What Happens During A Brake Inspection?

Most car owners are aware of the role their brakes play in a vehicle. However, many are unaware of what components make up the braking system and what happens when they take their car in for an inspection. Before getting into what goes on during a brake inspection, it is essential to know what the brake system is made up of. Most BMW’s, especially newer models all utilize four-wheel disc brakes. Disc brakes offer better stopping power and are more reliable. The disc brake system includes brake pads, rotors, calipers, hoses, a master cylinder, and brake booster. The disc brake system is quite simple. When you press the brake pedal the two brake pads that side inside the caliper clamp against the rotor. The firmer you push the pedal, the harder they clasp.

Older model vehicles might be equipped with drum brakes on the rear. Drum brakes work similar to the disc brake system. However, they aren’t as reliable. They have a housing called the drum and use brake shoes that press against the drum to stop the vehicle. Since many cars are now equipped with the disc brake system, we’ll focus on what happens during a disc brake inspection.

Over time the parts of the brake system, specifically the brake pads, will wear down. Brake pads must be changed to prevent premature damage to the rotors or caliper malfunction. Many of the brake pads made today have a wear indicator installed. It alerts drivers that it is time for them to be changed. The wear indicator will make a high pitched squeak noise. Other parts of the brake system can give clues to problems they might have, which makes diagnosing the issue a little easy. For instance, if a caliper sticks it will make a bad burning smell and sometimes produce smoke because of the friction. If the brake pedal isn’t feeling as firm as it once was, this might indicate a lower level of brake fluid that needs to be filled.

Moving on from the master cylinder, its wheels will be taken off to inspect the workings of the disc brake system. It will include the brake pads, rotors, and calipers.

4 Things To Do Before You Get A Brake Repair Service

The braking system of your car is one of the most used methods. It is the system that prevents accidents and will keep you safe. If any part of your braking system isn’t performing the way it should, you will have complications in slowing down or coming to a stop or even holding a halt. If you are noticing that your brakes aren’t working the way they should, it might be time to have brake repair and service performed. But, before you head out to your automotive shop, there are a few things that you can do before taking your vehicle in. If you narrow down what is wrong, you might be able to fix some of the smaller problems.

Check The Brake Fluid

It is a prevalent problem for car owners in regards to the braking system. When the pressure on the brake becomes more spongy and is softer to push in, you might be low on brake fluid. The simple way to check if this is your problem is by looking at the brake fluid reservoir. The reservoir lies on top of the master cylinder. You can usually spot the tank by the cap on them labeled DOT 3 or DOT 4. If it is under the full mark, add just enough to get it at the line. Remember only to add what is recommended and used in your vehicle.

Check For leaks In The Brake Lines

It will require a little bit of maneuvering, and go under the car. If you follow your brake lines all the way to the rear, look for possible damage to the line. Another area to check that is much easier is the connection to the master cylinder. Sometimes the rings inside the master cylinder can become worn and allow for tiny leaks. If you notice fluid here, it could be the potential cause of your car not braking correctly.

Are Your Brake Pads Worn Down

In a disc brake system, the brake pads are what press against the rotors that make your care come to a stop. If your brake pads are overused, they will start to make that annoying grinding sound. The production of sound is from a metal shim within the brake pad. It is your first indication that you will need brake service. If your calipers are not opening and closing the way they should, it can cause your brake pads to be continually contacting the rotor. If this happens, you will need to have brake repair work done on the calipers to get them to open correctly.

Investigate Your Rotors For Warpage

As mentioned your rotors will be what your brake pads clamp to initiate braking. If you were to look at the rotor, you might notice that they might be worn down. Depending on how long you have gone from your last brake pad change, you might have to have these replaced. Uneven wear or warpage will result in a vibration when at speeds over 30mph and coming to a stop.

Conclusion

In conclusion, there are a few items you can look for before taking your car into to get serviced for the braking system. Knowing them will help you to understand what exactly is wrong, and what it will take to fix the problem.
