Most of us have a can of WD40 in the garage. We’ve all used it to lubricate creaky doors or weaken tough rust.
But could WD40 help with car maintenance, too? Many people wonder if they can use WD- 40 on their brakes after all, brakes are one of the most important parts of your vehicle and taking good care of them is essential.
Read on to find out more about how using WD40 might affect your brake system and how you should maintain them properly for safe driving.
What is WD40?
WD40 is a household name that many people reach for when they need a quick fix to a problem. Unfortunately, when it comes to brakes, WD40 is not the solution you should be using.
While it may seem like a simple solution, spraying WD40 on your brakes can actually make the problem worse.
The oil in WD40 can cause your brakes to slip and slide, leading to longer stopping distances and an increased risk of accidents. In fact, using WD40 on your brakes can even lead to complete brake failure in extreme cases.
It’s important to remember that not every problem has a quick fix, and reaching for WD40 may do more harm than good when it comes to your brakes.
Can I put WD40 on my brakes?
If you’re asking yourself whether or not you can put WD40 on your brakes, the answer is No.
While WD40 is a fantastic all-purpose lubricant and can be used for a variety of applications, it is not suitable for use on brakes.
This is because WD40 is not designed to withstand the high temperatures and pressure that occur during braking.
In fact, using WD40 on your brakes can actually be dangerous as it can cause the brakes to become slippery or even fail completely.
Instead, stick to using brake-specific lubricants and cleaners to ensure your brakes stay in top condition and keep you safe on the road.
What happens if you put wd40 on your brakes?
One common mistake car owners make is using WD-40 on their brakes to stop squeaking. But what happens when you put WD-40 on your brakes? Let’s explore the potential effects of this common DIY fix.
Loss of Braking Power
The first effect of putting WD-40 on your brakes is a loss of braking power. WD-40 is a lubricant, and braking systems need friction to slow the car down.
By coating the brake pads with WD-40, you’re effectively reducing that friction.
This can lead to a longer stopping distance, which can be dangerous in emergency situations.
Reduced Brake Pad Lifespan
Another effect of putting WD-40 on your brakes is a reduced lifespan for your brake pads.
WD-40 can cause brake pads to glaze over, which means they become shiny and slick.
This reduces the pad’s ability to grip the rotor and slows down the car. It also means that they will need to be replaced sooner than if they were properly maintained.
Increased Risk of Accidents
Putting WD-40 on your brakes can also increase the risk of accidents.
As mentioned, a loss of braking power and reduced brake pad lifespan can impact a car’s ability to stop.
This means that you could be at a greater risk of rear-end collisions or hitting pedestrians if you’re unable to brake in time.
Potential Damage to Brake Components
Lastly, using WD-40 on your brakes can potentially damage other brake components.
The lubricant can get into the porous surface of the brake rotor and contaminate the system. This can damage brake hoses, seals, and calipers.
In extreme cases, it could lead to brake failure, which is something you definitely don’t want to experience while driving.
Conclusion
To conclude, no, WD40 should not be used to lubricate brakes because it could cause damage by affecting the metal, causing rust.
Even though WD40 is a great product for preventing corrosion and cleaning metal parts, using it on your brakes would put you in danger and the risk is just not worth it.
Brakes are one of the most important components in any car or bicycle so please do yourself a favor and get quality products specifically designed for brake maintenance.
