i was told at my last inspection that i would need new rear rotors and pads within the next 8-10k miles.. well i am now over that number and i can notice a stopping difference. i am looking to get a set of cross drilled/slotted rotors.. i dont even know where to start looking or what is even a good brand.. or if anyone even makes them for the HD's.. i do more hauling then towning.. i usally have my pay load maxed out and then some.. when i do tow. i am pulling my travel trailer which has a gvw of 11k. can anyone help me choose a set of rotors for my truck?? im looking for good set, but dont want to go bankrupt buying a set of rotors.. thanks in advance

How to properly fit rear brakes http://www.dieselplace.com/forum/showthread.php?t=313310

Drilled and/ or slotted are snake oil.

I wouldnt agree that drilled or slotted Rotors are "snake oil". I recently replaced my rotors with EBC Slotted Rotors. I hated to spend the money on brakes but I had to find a solution to the spongy feeling and constant squealing. They have been one of the best investments I have made to the truck. I'm going to order some EBC Red Stuff pads to finish it off.

My Durastop GM pads never squeal.
Rotors do not affect the "feel" under 99.99% of your driving.
Regardless of the brand of components chosen, PROPER fit and lube is key.

Not snake oil. They have a purpose.

The purpose is to allow the pads to out gas as they get hot. When the gasses develop, if there's no place for them to vent, they will cause the pad to float above the rotor, thus decreasing braking effectiveness.

While there may not be a noticeable improvement in daily driving with no significant load, there should be a noticeable improvement when towing heavy loads, and using the brakes excessively going down grades.

If it was snake oil, NASCAR, F1, and Indy, along with a whole host of other race teams, wouldn't be using them.

I should clarify my comments are regarding ball milled (or cast slotted) rotors. I wouldn't run a drilled rotor, they crack between the holes.

If your "gassing" off the pads, they're not street pads, period. Ceramics pads do not "outgas". Hell, they're probably not even semi-metallics, but rather, they would be an organic compound.

Don't even think for minute that your examples are running "street" pads. Besides, they toss their rotors every 500 miles.

You're sure that ceramic and semi-metallic don't out gas? Absolutely positive?

I ain't betting lunch money, if that's what you're asking.

Good thing.

Hemcall is right, slotted or drilled rotors are not necessary for one of our trucks, pad wear is greatly increased which also requires running much "harder" pads which also increases rotor wear.

I don't think NASCAR rotors are allowed to be drilled or slotted because it weakens them and makes a rotor explosion more likely, they use a rotor that is similar to a stock design with the venting in the middle (dramatically larger however).

Formula One Rotors are carbon fiber with carbon pads. (Also not drilled).
