You can make your brakes last a long time or you can wear them out quickly. The choice is yours. Done judiciously, the following money-saving driving techniques won’t clog traffic and few other drivers will notice.
If your brakes wear rapidly and these tips don’t help, the problem is with your car, your mechanic, poorly chosen or installed brake parts, or others who drive the car (teenage boy in the house?). The problem could be one of simple geography, if you happen to live in the mountains.
1. Speed Kills.
Stops from high speed are the mortal enemy of brakes. And a little more speed hurts more than you can imagine. Stopping from 65 mph rather than 55 forces the brakes to dissipate about a third more energy. (Warning: scary math formula coming.) The car’s motion is called kinetic energy. It’s calculated by multiplying half the car’s weight by the square of its speed. (For the math-challenged, “the square” means speed is multiplied times itself.) Brakes sacrifice their lives by turning energy into heat. A little less speed means a lot less kinetic energy — and brake material — needs to be transformed into heat. (No more physics, I promise.)
2. No Lefties.
Use only your right foot on the brake pedal. I often see cars cruising at a constant speed — or accelerating away from me — with brake lights either constantly illuminated or glowing like lonely lightning bugs. By braking with only your right foot, you’ll avoid simultaneously pushing both pedals. Also, it’ll be easier to resist unnecessary brake taps: That left foot wants in on the action. A confession: Like a majority of race drivers I sometimes brake with my left foot, but only in short races or during maximum-effort testing. More than one racecar mechanic has installed a panel between clutch and brake pedals in an effort to make the brakes last as long as the race.
3. Be a Coaster.
Coasting is a surprisingly easy way to get rid of a lot of brake-killing speed. During one 24-hour race, a brake failure forced me to drive about 45 minutes without touching the middle pedal. I quickly perfected the art of coasting. If you know you’ll have to stop at the end of a freeway off-ramp, coasting from 70 down to 50 before you brake will significantly reduce brake wear. Time lost will be little or, if cars are queued ahead, none.
4. Memory Factor.
Memorize places where other drivers inappropriately slow down. Examples include hills which come as a shock to people who have been driving that same road for 10 years, and gentle freeway bends that many mistake for hairpin turns. Often, you’ll have to coast down to their pace. Plan ahead and you might be able to change lanes around them. They’ll re-pass you on the next downhill or straightaway, but you will have used less brakes and gas.
5. Look Up and Save.
Look far enough ahead and you’ll be able to correctly time stoplights, notice traffic backing up or see cars slowing on an incline that’s just become visible. Look beyond the next traffic signal; check out the one after that and, in urban situations, the next and the next. To test how far ahead you look, draw a thin line at eye level on your windshield with a dry erase marker. On level roads, keep your focus above that line and use peripheral vision to position the car within your lane. Then erase the line before a cop asks you why it’s there.
6. Don’t Join In.
Many drivers brake just because the guy in front did. And the first driver touched his brake for no good reason. It’ll take a bit of practice to learn to coast when others brake inappropriately, especially if you weren’t looking far enough ahead.
7. Lose Some Weight.
Don’t carry unnecessary stuff. Math majors will point out that this won’t make a big difference unless you’re hauling those barbells you keep forgetting to drop off at Goodwill. However, some aftermarket parts — especially tires and wheels — can add a lot of weight. More significantly, consider vehicle weight before your next purchase. A heavier vehicle is harder on brakes. And tires. And gas.
8. Flush It.
Brake fluid needs to be periodically changed. In mechanic-speak it’s called bleeding and flushing. Renew your brake fluid, especially if you have an older vehicle or one you purchased used. You gain nothing if you save brake material but the insides of the system rot away. Flushing the brake fluid will make the internal components last longer and the brakes work better. Brake fluid naturally attracts water. In an emergency stop or after repeated brake applications, this moisture boils and severely reduces braking effectiveness. Moisture also promotes internal corrosion, which ruins critical rubber seals. Some vehicle manufacturers recommend renewing brake fluid every couple of years. While some mechanics challenge its cost-effectiveness, brake bleeding is an inexpensive, easy task for a do-it-yourselfer.
9. Upgrade and Specialize.
Don’t complain if bargain brakes wear out quickly, but don’t expect the most expensive pads to last forever. Today’s brake pads are extremely complex. They may contain a dozen or more components, and are designed for specific uses. Brake material that best survives heavy-use, high-heat situations may perform poorly for drivers who emphasize economy. A good mechanic or auto parts store should be able to match your desires with the right brakes.
10. Be Frugal, Not Foolish.
Trying to extend brake life too long will cost big money. If metal touches metal, frugality becomes foolish. A good time to inspect brake material thickness is when you have your tires rotated. Novice do-it-yourselfers: With a wheel removed, it’s easy to check disc brake pad thickness, as they’re open for viewing. It’s more difficult with drum brakes because the drum has to be removed. Other foolishness: downshifting to save brakes. Transmissions (and clutches) cost a lot more than brakes. Race drivers downshift to be in the proper gear to accelerate out of the next turn. If experienced racers are downshifting to reduce speed, their brakes are failing. (With brake failures in racecars, I have found it easier to coast. A mistake on a downshift can cause a rear-drive car to spin out.)
Did you notice that many of these tips will also save gas and make you a safer, smoother driver? I hope so.
