Hawk HP+ courtesy of Luke... Worth the noise? - Page 2

I'll add my input here, but it's the same as most of the others, slight squeak at sub 5mph stops, lots of dust, excellent performance on the track.

They are a great performance mod to the car. THe first time you REALLY stop hard, you will have a big smile on your face

Pretty much my experience. I am on my second set of HP+. I really like them on the street, but they are especially impressive on the track!

Thanks for the quick replies, guys. I guess to most there is *some* noise, but not enough to be concerned about. And another thanks to Luke at Lindsay

I put Hawk Blue's (with stock rotors) on my V for a trip from Cleveland, Ohio to Summit Point to Myrtle Beach, around Dragon's Tail in Tennessee, back to Cleveland, Ohio. NEVER heard a squeek, evvar. (looooots of dust though)

None of you guys have any stopping issues with HP+ pads when you initially hit the brakes?
I'm in need of some rotors and I would like to have a fresh set of pads on them while I am in there. I've been talked out of getting the HP+ because they need a little heat in them to perform. Cruising for a while on the highway can cool the brakes down to ambient temperature. If for any reason you need to hit the brakes hard, the first couple seconds may make the difference between avoiding and hitting something. It seems that race pads when cool/cold, have less stopping capability compared to stock or street pads at the same temperature. When hot, that is a different discussion.

Great question - I too would like to know the answer. This concern is the only reason I have not yet gone to HP+'s.

I actually had an opportunity today driving into work to test the stopping power at highway speeds, and was very impressed. Damn near drove the front end into the asphalt. However, I'm still new to these things so I can't answer that for sure.

It's the around town driving I am concerned about. You can be stop-n-go traffic (welcome to Jersey) where the brakes have no heat in them. There's that instance you need to hit the brakes to stop in a very short distance at low speed.

In track conditions, the HP+'s do seem to need a lap or two to get to a nice consistent stopping power. With that being said, under emergency conditions, even when cold, I can get ABS to kick in right away with them.

The best would be for you to find someone with hp+'s in their and take it for a quick trip to see if you like the feel. If you make it down to the DC area, I will gladly let you take mine for a spin.

I don't notice any loss of stopping power of the hp+ when cold. Blues, on the other hand...

thebigjimsho · #26 (**permalink**) 03-14-09, 12:19 PM

And that's with me driving in near freezing temps...

Based on my understanding of brake pad technology, if the hp+ does not represent a compromise in terms of stopping power when cold it must represent some level of compromise in terms of fade resistance under frequent use. Simply put, you there is no such thing as a no compromise brake pad. So where does that put the hp+?

well, there are a lot reasons pads fade. but to look at a graph of a pads proper operating temp, you usually see a steady performance curve and then suddenly, a tail-off in performance when worked up. I think that can also apply on the lower temp range.

Like a brake system that's wet and cool, you can feel the pads do nothing for a split second until it dries out and then, like a turbo, it bites. Same thing for the hawk hp+. It probably does do poorly when cold, in theory. but when you're talking ambient temps that seem wild to us in a 50 degree swing from 30-80, our braking system can go from near ambient to a few hundred degrees in a very short amount of time. you'd be up to proper operating temps almost instantaneously...

race pads, on the other hand, need to get up well into the hundreds of degrees to work effectively. I wouldn't run my Hawk Blues on the street unless it was a quick jaunt for fun...

Thanks. From what you are saying the hp+ works fine on the street and I think I will give them a try. My concern is not really the first stop sign on a morning drive, it is rather missing the idiot that cuts in front of me when I have been on the freeway for 30 minutes without touching my brakes. At that instant I will not have the luxury of pre-heating the pads.
