Braking News: Keep Your Stopping Power

Richard Petty once told AutoNetTV, “You’ve gotta have good brakes. If you’ve got good brakes you can keep yourself out of a lotta trouble.”

That’s why a regular brake inspection is on every St. Peter car’s maintenance schedule. An inspection at Autotronics of ST Peter will check your brake system and let you know if there are any problems.

Of course, if you’re having trouble with your brakes, get your car into Autotronics of ST Peter right away. Here are some symptoms to watch for:

  • Low or spongy brake pedal
  • Hard brake pedal
  • A brake warning light that stays on
  • Constantly squealing or grinding brakes
  • Vibrations or clunking sounds when you apply your brakes

If you are experiencing any of these, it’s time to get your brakes checked.

There are two types of brakes: disc and drum. Disc brakes have a rotor that’s attached to the axle. Calipers straddle the rotor, kind of like the brakes on a bicycle.

Drum brakes are more common on back wheels. Both types have pads or shoes that press against the brakes and slow the vehicle. Brake pads and shoes are made out of very tough material to withstand the heat and force generated when stopping your car. Eventually, they wear out with use, and become too thin and need to be replaced.

If the brake pads wear away completely, you can damage the rotors. The calipers can grind grooves in the rotor. Then the rotor must either be resurfaced or replaced. That’s not only expensive, but also dangerous because your vehicle won’t stop as quickly. Sometimes rotors warp or crack and must be replaced.

Brake service will also include a check of your brake fluid. When the brakes are applied, the pressure in the fluid actives the brake pads or shoes. Not enough fluid means not enough pressure to brake properly. Also, water builds up in the brake fluid over time, which leads to corrosion, leaks and brake damage, and with hard use, the brakes could severely fade or even fail. You should change the brake fluid when your manufacturer recommends to avoid these problems.

There are different grades of brake pads; good, better and best. Higher grades cost more, but give better braking performance and smoother operation. It’s OK to upgrade your brake pads. But, never use a grade that’s lower than what the manufacturer recommends.

So, be sure to properly maintain your brakes, because it’s a lot cheaper than paying the body shop after an accident.

Come in to Autotronics of ST Peter for an brake inspection before damage occurs. You can call ahead for an appointment by calling 507.934.9290.

Autotronics of ST Peter Radiator Service

The coolant system is a vital part of your vehicle. It is also the second most common cause for vehicle failures. Even though coolant system failure is fairly common in St. Peter, it is easy to prevent.

The most recognizable part of the coolant system to Cleveland auto owners is the radiator. It is connected to the engine with hoses and is filled with coolant. The coolant draws heat off the engine and then passes into the radiator. Air passes through cooling fins to reduce the temperature of the coolant and then it’s back to the engine again.

There are several ways for the cooling system failure. Most common is with the coolant itself. Coolant is comprised of water and antifreeze. The proper ratio keeps the coolant from either boiling away or freezing. Understandably, either can lead to massive engine damage.

Another vital coolant issue that is often overlooked by St. Peter drivers is the age of the coolant itself. Antifreeze has additives that protect the coolant system from corrosion. As these additives are depleted over time, they can’t protect the radiator and other parts from rust, scaling and corrosion. That old container of coolant gathering dust in your garage may still keep your engine cool, but it won’t protect it from corrosion.

If get a warning message to check the coolant or if the minivan temperature gauge is in the hot zone, your cooling system needs to be checked. It’s OK to add water or antifreeze yourself. But you need to be cautious. Remember four things:

  • First, you never want to open the radiator pressure cap. You could be severely burned.
  • Second, get to Autotronics of ST Peter in St. Peter immediately if your coolant is low. If that is not possible, follow the directions in your minivan owners manual – it will direct you to only make additions to the coolant overflow bottle.
  • Third, remember that you need a proper mixture of water and antifreeze. If you make an emergency addition to your cooling system, follow-up with your Autotronics of ST Peter service center where we can make necessary adjustments.
  • Fourth, not all cars use the same type of antifreeze. You need to check your minivan owners manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. Again, another reason to depend on your Autotronics of ST Peter service center in St. Peter to do things right.

Remember, your St. Peter service center has the equipment to change your coolant quickly and inexpensively.

Differential Service At Autotronics of ST Peter

Here at AutoNetTV, we have national viewers, like your neighbors in St. Peter, who write to us with questions or feedback. One common question we’re asked is: “What is a differential and what does it do?” You may have been told by your Autotronics of ST Peter technician that your differential needs service, or seen it as an option up on the service menu. Differential service at Autotronics of ST Peter covers a lot of things, so let’s first talk about what a differential does.

As you drive through a turn, your outside wheels and inside wheels turn at different speeds. Kind of like the cars going around a race track – the ones driving in the outside lanes have a greater distance to travel than the cars in the inside lanes. The differential is what allows the outside and inside drive wheels to rotate at slightly different speeds so that the tires don’t hop or skip while taking corners, or lose traction in dirt or snow on Cleveland interstates. Differentials have gears in them that transfer the power from the drive train to your wheels – which is why they’re often referred to as gear boxes. The gears need to be very strong to do this work, and they need to be properly protected so that they’ll last.

All vehicles in St. Peter have some form of differential. If you have a front-wheel drive car, your differential is sometimes called a transaxle and is located in the front. If you have rear-wheel drive, the differential is in the back of the car. St. Peter auto owners with a four-wheel drive vehicle have a differential in the front and the back – and in the middle as well. The center differential adjusts for differences in speed between the front and rear wheels.

Differential fluid lubricates and cools the gears. Over time, the fluid can get dirty from bits of the gears grinding off. The additives that keep the fluid clean and protect the differential break down over time. So your auto manufacturer has scheduled intervals for you to have your differential fluid changed. Talk to your knowledgeable Autotronics of ST Peter service advisor if you are not sure about your recommended schedule.

Differentials are hard working mechanisms, and, along with the gears in a manual transmission, need to be serviced regularly at Autotronics of ST Peter with high-quality, replacement fluid. Your St. Peter service professional can give you more information as to when your next differential service is recommended. You can also ask if they have a record of when the service was last completed.

As with most service intervals, if you are driving under more severe conditions in the Cleveland area, you will want to service your differential more frequently. “Severe service” conditions are  defined in auto makers’ owners’ manuals, and include: frequent starts and stops, short trips, cold MN weather, hot weather and towing. All these factors add to the stress of the vehicle and its parts. Also, off-roading in MN can be especially hard on differentials, especially if you cross streams. Proper service at Autotronics of ST Peter will extend the life of your gears and keep them running more smoothly.
