Braking System Maintenance

Why are brakes important?

The brake system of your vehicle is by far the most important safety system that it has. Being able to slow down or stop at a moments notice will help to avoid an incident or accident. Improperly working brakes will not do the job they are designed to do and will not be as effective when needed, especially in a panic stop situation.

Brakes should be regularly inspected, we recommend having your trusted repair facility regularly test drive the vehicle to see how the brake system functions. Then also perform an actual visual inspection, measuring pad and shoe thickness, check for even wear of the pads and shoes, check rotors for run out and hot spots, check hardware to make sure it is working properly and that it is adjusted properly. Make sure the wheel cylinders, brake lines and brake master cylinder are not leaking, inspect calipers for wear, free movement and fluid leaks, and check the level and condition of the brake fluid. Inspect for proper routing and placement of the brake and anti-lock brake sensors.

All of these components need to be in good shape and working properly for the vehicle to have 100% brake system effectiveness while driving. For instance, something that seems simple is the brake fluid, it can get contaminated over time with absorption of moisture and copper, this can decrease the effectiveness of the hydraulics within your brake system causing a less responsive brake pedal to the touch or feel, therefore causing a slight delay or reduction in braking power.

How does the brake system on your car work?

When you press your brake pedal, you engage a complex system. Here’s how it works: the applying of the brake pedal forces brake fluid to engage systems that force the brake pad onto the brake disc rotor, causing friction and bringing your car to a stop. The brake pads of your car are fitted to the brake caliper, this is the part of the car that applies and releases the brake pads from the disc rotor.

Brake calipers comprise the brake caliper housing, inside this housing is a piston or pistons (depending on your car) that push or release when the brake pedal is pressed or released. Specifically designed rubber components ensure that the brake (hydraulic) fluid does not leak from the system or allow dirt and grime into the system.

Maintenance of the braking system:

  • Verify whenever possible the power of braking of each of the four wheels with a brake meter/brake tester. Don’t forget to check the effectiveness of the circuit.
  • Keep the indicated level of brake fluid. Check it often, and replace every two years or 50,000 miles.
  • Be sure to review each time the status of brake pads. Their average life is 25.000 km, but can become blunt before its hardness and lifestyle.
  • You must change the brake shoe (or a shoe or a brake block) for every four changes of brake pads or so.
  • Check to see their headlights and brake lights are working. Also, he urges people to make sure to aim the headlights properly.
  • Do not modify the original brake system. Observe the times given by the manufacturer.

Symptoms that something goes wrong:

  • If your car may be slowing somewhat because it is little brake fluid, because the pads are worn (in which case you hear a chirping) or because the discs are worn.
  • If you brake hard you might have a problem with the servo brake.
  • If the car slows down and loses liquid badly it is possible that the brake pump is in poor condition.
  • If the car tends to stop the “tilted” check the pressure, the wear and alignment of the tires. If these are kept in proper condition, which can brake discs are badly located or that the brake adjustment is uneven.
  • Also it can happen that one has strained greasy between the brake pads and the disc, or a flight of liquid or an excessively soft damping.
  • If you notice the brake pedal is soft it is possible that air in the circuit has been introduced or that the brake liquid is little.

How to Prevent:

With conventional brakes

Do not make “hard braking.” In order to restrain of suitable form exert the same pressure on the pedal without getting to the bottom to prevent the wheels are blocked. If this happens, lift a little pressure on the brake pedal to feel that the wheels spin, and then gently press.

With ABS

  • The ABS (Anti-Lock Braking System) is a braking system that allows that when stops the wheels not they block, and therefore they continue turning, which allows that they obey to the turn that is marked to him from the steering wheel.
  • The right way to stop a car equipped with ABS brakes is to hit the brakes and did not release pressure until the vehicle is stopped. During braking and subject to activate the ABS, will be felt a vibration in the pedal. This effect is normal , Is the way the car to tell us that the ABS is working.
  • It only acts when stepping on the brake with force.
  • To obtain an effective braking system must step on the brake pedal with the force from the outset, while stepping on the clutch. In performing this maneuver will cause the car responds to its maneuverability and achieved its arrest in a shorter space.

How do I know that the ABS on my car is running?

Just start the car, turn on a light og ABS signal. The light should turn off after a few seconds. If the ABS does not shut down, it means that the ABS do not work. Still you can stop the car, but do not have the help of ABS. It would be advisable to bring a workshop to review.

With the change:

  • Use the gearbox to slow it is a maneuver can be very useful in prolonged reductions, as they can be the mountain ports.
  • Never slow down with clutch into neutral to save fuel.
  • Before cutting a shorter running the vehicle must have diminished his speed, since otherwise when it loosens the clutch engine can be passed speed.
  • The revision of the brakes must be released once a year of obligatory way like minimum
