Rear Rotors-cryogenically or cross drilled?

Post by jayslx1 » Sat Jul 17, 2010 8:07 pm

Has anyone tried cryogenically treated rotors on the back of their car? Or how about slotted or cross drilled?

Personally, I can't see the benefit or advantage of slotted or drilled rotors with any of our vehicles, as their intent is to vent in extreme heat situations. Unless you're autocrossing or towing significant amounts, there's no real advantage for the extra cost, IMHO.

IN terms of cryo-treated rotors, I tried those once. I had a full-sized conversation that was having heating issues on the front brakes, and thought the solution was cryo-treated rotors to keep the rotors more true and have less warping. I tried two different sets, and in both cases, the cryo-treatment caused normally "true" rotors to become warped just due to the treatment itself. And once you did enough turning of the rotors to get them "true" again, you cut a significant amount of thickness from the rotors, and the net value of buying the treated rotors was thus reduced since the rotors were thinner. So unless you're buying high-end cryo-treated ones - where after they make them "true" after treatment with enough thickness left - I'd look the other way.

Stock rotors should work fine for our vehicles - both front and rear.....

thanks for the advice. The reason I was inquiring is I purchased a set of Raybestos Advanced Technology rear rotors last April and it feels like the rears are now warped. I plan on trying a set of Centric's from Rockauto.com. I figure machining the Raybestos rotors will only be a temporary fix. I've always heard once you start machining a rotor it decreases the life of it, and it seems more cost effective in the long run to just replace the rotor.

Powerslot Slotted Cryo rotors matched with Hawk street pads is a good combo. Haven't put them on my 08 Taurus yet but I am running the same setup on two other vehicles of mine and haven't had any problems.

I found the cheapest place to get Wagner Thermoquiets for my '08 Sable & '08 Taurus is Amazon - believe it or not. I paid $44 for the front a couple weeks ago, and about the same for the rear last December. Included free shipping.

As far as rotors go, Rock Auto still has some Centric 'closeouts' for $20 a piece, or Raybestos for about $27. Shipping will cost you about $20 for these things, though. Shipping weight was 47 pounds for 2 rotors.

Update, we replaced the warped Raybestos rear rotors with Centric and used Akebono pads. The Centric rotors are thicker than the Raybestos so hopefully they will withstand the heat better. Owned the Five Hundred 2 years and have already had 2 rear brake jobs. Way to go Ford engineers...............

:( Powerslot doesn't make rotors for my 08 Taurus. I'm researching to see if anyone makes stainless steel braided brake lines for it though, doesn't help too much in stopping power but gives a stronger feedback feeling on the brake pedal.

I agree with you on the stainless lines.............I have them on my LX50........should be factory on all cars.

Yes, they managed to carry the same engineering problem over from 2005 to and including 2010. Anyone willing to bet it will be there for 2011? If it isn't already?

Does anyone make a quality, complete aftermarket brake system (at least rotors, pads & calipers) for the 2005-2010 500/Montego/Sable/Taurus line?

Baer or SSBC would be the only ones I can think of that might.
