Engine oil gives life to our vehicle. It reaches every corner of the engine to make sure the parts move smoothly while preventing friction and noises.
Then again, using the right kind of oil can make or brake (pun intended) our driving experience. Pick a low-quality product and it’ll fail to keep the engine lubricated. But what about other sections? The interior of vehicle has different components apart from the engine. One of them is the brake system. So, does engine oil affect brakes too?
Engine oil contains hydrocarbon that can make rubber seals in the brake system deform causing damage to it. That’s why there are hydraulic fluids that just work individually to help stop the vehicle. Neither we should use engine oil interchangeably nor mix it with the fluid.
What's Inside:
Role Of Engine Oil In Brake’s Performance
So, how engine oil affects brakes? Vehicle brakes comprise several rubber seals which don’t go well with engine oil. It’s because such oils contain hydrocarbon distillates that can cause gasket materials to deform or swell, according to the studies. As a result, it can make the brake system leak, stick, or fail. In case that happens, you have to replace all the parts containing rubbers.
To avoid this, we should make sure the oil doesn’t get into such parts of the vehicle. Plus, it’s a must that we use fluids designed for individual purposes and avoid mixing or interchanging varieties. When it comes to the brake system, we should always opt for brake fluids.
Brake Fluids Vs. Engine Oil
What makes brake fluids different from engine oil? Brake fluid is a kind of hydraulic fluid whereas engine oil is a hydrocarbon lubricant.
The fluid contains a mix of 75 to 90% of glycol ether or silicone, 5 to 20% lubricant base, and some additives. While the base ensures the moving parts of the circuit work smoothly, additives help protect the circuitry against oxidization. The main function of such fluid is to transfer power to brakes. As our foot presses down on the pedal, the fluid translates the force into pressure and sends the latter to the brake system causing the vehicle to stop.
Contrariwise, motor oil works as a lubricant. It has up to 90% of hydrocarbon distillates and anti-knocking agents such as copper, cerium, and lead. These metals help make the oil more viscous. So, whenever we add oil to our car engine, it moves across different paths, reaches every nook and cranny of the metallic component, and lubricates them. As a result, it helps avoid friction among the parts around engine piston and makes sure they move smoothly.
How To Improve Brake Performance
- High-Quality Brake Pads
Using wrong kind of brake pads can affect the brake. Hence, settle on an option depending on the type and condition of your vehicle, style of driving, and purpose. If it’s for commuting, then opt for a sturdy ceramic brake pad. In case you have a sports car, then it’s better to pick solid semi-metallic pads since they can handle hot bites well.
- Fresh Brake Fluids
If brake fluids haven’t been changed for more than 2 years, it can cause braking issues. However, such fluids can degrade sooner based on environmental factors like humidity or driving patterns. So, changing the fluid on time and using fresh one is also important to improve the performance.
- A Solid Set Of Rotors
Choose a set of high-quality rotors to ensure braking performance. In case you have high-performing vehicles, then opt for a 2-piece cast iron rotor.
Frequently Asked Questions
Can Low Brake Fluid Cause Brakes To Grind?
Yes, low brake fluids can cause the system to make noise. When the reservoir doesn’t have enough hydraulic fluid, the pedals can’t depress the pads effectively. This results in damage to the pads and causes grinding, squealing, and/or squeaking noise as you use the brakes.
Hence, use fresh fluids as you notice the signs. Some of them include illumination of brake warning light, spongy feel of brake pedals, longer braking duration, and change of fluid color.
Does Low Oil Level Affect Driving?
Yes, low level of engine oil affects driving since it won’t keep the engine system enough lubricated. Consequently, there will be friction caused among the moving parts that will lead to severe wear of the engine. If the system starts to get damaged, it’ll affect the handling ability of your vehicle.
Final Words
Motor oil is actually important to the engine system rather than brake system. For the latter, special brake fluids have been designed that work to stop the vehicle. Hence, using the right kind of fluid is important. Check the vehicle manual or master cylinder reservoir cap to see which option is suggested.
While DOT3 and DOT4 are glycol-based and absorb water, DOT5 is made of silicon. Plus, we suggest replacing them periodically. When the fluid is low or degraded, the boiling point will be lower which can damage the entire brake system decreasing its efficiency. And this is what happens if you don’t change brake fluid.
