Real life advantage of CRYO treated rotors

[gdsqdcr]

Folks

It is time for me to replace the front brakes on the Marauder (37K miles) as I am starting to feel a little shimmy under hard braking. I can not afford a nice set of Baer or Wilwoods ... so, I must do the cheap upgrade. Already have Hawk HPS pads and Stainless Lines. I am not gettting drilled or dimpled rotors, I want slotted, specifically PowerSlot slotted rotors. My question is, what are the real life differences between CRYO treated rotors and non CRYO treated rotors? The price difference is substantial, almost double.

FYI, I am doing all 4 corners at the same time.

Thanks!
Anthony

Just a thought.............

They are your brakes, don't cheap out on them. The life you save could be yours or one of your loved ones......

Not looking to cheap out. I will pay for the Cryo if they are truelly worth it. Not paying for hype though.

Get a good brand rotor and forget it, trust me, pads however are a different story.

[babbage]

command automotive. Police rotors - proven shorter stopping distance. lifetime warranty. I've warped them myself. They are not indestructible.

My suggestion: just buy new motorcraft rotors with severe duty pads.

I've had good luck with Command rotors and Hawk HPS pads on both of my Panthers. I wouldn't say that I am abusive, however I do have above average stopping demands.

I recommend them for daily driving. You should consider larger diameter race brake systems for true track duty though.

Before you make your decision look at the new NAPA auto rotors. I looked them over and really like them. Personally i'm running Powerslot D&S but the NAPA's will be the next when these need replacing.

I just installed the new NAPA Premium One rotors, so far so good.
I am taking the MM to Atlanta in 2 weeks for a 4-5 day road trip, I will put about 1800 miles on them and then I will let you know.
I bought them through my local Napa store for `$80 ea. With a good warranty, I used the Napa Severe duty pads in front, Hawk APS rears and TCE SS lines. Night and day difference.

[Mr. Man]

The cryogenic process changes the molecular structure of the metal thus making in wear longer. Check out this site for info and you can order from here too if you like. www.frozenrotors.com (http://www.frozenrotors.com). Guys on my Titan site like these rotors. Check for coupons too as I know there are 10 or 15% discounts out there.

NAPA rotors, never been happy with them on high performing cars. They are great on the Honda but I have not found them capable of taking the abuse. It is true, that I have not considered them for sevearl years, and technology changes ... so I can go look again -- but ...

Mr. Man

I have read the frozenrotor site a couple of times. Part of the research led me to a couple of 10% coupons but not 15%. I sent a PM to WCHAN and he responded with a good price. I just have to pull the trigger now on which set of rotors to purchase.

Thanks!

Napa just came out with a brand new rotor design for police market. Fits 03/04 Marauder. e.g. these are brand new you haven't tried them (nor have I..)

[BLACKMARAUDER04]

Are you sure you need brakes and not your rotors turned? I have 112,000
miles and still going on the fronts ( 3-5000 more before replacing them)

[SID210SA]

I agree....I have 98K on my originals and still have some pad life left.

[BLACKMARAUDER04]

What rotors did you end up getting?

Then skip any drilled or slotted bling rotors.

Good quality rotor castings will pay off, I saw the cutaway pictures of the NAPA rotors and was impressed.

CRYO treating is great in theory, in reality MEH the casting design and quality has more bearing.

