cross drilled rotors versus oem

my oem's are warped (again)...but i play too much....i've used the ebc greens twice on my truck now, and i'm gonna try zeckhausen next go around....in slotted
 
Well,let's see,75,150 miles,Stock Rotors turned once,swithed to Porterfield Pads and still going strong !!It's getting close to turning the rotors one more time !!:dontknow:

i cant speak for porsche or ferrari. Mercedes, BMW, Volvo rotors are right at specs new. so by the time the pads wear down so have the rotors.

This bulletin contains important information about brake systems on Chrysler Corporation vehicles. It's designed to give you an understanding of the materials used in Chrysler brake systems. It will also familiarize you with some normal noises that may occur with a properly operating system so that you can clearly communicate these details to your customers. Many brake noises are normal and require no repair action. Unusual noises (not considered normal) should be investigated and repaired using approved procedures and Mopar replacement parts as required.

Because of environmental concerns, Chrysler, along with other automotive manufacturers, has eliminated the use of asbestos in most of its products. As a substitute, in some applications, Chrysler adopted semi-metallic brake linings which offer excellent performance. However, because of the metal-to-metal contact with semi-metallic pads, the noises generated by the brake system under normal operation may be greater than vehicles equipped with the previous asbestos linings.

During normal operation, various noises may be heard from the brake system, whether equipped with disc brakes or drum brakes, with or without ABS. To reduce the noise level Chrysler has begun introducing new non-asbestos organic (NAO) brake pads on several models.

COMMON BRAKE NOISES

Depending upon the local environment and individual driving habits, noises from the brake system may become apparent. The following noises are normal and are considered general characteristics of all braking systems (including other vehicle manufacturers). These noises do not indicate improper operation or malfunction in the brake system.

Grinding Noise

This noise is common with rear brake drums and on some disc brakes during the first few stops (such as after the vehicle has been parked overnight). This is primarily due to the formation of trace corrosion (light rust) on the metal surfaces during vehicle non-use or storage. This light corrosion is typically cleared from the metal surfaces after an few stops causing the noise to subside.

Trace Squeak/Squeal Noise

This typically occurs intermittently with front brake linings at medium speeds when you apply light to medium pressure on the brake pedal. It may also occasionally occur on the rear brakes during the first few stops and/or with cold brakes (especially morning) and/or high humidity.

Groan Noise

On automatic transmission equipped vehicles, a slight groan may be heard when coming to an abrupt stop or when allowing the vehicle to creep forward slowly with the brakes slightly applied.

ABS Self Check/Clunk Noise

This noise will occur when the vehicle is first started and moved at low speed (e.g. backing or pulling forward out of a parking space). A slight pulsation at the brake pedal may also be felt during the self-test procedure If any problem is found during self-check, the ABS system will deactivate automatically and the yellow "Anti-Lock" brake warning light on the instrument panel will light up. If the warning light comes on, the vehicle should be taken to a Chrysler dealership for immediate service. While the ABS system is deactivated (i.e. when the warning light is on) the brake system will operate as a conventional, non-ABS system.

Brake Pad Wear Indicator/Loud Squeal Noise

For disc brake pads with wear indicators, an audible continuous warning can be heard when the pads need replacement. This is not a malfunction as wear indicators are designed to perform in this manner. However, this sound does indicate that service is required. Customers that hear this noise should schedule an appointment with a Chrysler dealership as soon as possible to have the brake system inspected.

Noises that do not fit the characteristics of those listed above may be considered unusual especially when the noise becomes constant or when grinding, scraping noises occur, and should be investigated to determine whether a brake problem exists.

I didn't read the above long post...scuse me if I'm repeating anything.

I'm told that you cannot "turn" cross drilled and slotted rotors.... Is this true or not?

Well the dealer told me I couldnt turn the stock ones, He also on both of my last trucks wanted to sell me Rotors calipers and pads for $4800:mad: :mad: :mad: . I bought stockers for $800 ( Rotors) put a set of ceramic pads in the whole process including jacking the truck up took less than 20 mins per side, Now comes the good part I took the rotors to a brake store they measured them and turned for $20 bucks, looks like the dealer was trying to do me dry:D :D :D Now here we are again, they are not bad but feel like they have a slight warp.

it can be done on slotted I know, but you have to take a very slow cut. I'm not to sure about drilled.

HAHAHA that tsb is from 1996. :congrats: :congrats: :congrats:


No matter what you tell the customer they still think we have a magic wand in our tool boxes.
 
IMO, the OEM works great. I can't speak to slotted or cross drilled for these trucks but I have been running cross drilled on my Chevy 4x4 -- not a problem there and they work great to help slow down them 35's with 15x10's -- soon to be 17x9's. I don't think you can turn cross drilled -- too many holes for the lathe cutter to catch on? :dontknow: Maybe another way to turn them? :dontknow: I had slotted rotors on my MSRT8 (a TSB deal there) but traded it on the truck before I needed to address brake maintenance.
 
Make sure that you torque the lug nuts when rotating the tires. I have had issues with the shop monkeys putting the impact on there and tightning the shit out of a rim and warping it. ALLWAYS insist that they torque them.

alot of people have tons of different opinions thats what makes the aftermarket world great:D

the oem set up works very well, Dodge designed the pads to brake well under heavy truck conditions therefore you get alot of brake dust. they build a ton of pads so they cant really get into specific compounds.

The Rotors are jsut that, oem rotors, made to work with everyday conditions.

Zeukenhousen (spelling sux) works great, he sells alot of centriposi pads, and they work really well on no dust, and his rotors are awesome also, both are a very good deal for the $

and yes I sell the EBC rotors and pads, and with rotors your not gonna see any difference on the street, but they offer the dimpled and slotted to keep down the heat from the friction.

there pads, they offer many choices from oem replacement to track pads.
there pads work very well under all conditions, an a couple of there choices greatly reduce pad dust , while increasing pad bite, they achieve this because that is about all they do, make things to stop :)

I got the dimpled and slotted EBC's with EBC pads. No dust at all, no squeek, and it seems to stop me faster with more grab than the OEM ones. They look cool too :burnout:

Thanks to Stinker I have slotted and dimpled rotors with some EBC's in the works. I can't wait.
 
Stink is da man

Good choice. I think you'll be real happy with em.

I've heard to go with dimpled and slotted, not drilled, because the drilling weakens them? I'm still running oem and that's one of the next things on my list, so good question.

i have heard from the local performance shops that the cross drilled ones can crack over time like track braking and such
i have looked into getting the Brembo kit for mine but for 4k they better be dam good

the power slot rotors that ar slotted most ppl have those on rams and they all like them from what i have heard :marchmellow:
