Brakes really aren’t optional equipment for St. Peter drivers. And taking care of them isn’t optional either.

A regular brake inspection is on every MN car’s maintenance schedule. At Autotronics of ST Peter, our team will check your brake system and let you know if there are any essential problems. Of course, if you’re having trouble with your brakes, get your car into your St. Peter or Kasota service center right away. And watch out for these problems:

• 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

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. Pads, called shoes, push against the inside of the drum to slow the vehicle.

There are several things that need to be serviced on the brake system. First, the brake pads and shoes wear out with use, and become too thin to really help. 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 and that can be expensive. But putting it off is dangerous because your minivan won’t stop as quickly. Sometimes rotors warp or crack and must be replaced.

Brake fluid is also important. When the brakes are applied, the pressure in the fluid activates the brake pads or shoes. Not enough fluid, not enough pressure to brake properly. Also, water builds up in the brake fluid over time, which leads to corrosion, leaks and harmful brake damage, and with hard use, the brakes could severely fade or even fail. St. Peter drivers should change the brake fluid when their automobile manufacturer recommends it.

There are different grades of brake pads sold in the St. Peter area. There are regular, metallic and ceramic – higher grades are more expensive, 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 vehicle manufacturer recommends.

Be sure to properly maintain your brakes because it’s a lot cheaper than paying your nearest Cleveland area body shop after an accident.

Hello St. Peter, let’s talk about brakes. Braking, as all MN auto owners know, is slowing or stopping your vehicle. As you can imagine, brakes are engineered to work well on a particular vehicle application. For example, you would expect more powerful brakes on a heavy-duty pickup that routinely hauls big loads and pulls trailers, than you would on a compact car. And a Corvette that can go over 180 miles per hour would have much different braking needs than the family mini-van you drive around between St. Peter, Cleveland and Saint Peter.

But the mechanical aspects of the brakes themselves are just one issue. There’s also the power brake pump and brake fluid. And then there are the tires, which are critical to the effectiveness of the brakes.

Let’s step back. A new minivan or truck rolls off a local St. Peter showroom floor. It has brand new brakes with brand new brake pads. The brake lines and pump are filled with fresh fluid and are completely clean inside. And the tires are brand new, with full tread. It is ready to go.

Naturally, braking power is at its peak performance. Now the miles start to add up on the minivan. St. Peter motorists tend to focus on the brake pads. In the automotive business, the pads, and shoes on drum brakes, are called the friction material. That’s because they provide the friction used to stop the vehicle. The pads are designed to be effective throughout their useful life – it’s not until they are worn so thin as to be out of vehicle manufacturers’ specs that they lose their ability to stop.

The mechanical parts of the brakes have pistons and springs that get quite a workout while breaking. Over many miles around MN, these wear and get gummed up. They start to lose effectiveness gradually and could even fail – a scary possibility That’s why a regular brake inspection at Autotronics of ST Peter is important for your minivan and your family’s safety. At Autotronics of ST Peter we can test the operation of the brakes and see if any parts need cleaning or replacing.

That leads us to brake fluid service at Autotronics of ST Peter. Some of the critical additives in the fluid that lubricate and clean the minivan fluid system are depleted over time. That and moisture building up in the system reduce the performance of the brake fluid. A brake service at Autotronics of ST Peter cleans out deposits, water and dirt. Then the system is filled up with fresh fluid.

The tires are what connect the minivan to the road. Stopping force all comes down to traction. The better the tires grip the road, the quicker you’ll stop.

This is especially important on wet Cleveland area freeways and surface streets. Studies have shown that wet stopping distance increases significantly as tires wear down. MN car owners need to understand that they can have brakes that are operating at peak efficiency and yet still be in danger because their tires are worn out.

Good brakes are obviously very important. If you’ve ever had your brakes go out while you’re driving around the Cleveland area, you’ll know how terrifying it can be. Today we’ll focus on how to tell when you have a brake problem, and how to make good repair choices.

Often, the first indication that something’s wrong with the brakes is an unusual sound. It could be a squeal, chatter or grinding sound.

Some brake pads have a little piece of metal embedded in them that will make a squeal or chirping sound when the brake pads have been worn down to the point that they need to be replaced. It’s an early warning indicator.

When you hear that sound, schedule an appointment at Autotronics of ST Peter soon.

Now a chattering sound is more urgent. That usually indicates that something is loose. It could be a brake pad or even the brake calipers. If one of those parts falls off, you could have some serious trouble stopping the vehicle. It would be a good idea to park it until you can get into the shop.

A grinding noise usually means that the brake pad is completely worn away and the metal parts of the brake are rubbing directly on the metal brake rotor. That means the rotor is being damaged and will need some work. More on that later.

Another warning sign is that your brake pedal may feel soft and spongy – or it may even feel very hard to push in. Both could mean trouble. And of course, you may get a dashboard brake warning light.

Now when it comes time to replace your brake pads, you have a choice to make. You can get the same pads that came standard on your vehicle. You can expect the same performance and durability as with the pads that came on the car from the factory.

Now you can also get a budget brake pad. Sometimes drivers insist on lower cost pads. That’s OK if the budget demands it, but you need to be aware of the trade offs. Lower grade pads are usually noisier, so you’ll have to live with more noise when you apply the brakes. They also tend to generate a lot more brake dust, you know, that black dust that accumulates on your wheels. And they probably won’t last as long either. In our opinion, that’s a lot of compromise for just a few dollars in savings.

You can also choose to buy premium brakes pads. These perform at higher specifications than the factory pads. You can expect quieter operation, less brake dust and better stopping power.

Now, getting back to the rotors. The rotors are the discs that the brake pads clamp down on to stop the vehicle. If you’ve been driving with completely worn brake pads, you’ve scratched grooves into the rotors. If the grooves aren’t too deep, the rotor can be resurfaced. A thin layer of metal is cut off the surface of the rotor to make it smooth again.

Now, if the grooves are too deep or if the rotor has already be resurfaced before, there may not be enough material to resurface and still have a rotor that’s thick enough to safely stop the vehicle. In that case, the rotor will have to be replaced.

Something that’s often overlooked is the brake fluid. Your manufacturer has a recommended schedule for evacuating the old brake fluid, cleaning the system and refilling it with fresh brake fluid. This is really important to brake performance.

So here’s the bottom line: if you suspect, inspect. If you notice any of these warning signs, have your brakes inspected. Your advisor can help you make the repair decision that’s right for you.
