Brake pad compound compatability - Honda Prelude Forum

paulyg · 01-15-2006, 04:12 PM

My front brakes are worn out. It's time for some new ones. The current pads are AEM. I want to try some Hawk HP+. But I don't want to have to change my rotors. And I forsee a lot of problems with getting them cut b/c they are slotted. If I just put the HP+ pads on will I have problems? I have read some internet stories about breaking in a set of pads when the rotors still have some of the old compound on them and the new pads "sweating" or other bad things happening.

When I put my porterfields on i had no problems with my rotors. I just put some new street pads on with the stock rotors and have no issues. I don't think it will be an issue but it deffinatly wouldn't hurt.

I'd recommend switching to some inexspensive autozone blanks when installing new HP+ pads. Might as well replace the rear pads and rotors too. You're probably doing that already. I can't tell by the way you worded it.

Anywho, that would avoid most foreseeable problems.

i wouldnt get autozone blanks,.. they warp VERY easily, especially since paul does autoxing.

Not sure bout that. Billy uses autozone blanks on his racecar. [stalk..]

no offense to billy but he hasn't had to much track time in his car. He may not have put enough use on the rotors to cause them to warp.

Paul(G) - you should be able to get the slotted rotors machined, I had my Rotora BBK rotors machined in the past when I replaced pads, and it wasnt an issue for me. Just make sure they are still of servicable thickness.

I had my slotted + cross drilled brembos turned with no problems.

I used autozone front rotors all last year or the race car. They held up fine and lasted most of the year and I replaced them right before my last event of the season which means I got ~20 track days out of them.

I also use the AutoZone blanks. I haven't had a problem with them, yet...even with the aggressive spec-VR pads. Plus, they have a 2-year warrenty, so at the end of the season you can take them in and get a new set for free. If they ever warp or do crack on you, they'll be replaced and all you are out is the time to remove goto the store and reinstall.

There's nothing wrong with using the Autozone or other local auto store blanks. Tons of racers use them. But if you're looking for something more durable for DD and autocross use only (probably not going to crack due to heat abuse) it's probably better to get something of better quality. Brembo blanks are pretty darn cheap anyway.

Though I would pull off your current rotors and hit them with some sandpaper to rough up the surface a bit before putting another set of brake pads on them. Though admittedly I use GT-sports on the same rotors that I use the OEM brake pads on. I'm too lazy to swap the rotors out for autocross.

I have a friend that put autozone blanks on his 5th gen for daily driving and autox with Cobalt GT-Sport pads. For some reason both front rotors cracked all the way through. I've seen stress cracks, but these cracked clear through the metal.

It sounds like he didn't change the rotors soon enough. Those stress cracks get longer until the reach all the way accross the rotors and the next step is they crack through.

You are probrably right.

Though, they were only on the car for like a month or two. He may have gotten 1-2 autoxes on them.

This is really my thought process, and it's why I bought the Powerslots when I changed the OEM pads for the AEMs. But now I don't want to have to fork over another $175 just because I am changing pads. I do want/need something that will stand up to DD (Prelude is my only car), plently of autocrosses, and a track day or two. And the Powerslots have held up admirably to all of that.

Sounds like I should just take my chances with getting them cut. Even though there is the chance they will be too thin. Or I just get a new set of AEMs for the time being.

Thanks for the replys.
