Can You Put Wd 40 On Brakes

Having squeaky brakes can be quite annoying for many people. They would wish there was something they could do to make it stop. That is why some might consider spraying WD40 on the brakes to see if they can be quiet, considering it is a lubricant.

Is it a good idea to have WD40 sprayed on the brakes?

WD40 should not be sprayed on the brakes to reduce the squeaky noises. This is because WD40 will reduce the friction between the brake pads and the rotors. This would mean the brakes do not work as well as they should. Also, WD40 is just a temporary solution.

As you can see, it is vital to find a lasting solution that will help keep the brake noise to a minimum.

Dangers of Spraying WD40 on the Brakes

WD40 has been a great lubricant on the shelves for a long time. People would easily buy the lubricant because it is also easily available. However, we would not advise you to use it on brakes. Here are the top reasons why WD40 is not good for your brakes.

  1. The car can fail to stop on time

WD40 is a solvent, meaning its main job is to dissolve rust. That is why you may find people using WD40 to dissolve rust on the brake rotors. However, doing so would make the rotors not function properly. There will be a reduction in friction, which is important for stopping the vehicles.

  1. Calipers may corrode from WD40

We all know that WD40 is meant to dissolve rust, but this time around, it can cause damage to the caliper, dust boot, and piston seals, thus exposing them to the elements. Once they are exposed, the result is that they can rust over time.

Other than corroding, expect leaks too. If the piston seals are broken, then you can start losing the brake fluid, which is equally dangerous for driving the car.

Some people also end up experiencing caliper seizures because the corrosion makes it hard for the calipers to retract after you release the brake pedal.

  1. Destroying the brake pads 

Take note that WD40 is not meant to be a cleaner. As such, you should not always use it to clean the brake pads. You can expect the brake pads to be slippery because of the additional layer brought about by spraying WD40.

Also, the materials used to make the brake pads can break down because of spraying WD40 on them.

All in all, you see that it becomes hard to stop the car because of such a mistake. It is best not to use WD40 on the brakes.

The Best Way to Clean Brakes

The Best Way to Clean Brakes

Now that we have recommended that you cannot use WD40 for cleaning brakes, what is the option?

Your brakes can work for a long time without requiring any cleaning. You can expect some lasting over 65,000 miles without any major repairs.

Rust and corrosion can build up, especially on the hub and rotor. This would need proper cleaning to loosen corrosion and maintain the right contact between the rotors and brake pads for the best stopping performance.

The best option would be to consider the WD40 Specialist Automotive Brake and Parts cleaner. This would be a great product to use for wiping down your brake rotors to remove as much dirt, grime, and other debris to ensure that the brake rotor is clean and does not squeak anymore.

The WD-40 Brakes & Parts cleaner is designed specifically for this purpose. As you can see, it will do a good job of ensuring the brakes are cleaner than before.

This formula is also fast to dry compared to the usual WD40 you are used to, which would take longer to dry, compromising your car’s braking. This product would also dissolve grease, dust, and oil on the parts. Once you are done cleaning the brakes, expect them to be shiny and clean.

Other than using the product on brake rotors, you could also use the same on calipers, brake pads, linings, brake drums, and clutch assemblies.

How to Keep the Brake Rotors Shiny

You might love how the alloy wheels look on your new car. However, it is possible that the brake rotors would end up with rust or dirt on the brake rotors that would taint the looks of your wheels.

This would be something that would make people wonder how to keep the rotors shiny.

It can be hard to keep the rotors from rusting because they are mostly made of cast iron which is susceptible to rusting. One way of preventing rust is to drive the car more often. The friction will help clear the rust that would have started to form.

The other option would be to use the WD40 Brakes and Parts cleaner. It would help to keep the brakes looking shiny for a long time.

What can you use for cleaning brake pads?

Besides the WD-40 Brakes and Parts Cleaner, you can use dish soap and hot water to clean the brake pads. This is only if they have not been soaked in oil, or else it becomes hard to clean the oil off the brake pads.

Will the brake pads be destroyed if sprayed with WD-40?

WD-40 being a light lubricant, might make the brake pads absorb some of it, but it would not be too bad. If you can give them a good wash using the right brake cleaner, then they would be good to use once again.

What would WD-40 also not fix?

As much as it is a lubricant, the WD-40 would not fix bike chains, door hinges, gears, musical instruments, firearms, and more. Always use the right type of cleaner for the different parts to ensure you have the right outcome.
