Brake fluid is a coolant-based substance with additional additives that can be detrimental to certain materials. While it is commonly understood that brake fluid can only soften or craze plastic, it can, in fact, cause cracking in ABS plastics. This is due to the degeneration of plasticizers, which are responsible for the flexibility and strength of the plastic. The result is similar to rapid ageing, with the plastic becoming brittle and susceptible to snapping. Additionally, brake fluid is corrosive to paint and natural rubber. Its high hygroscopicity, or ability to absorb water, can also lead to corrosion in steel brake lines.

It can also soften plastic
Brake fluid can have detrimental effects on certain plastics, especially ABS plastic. ABS stands for acrylonitrile butadiene styrene, and it is a type of plastic commonly used in automotive applications due to its strength and impact resistance. However, when ABS plastic comes into contact with brake fluid, it can undergo a process called catalytic embrittlement, which causes the plastic to become brittle and crack.
This effect is a result of the brake fluid's interaction with the "'plasticisers' in the ABS material. Plasticisers are additives that give plastics their flexibility and elasticity. They are crucial in providing strength to the material. When brake fluid comes into contact with ABS plastic, it causes degeneration in these plasticisers, resulting in a sudden, rapid ageing process. The plastic loses its flexibility and becomes susceptible to breakage, even from slight movements or engine vibrations.
It is important to note that not all types of brake fluids have the same effect on ABS plastic. DOT3 brake fluid, for example, is specifically designed to be compatible with ABS systems and should not cause damage to the plastic components. Instead, DOT3 brake fluid is only detrimental to natural rubber and paint, and its main concern is its ability to absorb water, which can lead to rust and corrosion in steel brake lines.
However, other types of brake fluids, such as silicone-based DOT 5, can cause issues in ABS brakes. The compressibility of silicone fluid can make ABS calibrated for glycol ineffective or dangerous, and it can also wear on the piston/mechanism. Therefore, it is essential to use the correct type of brake fluid recommended by the vehicle manufacturer to avoid any potential issues.
In some cases, the damage caused by brake fluid to plastics may be mitigated through polishing or replacement of the affected parts. However, it is always best to exercise caution and avoid spillage or contact between brake fluid and plastic components to prevent damage and ensure the proper functioning of the vehicle.

It's unsafe on ABS plastic
While some sources claim that brake fluid should not affect ABS plastic, others state that it is indeed unsafe and can cause cracking. This discrepancy may be due to different types of brake fluids and plastics involved, as well as varying degrees of exposure and temperature conditions.
Brake fluid can cause catalytic embrittlement in ABS plastic, leading to sudden and rapid ageing. This occurs due to the degeneration of "plasticisers," the components that provide flexibility, elasticity, and strength to the plastic. As a result, the plastic becomes brittle and susceptible to snapping with even slight movement or engine vibration.
The impact of brake fluid on ABS plastic can be observed in various automotive applications, such as headlights, windscreens, and instrument panels, and bodywork. In one instance, a rider noticed that brake fluid had completely ruined their headlight, causing confusion as to why this occurred.
While some suggest that brake fluid should not cause such extensive damage, others share similar experiences of cracked and brittle plastic components after exposure to brake fluid. The consensus is that, even after wiping off the fluid, the molecular structure of the ABS plastic has already been altered, rendering it vulnerable to sudden breakage.
To mitigate the potential harm, immediate action is crucial. Absorbent materials should be used to wipe off as much fluid as possible, followed by rinsing with water and scrubbing. However, it is challenging to avoid spreading the fluid around and pushing it further into the plastic. As a preventive measure, some riders suggest changing to silicone brake fluid to eliminate concerns about damage to ABS plastic.

It causes degeneration in plasticisers
Brake fluid is a hydraulic fluid that plays a crucial role in the braking system of vehicles. It is responsible for transmitting the force created when the brake pedal is depressed to the brake callipers, which then apply pressure to the brake pads, causing the vehicle to slow down or stop. While brake fluid is essential for the functioning of brakes, it can also have detrimental effects on certain types of materials, including plastic. One of the main components of plastic that is susceptible to brake fluid is plasticizers.
Plasticizers are chemical additives that are incorporated into plastics to increase their flexibility, durability, and range of functionality. They work by reducing the intermolecular forces between polymer chains, making the plastic more mobile and easier to process. Over time, exposure to brake fluid can lead to the degeneration of these plasticizers, resulting in negative consequences for the plastic material. This degeneration occurs because brake fluid can act as a solvent, dissolving and breaking down the plasticizers within the plastic material.
The effect of brake fluid on plasticizers can vary depending on the type of plastic and the specific composition of the brake fluid. However, in general, the presence of brake fluid can cause the plastic to become brittle and prone to cracking or breaking. This is because the loss of plasticizers reduces the flexibility and impact resistance of the plastic material. Additionally, exposure to brake fluid can also lead to changes in the surface appearance of the plastic, including discoloration, clouding, or a sticky or tacky feel.
The rate at which degeneration occurs depends on various factors, including the type of plastic, the concentration and type of brake fluid, and the exposure time and temperature conditions. Certain types of plastics, such as polycarbonate and ABS (Acrylonitrile Butadiene Styrene), are more susceptible to degradation from brake fluid than others. The composition of brake fluid also plays a role, with some types of brake fluid being more aggressive and causing faster degeneration.
To mitigate the detrimental effects of brake fluid on plasticizers, it is important to take preventive measures. This includes proper handling and disposal of brake fluid, as well as using compatible materials that are resistant to degradation. Regular maintenance and inspection of brake systems can help identify potential leaks or spills that may come into contact with plastic components. Additionally, the use of protective coatings or barriers can also help to shield plastic surfaces from direct exposure to brake fluid.
Overall, understanding the effects of brake fluid on plasticizers is crucial to ensuring the integrity and functionality of plastic components, especially in applications where brake fluid may be present. By recognizing the potential for degeneration, appropriate measures can be taken to safeguard plastic materials and maintain their performance and longevity.

It's important to keep it off your skin
While there are conflicting opinions on the effects of brake fluid on plastic, it is important to keep it off your skin. Brake fluid is very harmful to the skin and can cause serious damage. It is a powerful corrosive substance that can cause severe irritation and burns. In addition, it is highly hygroscopic, meaning it absorbs water, which can lead to rust or corrosion on the skin. Therefore, it is crucial to take precautions when handling brake fluid to avoid any contact with the skin.
When working with brake fluid, it is important to wear protective gear, such as gloves and long sleeves, to minimize direct skin contact. If you accidentally come into contact with brake fluid, immediate action should be taken. First, remove any contaminated clothing and jewellery to prevent further exposure. Then, flush the affected area with large amounts of water for at least 15 minutes. This helps dilute and remove the brake fluid from the skin. Avoid using soap or other cleaning agents during this initial rinsing process as they may interact with the brake fluid and cause further irritation.
If irritation, redness, or burning sensations persist after rinsing, seek medical attention immediately. Have the product label or ingredients list ready to help medical professionals identify the specific type of brake fluid involved. Additionally, keep the affected skin area uncovered and avoid applying any creams or ointments unless advised by a medical professional.
It is worth noting that different types of brake fluids may have varying levels of toxicity and skin irritation potential. For example, silicone-based brake fluids may cause fewer skin issues compared to other types. However, it is always advisable to prioritize skin protection and treat any accidental exposure with caution. Remember, your skin's health and safety are paramount.
