Understanding Brake Fluid Types and Their Differences

One of the valuable things that I’ve learned from my long-term experience is that despite being underrated, the brake fluid is a vital part of the brake system. Let’s provide you with key information about the brake fluid and its types.

Typically, there are four types of brake fluid. Each has its unique specifications and usages. They include  DOT 3, DOT 4, DOT 5, and DOT 5.1. 

DOT 3 Brake Fluid

• Overview: It’s q glycol-ether based fluid and it’s most used in most of standard passenger vehicles. 
• Boiling Points: Its average dry boiling point is around 205°C and its wet boiling point is around 140°C. Compared to other brake fluids, it has a lower boiling point. 
• Usage: It’s the most convenient choice for daily driving and standard vehicles. It’s said to be reliable for normal driving conditions and environments.
• Considerations: As it absorbs moisture with time there would be a decrease in its efficiency. So regrowth maintenance and timely changes would be helpful and effective.

DOT 4 Brake Fluid

• Overview: It’s also based on glycol-ether but with a raised boiling point because of its additives. 
• Boiling Points: Its boiling point is higher than DOT 3. The dry boiling point is 230°C and the wet one is 155°C. 
• Usage: It’s a good choice for vehicles with demanding brake requirements. Like vehicles in hilly areas. It’s also used in cars with ABS. 
• Considerations: Just like the DOT 3, it requires regular maintenance and changes. Although it’s more resistant to moisture in comparison with DOT 3, it needs your attention. 

DOT 5 Brake Fluid

• Overview: It’s a silicon-based brake fluid with several differences from DOT 3 and DOT 4. 
• Boiling Point: It’s non-hygroscopic and doesn’t absorb water. It has a high boiling point. 
• Usage: It’s a good alternative for areas with water absorption concerns and it’s also used in military vehicles or the ones that are not driven frequently. 
• Considerations: It can’t be used in cars with ABS. Aldo, avoid mixing it with DOT 3 and DOT 4 because it damages the system. 

DOT 5.1 Brake Fluid

• Overview: Similar to DOT 3 and DOT 4, it’s glycol-ether-based but with higher performance. 
• Boiling Point: It has a high boiling point. The dry boiling point is 260°C. This measure for wet conditions is around 180°C.
• Usage: It’s compatible with the ABS. It’s used in vehicles either demanding driving conditions, heavy tasks, and high brake requirements. 
• Considerations: Despite being high-performance, it’s hygroscopic and absorbs water. So you should be attentive to regular maintenance and frequent brake fluid changes.

There are different types of brake fluid because there are various types of vehicles and each has specific requirements. Each brake fluid suits its suitable type of vehicle. To have an efficient brake system and warrantied safety, choose your brake fluid according to your manual or a reliable mechanic’s suggestion.

Cost Analysis of Brake Fluid Change

Analyzing the cost of brake fluid change is quite a daunting task and requires precision and knowledge. Because it’s not just about the cost of brake fluid itself, many factors should be considered in the final bill. I’m going to share what I know about this topic with you to help you make an efficient and cost-effective decision.  The cost depends on the fluid type, the labor, and even the region and mechanic that you choose. 

All the fluid types don’t have similar prices. Each brake fluid type of DOT 3, DOT 4, DOT 5, and DOT 5.1 require a different amount of money. The DOT 3 and DOT 4 are more cost-effective.

They are used in most passenger vehicles and you can find them in repair shops. However, if you’re going for DOT 5 and DOT 5.1 you should know that due to their specific formulation and high performance, they’re more expensive. Moreover, it isn’t just about fluid type. The amount of fluid that you use is a game changer that depends on your vehicle’s model. 

Now that you know the effective factors on price, it’s time to talk about actual numbers. For a brake fluid change, you should pay something between  $70 to $150. This amount is for a driver who goes for professional service.

