![]() This absorbed moisture will drastically reduce the boiling point of the fluid. Hence why road car manufacturers recommend changing brake fluid at suggested timed intervals A certain amount of Glycol will absorb a certain amount of moisture within a certain time frame. In fact, it will absorb a tiny amount of water from the moment it has been manufactured and nothing can be done to stop this. ![]() Glycol based brake fluid is hygroscopic meaning it has the ability to mix with water and still perform adequately. However this ingredient is not susceptible to boiling. The key ingredient Glycol Ethylene has high lubrication properties to lubricate the rubber parts. Glycol based brake and clutch fluid is that most commonly used within the motor industry. You can get Poly/Glycol Ethylene and Silicon based. Also leaks and air in the system will result in the pedal travelling to far and loose the pressure you have generated to stop the car.Ī very important thing to keep in mind is when you purchase brake fluid they are not all the same. One of the enemies of brake fluid is heat!! If enough heat is transferred into the fluid and is able to boil the fluid this will result in brake fade. The basic premise is the brake fluid is non compressible thus being able to exert the correct force through the brake lines and to the calipers. This brake fluid is the solid / physical connection delivering the force you exert on the brake pedal to the brake calipers. In case, you haven’t been lucky with your car and need help with assessing paint damage plus a detailed plan for a repaint, your personal car service, we are here to help.Brake Fluids- Glycol & Silicone explained Brake Fluids What's the difference between Glycol and Silicone based brake fluids?īrake fluid is the precious fluid in a brake system. We hope you never have to find out what the brake fluid does to a car’s paint in practicality and wish we could provide such emergency service for you. If you happen to spill some, do not take your chances and wash it off. However, power steering fluid spilled on the paintwork can make slight blemishes visible on the top layer if left for very long. Unlike brake fluid which extremely detrimental to paintwork, power steering is actually quite forgiving in that it does not show any signs of damage even after few hours of sitting on the paint. They also have different compressibility, boiling points, and lubrication. While both brake and power steering fluids are a type of hydraulic fluid, they differ in their composition. Can Power Steering Fluid Damage Car Paint It can still damage the paintwork of your car and should be wiped off immediately if spilled by any chance. But this does not mean you should completely ignore Antifreeze as a danger and be careless with it. ![]() Older Vehicles, sporting ethylene glycol paint will be stripped off their coat if exposed to antifreeze for more than ten minutes Though modern paint made up of Propylene glycol will have little to no effect in such a short while. It is recommended to get the brake fluid replaced by a qualified mechanic to avoid any such issue.īeing aware of how to avoid brake fluid damage, now let’s understand why the hydraulic fluid of this grade is hostile to paintworks.Īmong all the fluids in a car that can potentially damage its showroom finish, antifreeze is one of the better-tolerated fluids, at least by modern paints. Usually, the spillage occurs after bleeding the brakes when new brake fluid is being poured. Severe paint damage is on the brink if do not carefully perform the replacement. So, if you’re not a victim of brake fluid paint vandalism, this is the place you should be most wary of. Interestingly, this is also the time where brake fluid is most likely to come in contact with your paint, especially if you do it yourself. This is primarily why a fluid replacement is recommended every 30000 miles. ![]() So now you know, the fluid present down beneath can hurt your car’s paintwork, but you might be wondering, how might you come across such a situation knowing the potential harm brake fluid can cause.īrake fluid is a hygroscopic liquid which means it absorbs and accrues moisture from the atmosphere that can potentially lead to corrosion of the metal parts in the braking system.
