Many ask us about the failures in the handbrake, and that is a problem that affects many cars today.

The handbrake, they can have two braking systems depending on the system they are riding, we can differentiate the faults, we will detail them below:

Rear drum brake:

The drum brake is a braking system that you use the shoes as a friction system against the drum so that friction produces a brake.

1, Wear on the shoes: the Wear of the shoes is the most recurrent fault, with the passing of the kilometers they wear out and do not get close to the drum. Therefore it does not generate braking.

Solution: changing the shoes and cleaning the system.


2, Drum wear: if the shoes are new, and even then it does not break, it may be that the drum is worn, may have new shoes, but if we do not have a surface to brake, this fails and causes brake failure.

3, The cylinder: a common fault, which we can find, there may be losses of brake fluid; this can wet the shoes and stop braking; another way is that due to lack of pressure, they can not expand the shoe, and therefore They do not stop.

Solution: cleaning and replacement of the complete rear brake kit, the oil will be in the shoe. It is necessary to change them, and we will clean with grease remover and purge the circuit again.

4,  The brake actuation cable, due to the corrosion this stops working, can only be on one wheel or at 2 o’clock, changing the cable, or if the vehicle allows it by re-tensioning it, this will solve it.


With disc brake:

The system is very similar to that of the front wheels. A cylinder pushes the brake pads against a brake disc, with the difference that the parking brake operated with a cable.

The most common failures:

1, Wear on the pads: the pads are responsible for braking the vehicle, you may be able to brake well with the foot brake, but when we have to operate it with the handbrake, it will not hold the vehicle.

2, Wear on the disc: the rear discs also need to be changed; many have worn much higher than recommended, so the solution is to change them to solve this brake failure.

3, Another common failure is the piston: the piston is responsible for exerting force on the pads. If it is in poor condition or even if it is not activated by dirt, in the same, it must be replaced or tried to clean them, not grease should include as more dirt would accumulate, and the fault would reappear faster.


4, Another of the braking failures can be the tensioning cable, this cable takes corrosion and wear, so it is necessary to replace it.

To all this, in both cases it is advisable to change the brake fluid when you send us the vehicle manual, many users forget it, and it is necessary to keep our braking system in good condition and eliminate these failures.

These are the most common failures in the rear braking system of our vehicle; identifying them in time is necessary for safe driving.