Some of the theory regarding Cryo treating


Cryogenic processing
The field of cryogenics advanced during World War II when scientists found that metals frozen to low temperatures showed more resistance to wear. Based on this theory of cryogenic hardening, the commercial cryogenic processing industry was founded in 1966 by Ed Busch. With a background in the heat treating industry, Busch founded a company in Detroit called CryoTech in 1966. Though CryoTech later merged with 300 Below to create the largest and oldest commercial cryogenics company in the world, they originally experimented with the possibility of increasing the life of metal tools to anywhere between 200%-400% of the original life expectancy using cryogenic tempering instead of heat treating. This evolved in the late 1990s into the treatment of other parts (that did more than just increase the life of a product) such as amplifier valves (improved sound quality), baseball bats (greater sweet spot), golf clubs (greater sweet spot), racing engines (greater performance under stress), firearms (less warping after continuous shooting), knives, razor blades, brake rotors and even pantyhose. The theory was based on how heat-treating metal works (the temperatures are lowered to room temperature from a high degree causing certain strength increases in the molecular structure to occur) and supposed that continuing the descent would allow for further strength increases. Using liquid nitrogen, CryoTech formulated the first early version of the cryogenic processor. Unfortunately for the newly-born industry, the results were unstable, as components sometimes experienced thermal shock when they were cooled too quickly. Some components in early tests even shattered because of the ultra-low temperatures. In the late twentieth century, the field improved significantly with the rise of applied research, which coupled microprocessor based industrial controls to the cryogenic processor in order to create more stable results.
Cryogens, like liquid nitrogen, are further used for specialty chilling and freezing applications. Some chemical reactions, like those used to produce the active ingredients for the popular statin drugs, must occur at low temperatures of approximately −100 °C. Special cryogenic chemical reactors are used to remove reaction heat and provide a low temperature environment. The freezing of foods and biotechnology products, like vaccines, requires nitrogen in blast freezing or immersion freezing systems. Certain soft or elastic materials become hard and brittle at very low temperatures, which makes cryogenic milling (cryomilling) an option for some materials that cannot easily be milled at higher temperatures.
Cryogenic processing is not a substitute for heat treatment, but rather an extension of the heating - quenching - tempering cycle. Normally, when an item is quenched, the final temperature is ambient. The only reason for this is that most heat treaters do not have cooling equipment. There is nothing metallurgically significant about ambient temperature. The cryogenic process continues this action from ambient temperature down to −320 °F (140 °R; 78 K; −196 °C). In most instances the cryogenic cycle is followed by a heat tempering procedure. As all alloys do not have the same chemical constituents, the tempering procedure varies according to the material's chemical composition, thermal history and/or a tool's particular service application.
The entire process takes 3–4 days.

Napa's "Ultra Premium" rotor is Raybestos' "Advance Technology" rotor and they are made well.

As Babbage said they have a new "police specific" rotor at Napa. http://partimages.genpt.com/partimages/1066864.pdf Which differs slightly from Raybestos' info. http://www.raybestos.com/wps/portal/raybestos/c1/jY7LDoIwEEW_yLSU6YMtYKCUtEA1Ah vCwpgmAi6M3y8YNdEFemd5cuZe1KL5 xv7mTv3VTWN_RjVqWaeSmGbSSsFB6q KkscXPzLxhnYYc_DBTdgvWo1XICnjx f2ympCGa4AS0wIQGhdGU4cDjP-zDsna9_cFX_i88UiLfxUkaAVhrKp-U_of_vYDyN9fpNBzRZdjX2MnNHanqi m4!/dl2/d1/L2dJQSEvUUt3QS9ZQnB3LzZfS0dENU pJU0k4NzRJTlBRNURTMDAwMDAwMDA! ?WCM_GLOBAL_CONTEXT=/wps/wcm/connect/affinia_websites_content_en/affinia.websites.content/Products/General/raybestos/Advanced+Technology+Police+Pat rol+Products/Police2 (http://www.raybestos.com/wps/portal/raybestos/c1/jY7LDoIwEEW_yLSU6YMtYKCUtEA1Ah vCwpgmAi6M3y8YNdEFemd5cuZe1KL5 xv7mTv3VTWN_RjVqWaeSmGbSSsFB6q KkscXPzLxhnYYc_DBTdgvWo1XICnjx f2ympCGa4AS0wIQGhdGU4cDjP-zDsna9_cFX_i88UiLfxUkaAVhrKp-U_of_vYDyN9fpNBzRZdjX2MnNHanqi m4%21/dl2/d1/L2dJQSEvUUt3QS9ZQnB3LzZfS0dENU pJU0k4NzRJTlBRNURTMDAwMDAwMDA% 21?WCM_GLOBAL_CONTEXT=/wps/wcm/connect/affinia_websites_content_en/affinia.websites.content/Products/General/raybestos/Advanced+Technology+Police+Pat rol+Products/Police2) So it appears the "police" offerings may differ slightly.



The Napa "Reactive One" and Raybestos' non-directional performance units appear to be the same are quite unique here's the rears.

Here's mine. They are the Reactive Ones from NAPA.
I'm at 3000 miles so far, I am totally happy with them.

Many police departments use cryo treated rotors. They are less prone to warpage.

[boatmangc]

I found this a long time ago, I have found it to be useful information.
Especially the break in procedure.

What rotors did you end up getting?


Got put on hold temporaily. The accident put the car out for a bit and because of needs at work, I have been driving the truck. I am no hurry to do them as my last check showed still sufficient pad left (more than I thought there was going to be).

I will be getting the CRYO powerslots though.

Thanks!
