Parking Brake: How it Works and Types

Among the various components of a vehicle, there is one that is often overlooked: the parking brake.

The main function of this braking system, also known as the handbrake, is to immobilize the car when parking, especially on slopes.

Find out in this article how it works, how many types of parking brakes there are and what you should do if this braking system isn’t working properly.

 

What is the Difference Between a Foot Brake and a Parking Brake?

Quite simply, the foot brake is the brake that reduces the speed of the vehicle by means of a pedal. A car’s parking brake, on the other hand, is a system that keeps the car stationary.

 

What is the Function of the Parking Brake?

The function of the handbrake is to keep a car stationary while it is stationary.

This function is even more important if the car is parked on very steep climbs or descents, as it prevents the car from sliding freely.

The mechanism of this brake only acts on the rear wheels of the vehicle, bringing them to a standstill as soon as it is applied.

 

When to Use the Handbrake?

You should use the handbrake whenever you park your vehicle to ensure that it remains stationary.

 

 

What Types of Parking Brake?

In short, there are two types of handbrake: manual and electric.

 

Manual Parking Brake

This is the most common type of brake used in cars, usually consisting of a steel cable.

The braking force is transmitted through this cable to the rear wheel brakes.

 

Electric Handbrake

The electric parking brake (or EPB – Electronic Parking Break) is a button that, when activated, relies on the electrical system to immobilize the vehicle.

Although it has less impact on the wear and tear of car parts, it is important to note that this brake only works if the car has a battery.

 

What Handbrake Models Are There?

The car’s handbrake can be:

  • A small lever under the dashboard;
  • A lever between the front seats, behind the gearbox;
  • An extra pedal on the far left of the pedal system;
  • An electric/EPB button.

 

 

How to Apply the Handbrake?

To apply the brake on the manual model, simply pull the lever with a quick, firm gesture. If you have any doubts about whether or not you have applied the brake, check that the handbrake light is on in the instrument panel.

In the case of the electric parking brake, simply pull the switch to activate it automatically. To deactivate either system, simply do the opposite.

 

What Are the Common Parking Brake Problems?

There are several reasons why, for example, the parking brakes doesn’t “lock”.

The main causes include:

  • Cable breakage;
  • Jaw problems;
  • Brake pads breaking;
  • Rust on the tongue or rack.

 

What Are the Signs That Your Car’s Handbrake Needs to be Serviced?

Preventive maintenance is always the best option to avoid extreme situations. However, it is always wise to keep an eye out for possible symptoms of breakdown or wear, such as:

  • The lever rises too high, or you have difficulty lifting it;
  • The car slips even when you apply the handbrake;
  • The parking brake does not lock completely.

In these situations, it is important to correct them as soon as possible, as your safety and that of other drivers could be compromised.

 

The Handbrake Won’t Lock: What Now?

If you notice that the parking brake isn’t “locking up”, you should get this sorted out by a car repair shop as soon as possible.

 

What Care Should You Take With Your Parking Brake?

To extend the service life of this component, you should pay attention to certain aspects, such as:

  • Carry out check-ups every 10 or 15 thousand kilometers;
  • Avoid pulling too hard on the parking brake, even in steep parking lots;
  • Lubricate the parking brake mechanism regularly to ensure smooth operation and prevent corrosion;
  • Make sure that the parking brake is fully disengaged when you start reversing. To confirm this, check the lights on the dashboard.

If your car has been sitting for a long time, visit your trusted mechanic before you start driving for preventive maintenance.
