Warping Automobile Disk Brake Rotors Are Preventable

In the aircraft and aerospace industry, the standards required for various components, parts, and specifications are considerably higher. Everything built for the aircraft and aerospace industry is light and strong. It is the “AND” part of that sentence that makes the parts expensive, not the “light” part. Automobile manufacturers today who build high-performance and sophisticated vehicles understand the “light” part, but not necessarily the “strong” part. But what they do understand is how much force can be applied to these parts before they succumb to failure.

Today’s brake rotors (or disk brake system) are built very light with advances in technology such as slotting, cross-drilling, cryo-treating and many other advances to allow the brakes to breathe better and last longer. However despite all this technology that goes into the rotors, they are still not strong enough to withstand a mechanic’s error. How often have you had a car pulsate when applying the brakes? The reason this happens is because the lug nuts on your wheels were not torqued down to specifications set out by the manufacturer. Every mechanic shop you walk into, you can always hear the distinctive sound of the air wrench being used to loosen and tighten parts and lug nuts. These air tools are capable of putting out an immense amount of torque, but that is where the problem starts. The torque setting on these air wrenches are preset to a single setting (usually the strongest), never changed, but used to tighten down everything on your car. BAD!

Today’s modern vehicles are built almost like airplanes and have very acute specifications that must be followed. The most commonly made mistake by mechanics and car owners are to over-tighten the lug nuts on the wheels of their cars. Some even go as far as jumping on the tire wrench to ensure that the lug nuts are “tight” and that the wheels will not “fall off” while driving. However, over tightening your lugs will lead to premature failure of your brake rotors as seen by warping or deformations in the rotor. It may also lead to wheel bolts “snapping” when over-tightening the wheels stretches and weakens the bolt.

It is therefore important to ensure that your lug nuts are tightened to the appropriate specifications and to do that, there are several things you can do. For most vehicles, the lug nuts need to be tightened down to 70-100 ft-lbs using a good quality torque wrench. However, you do not need a torque wrench to tighten your lug nuts correctly.

The approach I have always taken is to tighten the nuts as tightly as can be done with your fingers first. Then taking a tire wrench, tighten the nut without apply much effort until you feel some resistance. Then simply (without jumping on the tire wrench), put your body weight on the wrench until it stops turning. You do not need to jerk your body to ensure that there is more room to tighten. In general, if you follow this practice, you will put about 80-90 ft-lbs of torque onto the lug. Do this consistently for all your wheels to ensure that your brake rotors have maximum life. However, for best results, I still recommend acquiring a quality 1/2″ drive torque wrench, my favorite being the Neiko Pro line that I use religiously for every mechanical work conceivable.

It is a worthwhile investment and they typically range in price from $20-40, which is cheaper than a single brake rotor for your car. The brakes and wheels are the most important components of your car and therefore, requires the most care and attention. Go check your lug nuts today.

Thunder Megaphone – A Glacial Valley Can Focus and Amplify Thunder Into a Most Extraordinary Sound

We’ve all heard thunder, and we all know what causes it. Many of us have heard two distinct kinds of thunder, but perhaps we never really noticed or thought about it. Recently, I heard a third kind of thunder.

“Ordinary” thunder – a thoroughly extraordinary sound, but the kind of thunder we hear most often – happens when lightning occurs at some distance from the observer. The initial sound of the lightning bolt echoes off surrounding objects and air masses. Because it is echoed so many times, the thunder stretches out into many, many seconds, even though the initial sound might have lasted a second or two at most. Moreover, because the initial sound echoes off soft things with indistinct surfaces – clouds, thermoclines, and weather fronts – and because many echoes reach the ears of the observer at different times, the original sound is greatly distorted. Almost all high frequency components are filtered out, and the observer hears mostly a low-pitched rumble.

When lightning strikes very close to the observer, within a few hundred feet, the sound is entirely different. The observer might not hear echoes of the thunder at all, but only the pure initial sound. It is a single, sharp, intense “POW!” It may be followed by a much quieter, but still loud, whistling or hissing sound.

But what about that third kind of lightning?

I was camping alone in Crawford Notch State Park in northern New Hampshire, when thunderstorms began rolling into the valley just after dinner. I tidied up my campsite just before the rain started, then retreated to my tent. One thunderstorm passed without much incident.

Darkness had fallen by the time the second thunderstorm rolled up from the south. I occupied myself by counting the time interval between lightning and thunder to track the movements of the storms. Fifteen seconds before the thunder rolled up from somewhere west of Mount Bemis, and I knew the storm was just under three miles southwest of me. Seven seconds between the flash and the rumble beyond Frankenstein Cliff, and I knew the storm was passing nearly a mile and a half to my west.

And then it happened!

A flash. I counted eleven seconds. And I heard a sound unlike any thunder I had ever heard before.

The cacophony included at least half a dozen rapid repetitions of the “POW!” of a nearby lightning strike. But at the same time, there was the rumbling and roaring of “ordinary” thunder, but much, much louder than usual.

Before I could figure out what that sound was, there was another flash somewhere to the north. Again I counted eleven seconds, and again I heard that utterly incredible crackling and powing and rumbling and roaring.

This time, I figured it out.

It was a lightning strike right within the upper reaches of Crawford Notch just a couple of miles north of me. It was right within a gigantic stone megaphone formed by Webster Cliff on the east, Mount Field and Mount Willey on the west, and the old glacial cirque of Mount Willard for a backstop on the north.

And this 1,500 foot deep, three-mile-long granite megaphone was pointed right at Dry River Campground.

Yes, the beautiful U-shaped glacial valley of Crawford Notch is a nearly perfect megaphone, albeit open on top. The bare stone faces of Mount Willard and Webster Cliff echoed the initial “POW!” of the thunder almost undistorted. The western slope of the notch is a bit more heavily wooded, but there’s enough bare ledge and rockslide there to provide a pretty good echo. The open top of the notch was covered by the underbelly of the thunderstorm itself, which provided enough of a soft echoic surface to create the usual rumbling of thunder in addition to the clean “POW!” echoes off the rock faces.

But all of this sound was extraordinarily loud because of the megaphone that focused it all right on me and my campsite.

After I got this all figured out, there was a third lightning flash in the north. Yes, eleven second later, there was that glorious, unearthly sound again.

I wondered why I had never heard this kind of thunder before. I have probably experienced thunderstorms in Crawford Notch at least a dozen times over the years, but never heard the Thunder Megaphone.

My best guess is that I probably have heard it before, but never noticed it. Most of the times I’ve camped there, it was with a crowd of friends and family. Much goes on when a thunderstorm rolls in. Ponchos have to be broken out and put on, while at the same time, various disorderly what-nots need to get stashed into cars and tents before they get soaked. There is a bit of yelling and shouting to be done, and paradoxically among the mayhem, kids and dogs need to have their fears calmed. Meanwhile, tarps over the tents and picnic tables are flapping in the gales, making a poor imitation of thunder themselves.

In all my 25 years camping in Crawford Notch, this may have been the first time I experienced a thunderstorm while I was camping there alone. There was no tarp over the tent, and I had anticipated the thunderstorm well enough to get everything into the car long before the rain started.

So, when the lightning and thunder came, I had nothing to do but observe.

What a treat!

I half hope we get a thunderstorm the next time we go camping in the mouth of the Thunder Megaphone.
