The parking brake cable is the cable that is used to engage the parking brakes on numerous vehicles. It's normally a steel braided cable covered in a protective sheath that's used to activate the vehicle's parking brakes mechanically.
When
stopped or stationary, the parking brake is utilised to keep the vehicle from
rolling. This feature is particularly useful while parking or halting on
inclines or hills, where a car is more likely to roll and cause an accident.
This
is why it is checked during a MOT
testing service, and if it is found to be defective, it will result in
a MOT test failure.
When
the parking brake cable breaks or gets too loose, the car loses this important
safety feature. A bad or failing parking brake cable usually causes a few
indications that warn the driver to a potential problem that needs to be
addressed. If you check MOT
history of your car, an applied handbrake that does not stop the car
from rolling will fail a MOT test.
The
following are four symptoms that your parking/handbrake cable is broken:
1. Parking/handbrake does
not hold the vehicle - A handbrake that does not
effectively hold the vehicle is the most prevalent indicator of a problem
with the parking brake cable. The parking brake cable will lose its ability to
draw the parking brake as tightly if it becomes overly worn or strained. Even
when the parking brake is fully engaged, the parking brake will not be able to
support the weight of the vehicle, causing it to roll or lean. If you
discovered your car previously failed a MOT owing to the handbrake while
conducting an online MOT history check,
a loose cable was most likely the culprit.
2. Parking brake not working
- A parking brake that does not work is another sign of a problem with the
parking brake cable. The parking brake will be disengaged if the cable snaps or
breaks. The parking brake isn't working, and the pedal or lever could be loose.
3. An illuminated handbrake warning
light - This is another indicator of a problem with the parking brake
cable. When the parking brake is set so that the driver does not drive with the
brake applied, the parking brake warning light illuminates. When the Parking
Brake Light illuminates even after the brake handle or pedal has been released,
it could mean that the cable is stuck or jammed, and the brake isn't releasing
properly. If you complete a MOT history checker
online for your car, an illuminated warning dashboard light is a common reason for
a MOT test to fail.
4. The handbrake has an
unusual feel to it - When you use the handbrake, you get a sense of how it
works. The handle will effortlessly draw up and down while also providing some
restriction. When you engage or disengage it, it really should lock solidly
into position. The sensation of your handbrake can be impacted by a stretched,
loose, misaligned, or tangled cable. When you move the handle up and down, for
example, it may seem stiffer than usual. It's also possible that the handle is loose
and unsteady. It's possible that you'll have to work harder to get it to turn
on or off.
To
function, your handbrake depends on cabling connections. When you engage this
brake, its wires apply stopping force to your wheels, allowing your car to
remain stationary.
These
cables aren't indestructible. Corrosion, stretching, movement out of position,
and even snapping are all possibilities. While a little issue may cause your
handbrake to become less sensitive than usual, a more significant issue could
cause the entire system to fail.
If
one of your cables fails, the dashboard warning light for your handbrake may
illuminate. This light, on the other hand, could signal a variety of issues
with the system. Your fluid levels, for example, could be low, or you could
have a faulty connection.
Parking/handbrakes
are an important parking and safety device found on nearly all road cars. If
you suspect a problem with your parking/handbrake cable, get your car evaluated
by a competent mechanic to see if it needs to be replaced.
