Hot Rod Brakes

[glockmail]

Put these on my Explorer a while back:



The OEM and replacements rotors kept warping. I do a lot of mountain driving and its hard on brakes.

As I recall, a person who shall remain unnamed told me that "the holes and slots won't do anything to make them work better" or some other shit like that. I am pleased to report that he has yet again been proven wrong, and I have been proven right: after over a year the new rotors are still true.

That's the difference when you have "car and driver" knowledge vs. hands on.

You're fooling yourself. If you're warping OEM rotors you're driving poorly. The average Joe won't see any measurable benefit from blowing money on slotted or drilled rotors. A good set of pads is really the best brake up grade, other than training the driver to brake correctly.

Cross-drilling your rotors might look neat, but what is it really doing for you? Well, unless your car is using brake pads that are 50 to 60 years old, not a whole lot. Rotors were first “drilled” because early brake pad materials gave off gasses when heated to racing temperatures - a process known as “gassing out”. These gasses then formed a thin layer between the brake pad face and the rotor, acting as a lubricant and effectively lowering the coefficient of friction. The holes were implemented to give the gasses somewhere to go. It was an effective solution, but today's friction materials do not exhibit the same gassing out phenomenon as the early pads.

For this reason, the holes have carried over more as a design and lightening feature than a performance feature. Contrary to popular belief, they don't lower temperatures. In fact, by removing weight from the rotor, the temperatures can actually increase. The holes can actually create stress risers, allowing the rotor to crack sooner, and make a mess of brake pads - sort of like a cheese grater rubbing against them at every stop. Want more evidence? Look at NASCAR or F1. You would think that if drilling holes in the rotor was the hot ticket, these teams would be doing it.

The one glaring exception here is in the rare situation where the rotors are so oversized (look at any performance motorcycle or lighter formula car) that the rotors are drilled like Swiss cheese. While the issues of stress risers and brake pad wear are still present, these racing teams are replacing brake pads on a much more frequent basis - sometimes every race weekend. Drilling is used to reduce the mass of the rotor in spite of these concerns. (Remember – nothing comes for free. If these teams switched to non-drilled rotors, they would see lower operating temperatures and longer brake pad life - at the expense of higher weight. It's all about trade-offs.)

Of course you paid money for shit. You want shit to work or be better. It's human nature.

Thanks for quickly falling into my trap and verifying that you have "car and driver" knowledge vs. my "hands on". Your theories have been trumped by my actual experience.

If you experience a ghost, I can't tell you it's not real. If you've seen Santa flying across the night sky, no amount of reason can convince you otherwise. If you drop acid then make love to a magical unicorn, that's all you.

You can believe what you want to believe. Your real-world-experience doesn't trump physics.

You're knowledge of physics is limited to what you've read in a magazine. Mine's from engineering school (BS- Cum Laude) backed up by actual experimentation.

My the coffee's good this morning.

Emphasis on the BS.

Wow Marty I'm impressed. I hope you're working out along with dieting. Get some muscle on you to impress the babes, and some stamina to impress them still more.
