Anyone know of any big brake kits for the F150? Or an upgrade disc that wont warp with 22 inch wheels?

 

check these out....some are pricey but worth a look!

this one is a full replacement big brake kit which is very pricey

Brembo Gran Turismo Drilled Brake Kit

this one is a replacement rotor that will allow use of your stock calipers.

Baer Eradispeed Rotors, Baer Eradi Speed Plus 1 Rotors

hope this is what you were thinking of

Exactly. Thanks! I was also hoping of some real world reviews as well.

 

haha cool. I have thought about doing something like that but it is just too much money for me to do. Wish that I could give you a review or something.

 

I have had great luck with powerstop drilled rotors not warping....I've had them on a few vehicles in the past and am planing on putting them on my current truck in the next few months

 

With regards to rotors, I have previously run Brembo OEM replacement rotors that are cryogenically treated at Diversified Cryogenics, making them almost as hard as stainless steel. Unfortunately, Brembo, Powerslot, Raybestos, Bendix, Hawk etc. are all purchasing their rotors from the same foundary in China (with the exception of the $300 each composite high end units for Ferrari, Porsche, etc). I am presently running “Frozen Rotors” from Diversified Cryogenics. They purchase the highest grade rotors made, laser mic them for quality, scrap the ones that are out of spec and cryogenically treat the good ones which are now as strong as stainless. They will also slot and cross drill the rotors for you. Their service, price and quality is excellent as well.

For street use, slotted/drilled rotors are just “cheese-graters” for the brake pads IMHO, because unless you are involved in true racing conditions, the brake linings do not produce the gases which slotted/drilled rotors are designed to relive. In some cases, brake testing indicated reduce brake efficiency in street-based operations using slotted/drilled rotors when equal comparisons were made. The staff at carbo can speak to you as well regarding those options, but I am very satisfied with the performance & wear of these products.

 

Where did you hear this??? I ask because the last time we had this debate someone said that gm and ford stock rotors came from there too and we pointed out that wasn't true.....

 

I'll agree with you that gasses aren't the problem with street vehicles....which i'll agree that slotted rotors don't do much good.....but drilled rotors run cooler, which is a problem on our trucks....hot rotors are the main cause of warping....

And i asked once before and never got an answer, is there a link to this testing that shows reduced efficiency??? I ask only because every test i've ever seen has shown better overall brake performance from them....

 

I did not state Ford or GM- the aftermarket! Call Diversified Cryogenics and they will confirm.

 

1. As I stated to you previously, search on line or call Carbo or Diversified and speak directly to an engineer- they will confirm everything I have stated.

2. All brake systems (pads/calipers/rotors, etc) have an operational temperature- both minimums and maximums. If you are operating within the range, even if the cross drilled rotors cooled the temps by lets say 10% (which is impossible on a street vehicle), that would be 90 degrees F- since 99% of the oem systems have max operational temp ranges of 900 degrees F; The optimum temp is around 600 degrees F- so if you cooled by 10% (which is impossible in a street vehicle) you would be reducing temps by 60 degrees.

Unless you have installed a pyrometer on your vehicle and have verified that you are operating at or near 900 degrees F, to install cross drilled rotors for the sake of cooling is worthless- the products are designed to operating in a specific temperature range (OEM's 0 to 900 degrees F- with the exception of hipo cars such as Corvette, Porsche, etc.).

What does make a difference are the materials ability to be resistant to temperature change created at the point of friction- for rorotrs that is a case of metalurgy, for the linings that is a case of material types.

This is why I use "Big Rigs" such as Fire Engines as an example....

Whether you look at an F150 or a Pierce Fire Engine, both have 4-wheel disc brakes...
The rotors are designed to operate in a specific temp range and the specs call for the rotors to be of certain size, diameter, thickness, etc. (of which the brake linings must be designed for as well) based upon the performance requirements/demands.

While cross drilled rotors are available for these vehicles, no mfg uses or recommends cross-drilled units for these big rigs- where these vehicles brake systems #1 destructive force is heat!....because of cost versus gain- there is no gain by using crossdrilled or slotted rotors in street applications.

In previous threads I gave you links, contact names, phone numbers- use them or shut up-

YOU ARE SIMPLY A MESSENGER OF ONE OF THESE AFTERMARKET COMPANIES WHO IS DISPELLING MARKETING MYTHS FOR THEIR PRODUCTS!

ENOUGH IS ENOUGH!

 

I don't see how you think i should call the company which is a direct competitor to the products i have used with great success and get their opinion on their competition....

IF heat is not an issue on street vehicles....why is there such a common problem with warping rotors?

 

Can someone get to the bottom of this, please?

 

6,000 lbs trucks

big freaking rim/rubber combos (lots of rolling weight)

add some hard braking...or prolonged braking...or stop n' go traffic...sudden hard stops




it don't take much to warp a rotor. Especially if you do any of the above...or any combo of.



btw, how is a slotted rotor going to "cheese grater" the brake pads?

 

So are these other rotors better?

 

Heres the problem......companies making drilled rotors say they work better, improve stopping distance and run cooler...

Companies making non drilled rotors say they don't stop as well, that running cooler doesn't matter, and that they don't have an application that needs them....


All i can speak of is my personal experience.....


I've had cross drilled rotors on my 95 F-150 which had 35's on it....and warped the stock rotors twice.....put cross drilleds on and never warped them again...

I put cross drilleds on my fiance's 01 grand am after warping stock rotors, napa rotors, and brembo rotors......now 50K miles later still no warping (and it stops way better than stock, although yes...i did put on ceramic pads)

I've had cross drilled rotors on my 05 yamaha r6....

Have put them on a G6 for a friend and also a mustang for another friend....all of which drive like idiots and warped stock rotors....




As for the cheese-grater comment.....go run your hand over the back of a cheese grator (flat surface).....does it get cut up??? no because theres no way for the pad to deform down into the hole and catch on the edge......my fiance's car has had the same pads on the front since i did the brembo rotors....and now the cross drilleds with almost 60K miles on them and they're still probably 40 percent left....



As for rotor choice...its a decision you'll have to make on your own.....look at the rotors available, look at what vehicles run cross drilled rotors (high performance vehicles) and decide if they'll work well for you......I know my trucks getting a set later this summer....
