I have powerslot cryo rotors on the front, and regular powerslots on the rear with hawk hps pads all around. The hawk pads squeek like crazy on the rear. they just dont heat up enough. i can bed them in and the squeek is gone for a day, then its back. im looking for some alternatives here. i hear the stock z06 pads are pretty good. i want to stay away from ceramic.

 

Why the 2 different set of rotors? Could that be the prob?
I like my ceramics

 

I have a brand new set from brake performance. Ive never seen anything bad about them on here. Let me know if you are interested.

 

Interesting - I ran Hawk HPS pads on my '00 and never had any squealing noise. I was running Baer Eradispeed rotors all around.

On my '03, I am running the stock GM pads - no noise from them either.

 

have you tried cleaning it all with brake cleaner? maybe there is some grease or something on the rotors

 

I've always liked Raybestos Quiet Stops.

 

i disassembled the brakes and lubed the hell out of them twice and cleaned everything with brake parts cleaner. even took scotch brite to the pads and rotors before re bedding. no results. i didnt get the cryo treatment on the rear because they dont see as much heat as the fronts, so why waste my money.

 

I can suggest to stay away from the Brake Performance Ceramics. They create dust like crazy.

 

Are you sure the rears are hps? I got hp plus pads installed by accident on the rears on my vehicle and they squealed and dusted like crazy. Went to ceramics after that, and they were quiet with no dust, but didn't stop well. This round I have the hawk hps pads, and ensured they were actually all hps pads. They stop well and I have no squealing at all.

I would check that, and if true that your hps are squealing, maybe try the c5 z06 pads.

 

The ones I have are not Ceramics!!! They are Semi-Metallic

 

I just ordered Hawk HPS from Gene. Going to get these POS ceramics off my car. My friend is running the Hawk HP plus and they do squeak. Never ever put ceramic pads on a sports car.

 

Brake squeal is usually caused by vibration of the pads within the caliper. Usually new pads will not resolve the issue. I like the OEM GM pads and when I had a squeek issue I finally found a solution by using CRC Disc Brake Quiet which , when applied correctly, will isolate the pad contact with the caliper pistons and backing plates.

All I can say is that it has worked on all three of my cars.

 

I had ceramics and AC Delco drilled & slotted rotors on my 02 coupe. I never thought the ceramics were that great and I developed a serious brake pulsation. I just installed Hawk HPS pads and EBC slotted rotors for a huge improvement in braking performance. There's no squealing and minimal dusting; the slots add a little noise, but it's not at all annoying. I would advise against drilled rotors and ones where the slots extend to the edge of the rotors.

 

why not? My stock Z06 pads dust like a motherfukcer. I don't track my car, nor do I do crazy speeds north of 90 on the street so I do not need the best braking performance.

I WILL be putting on ceramic, ultra-low dust pads and I'm looking forward to how clean the front (and rear wheels) wheels will be. I expect braking to be decent as I have had good performance (and clean wheels) on my sport sedan with street ceramic pads.

 

do the rears dust a lot too?

 

My HPS pads have squeaked like a **** from the day after I bedded them. I bedded them properly and have relubed everything once. No difference. Mine only squeak at very low speeds right before I come to a stop. Maybe from 15 mph down to 0. I have Centric rotors plain face rotors.

 

Simple, It's called BRAKE FADE. I don't track my car, but I do drive a little hard at times. After three hard stops you will have brake fade. As in you are pushing the brake pedal as hard as you can and you are about to hit the car in front of you. Driving into the median because of Ceramic POS pads is no fun. Why would you want these on a Vette?
And they do dust.

 

not as much black dust as the front--but, they do dust more that I would like. It really is the hardest part of the car to wash. My Z rarely ever sees rain. When I wash her, I'm mainly washing off dust--dust on the paint and brake-dust off the wheels.

I really can't wait for ceramics. The stock pads work well--but hell, low dust is a MUST.


Dusting Characteristics
3. Dust build up on your wheels is caused by the high carbon and metal content of the metallic pad. Because these materials hold static electricity, they are also drawn to the metal in the wheel and brake system, resulting in thick, black buildup.
Ceramic pad compound have no magnetic properties to draw the dust to the wheel, so it is less likely to stick. The dust is also a light gray color instead of black. Any dust that does make it onto the wheel will be less visible.

 

After 3 hard stops I will have brake fade?--that is BS, I can tell you that first hand from experience on my G35. I'll make sure to only do 2 hard brake stops
As far as ceramic pads dusting--you can't tell bro. The dust is a light gray color instead of black. Any dust that does make it onto the wheel is less visible. Ceramics do not have static electricity to stick the dust to the wheels. The dust on my Hawks street ceramic pads on my G35 have minimal "invisible" dust, even after 2 wks driving so you see nothing but sexy forged 19" Rays wheels--NOT BLACK dust. I speak from experience as I have ceramics on my G35 in my profile pic and they perform GREAT. Read some more about dusting down below under "review."

I am NOT worried about brake fade(friction fade, mechanical fade, or fluid fade). If you think ceramic pads are POS, you in my opinion are ignorant. We are NOT talking about track-use either. Normal to spirited driving on the street.

I have stock cooling ducts to help cool the brakes, new brake fluid to prevent brake-fluid boiling that is worsened with moisture in old brake fluid, and from what I have read ceramic pads are less prone to brake fade due to heat. I do NOT have heavy, sustained braking during my drives so I do NOT fear hitting a car in front of me due to my non-existant fantasy brake fade.

Make no mistake, I do let this Z breathe a couple times each time I drive her (she is a beast), and I have NEVER needed my stock metallic brakes to "save me" from hitting a car in front of me.

I hit it and quit it long before I reach traffic in front of me.

I WILL be getting ceramics and there is nothing you can do about it

Washing my car will be a walk in the park and my wheels won't look black after 2 driving days

According to some reviews, metallic pads are more prone to brake fade--see red way down below from a review.


review:

Noise Characteristics
1. Metallic pads are noisy. Brake noise can be traced back to a harmonic vibration caused by movement of the pads due to rotor run out, and the amount of play in the brake mounting hardware.
Ceramic pads, while still affected by this vibration, raise the harmonic noise out of the range of the human ear. It's still there, but we just can't hear it anymore. The softness of the pad also helps absorb vibration much like the old organic compounds. Think of the difference in the sound of a quarter spinning on a table and a rubber washer spinning on the table.

Wear Characteristics
2. Metallic pads eat up rotors. The problem here is caused by the fact that metallic pads are harder than the other pad compounds. When the pad comes into contact with the rotor, the rotor will wear down along with the pads.
Ceramic pads are very soft, and only the pads wear. Because they are also more heat tolerant, they will not wear as fast as the metallic pad compounds.

Dusting Characteristics
3. Dust build up on your wheels is caused by the high carbon and metal content of the metallic pad. Because these materials hold static electricity, they are also drawn to the metal in the wheel and brake system, resulting in thick, black buildup.
Ceramic pad compound have no magnetic properties to draw the dust to the wheel, so it is less likely to stick. The dust is also a light gray color instead of black. Any dust that does make it onto the wheel will be less visible.

Heat Characteristics
4. Where the metallic pad shines is in its broad heat range. It functions properly at low temperatures as well as very high temperatures. Metallic pads do tend to hold heat, and brake fade due to fluid boiling still happens.
The ceramic pads' only weakness is low temperature efficiency. They need to be warmed a little during the first few stops. After warm up, they work well. Ceramic pads don't hold heat, so they recover from a hard stop much faster, preventing fluid boiling and brake fade.

 

This is the pad you should look at. Better stoping power than stock and 50%less dust.
