Mustang, I used to run either the Ford High Performance fluid (in the blue can) or Motul fluid. Both are excellent. I ran PFC pads and then switched to Hawk blacks. I much preferred the Hawks.

It may be different with the larger, newer brake systems, but my Baer A-Sedan brakes with PBR calipers had to be bled every 20-40 mins of track time. Rotors lasted about 10-12 hours on track.