But if you have a bit of greasy hands and are familiar with mechanical systems, you can go for DIY. In this consignor, you just need to pay for quality brake fluid which is somewhere between $10 to $40. In the case of choosing DIY, consider your time wasting and also the risk of doing the task incorrectly. 

Despite being more expensive, professional service gives you peace of mind and ensures your safety as they have sufficient expertise in this task. A mechanic can warranty your safety on the road as he has changed the brake fluid correctly.

Depending on which service provider and in which area you choose, it adds around $30 to $110 to your bill.

Briefly, the cost of brake fluid changing depends on the fluid type, the required amount, and the service provider you choose. In years of my experience in Phoenix Car Mag, I realized that in tasks like brake fluid change, you shouldn’t consider the cost too much and it had a direct effect on your safety and vehicle’s longevity and performance. 

Signs That Indicate a Brake Fluid Change is Necessary

According to my long-term experience under car hoods, I can address some telltale signs of vehicles’ immediate need for brake fluid change. You should know these symptoms to not only ensure your safety but also increase your vehicle’s longevity. The signs and symptoms are listed below:

• Soft or Spongy Brake Pedal: When pressing the brake pedal you should get a firm feeling but if it’s like pressing a marshmallow, it’s time to go for brake fluid change. This sponginess shows the air in the brake line due to the degrading and ineffectiveness of the brake fluid.
• Strange Noises When Braking: Squeaking or grinding noises while braking are indicators of brake fluid contamination. It leads to an efficiency drop in brake pads.
• Reduced Braking Performance: The brake fluid is there to transmit force immediately to stop the car. If it’s degraded, it takes longer for the vehicle to stop and you feel less responsiveness. Your brake fluid needs immediate attention. 
• ABS Light Comes On: The ABS warning light on a dashboard is the most attention-taking sign. It’s telling you that low-quality brake fluid is affecting the whole brake system. 

• Visual Check Shows Dark or Dirty Fluid: Consider checking your brake fluid to ensure it’s clear with yellow tins. If it has a dark appearance or floating debris, it means that your fluid is degraded and it’s time to change it. In case of ignorance, it damages other brake system parts.

In my perspective, the vehicle is acting just like us. It’s showing symptoms of problems as same as us that show symptoms of illness. If you ignore your vehicle’s effort to talk to you, you face reduced brake efficiency and in severe cases brake failure which is a high risk for your safety.

You should be attentive to regular maintenance and checkups of your vehicle to not only express your safety but also to practice car maintenance. So you won’t lose anything if you pay attention to these factors. Trust me it’s always a better option to prevent rather than fixing.

The Role of Brake Fluid in Overall Vehicle Health

As far as I learned during my long-term experience in the automotive world, especially Phoenix Car Mag the brake fluid’s role in a vehicle’s health should be appreciated. The brake fluid is the circulatory system of your braking mechanism. 

Brake fluid works under the control of hydraulics. The fluid transfers the force of your foot on the brake pedal to the wheels and rotors. This procedure leads to stopping your car. The proper functionality of it depends on your brake fluid performance and health condition. 

As we mentioned before, brake fluid is hygroscopic and it absorbs moisture over time.

This moisture degrades its efficiency and vehicle’s responsiveness. In some cases, it leads to the phenomenon of brake fade. In this phenomenon, brakes won’t function as the brake fluid can’t transfer the high temperature of the brake pedal to the wheels. In this case, you face the car’s long-distance stopping and even complete brake failure. 

The brake fluid condition has a significant impact on the whole brake system’s health condition. Contaminated brake fluid damages various components of the brake system including the master cylinder, calipers, and brake lines.

Keep the brake fluid healthy to ensure your safety and increase your brake system longevity.

Ultimately the brake fluid plays a large role in a car’s health. Consider regular maintenance to keep your vehicle healthy as it’s a key to having a reliable and responsive vehicle. I always stress this factor that being attentive to your brake fluid means taking care of your vehicle and ensuring your safety.
