Even though your car needs all of its systems to function, the brakes are indispensable when it comes to keeping you and other road users safe when you drive. As such, most motorists are aware that they need to provide their braking system with meticulous upkeep, which involves replacing the brake pads once they succumb to wear as well as flushing the brake fluid once it is old or contaminated. However, few people are familiar with the term 'brake bleeding' as an essential maintenance measure. While this maintenance measure is only necessary every few years, it should not be underrated, as it could make the difference between prolonging the lifespan of these auto parts and premature failure. Check out the following guide to brake bleeding to learn more on why you need this service from your mechanic.
What is it?
Over time, your brake line becomes vulnerable to air bubbles for several reasons. Not only can air makes its way into this line when you are driving around with degraded brake pads, but it can also breach the brake line when you slam on the brakes or when you have an undiagnosed leak. The more air accumulating inside the brake line, the less functional it is in facilitating the movement of brake fluid. As a result, you progressively lose your ability to stop the movement in your wheels effectively, and this causes a delay each time you brake. To prevent any unfortunate accidents, it is advisable to seek brake bleeding services, which is a process where a mechanic will eliminate these bubbles, and this restores the functioning of the brake line.
What does the brake bleeding process entail?
The first thing you should know about brake bleeding is that it is not a DIY job. Any mistakes during this process will compromise your brakes, and this can jeopardise your life. Having said that, the brake bleeding process starts with your mechanic unscrewing the brake bleeder screw that is attached to a hose. This hose is connected to the receptacle that carries the brake fluid. To eliminate the bubbles in the hose, your mechanic will press down on the brake pedal, and this directs the bubbles into the fluid receptacle. Once all the air is eliminated, the mechanic screws back the brake bleeder and releases the brake pedal. The same steps will be followed for all the wheels.
How can you tell if you require this service?
There are several symptoms to be wary of that would be indicative of the need for brake bleeding. A few to take note of include diminished resistance from your brake pedal and changes in the way your car comes to a halt.
