About Brake Fluid

Brake fluid is subjected to meet certain quality standards for the braking system to work properly. Although replacing these fluids is once in a year schedule, but knowing the characteristics is must for an automobile owner. Further readings will let you be familiar with the brake fluids, their purchase, and a few queries as well. So, read on. 

What if you push the brake and your vehicle doesn’t stop? Well, brake’s functionality is directly proportional to the safety of commuters and other entities around. And fluid inside is an integral part of the braking system, speaking of which consists of master and slave cylinders. Whenever you apply brake, master cylinder pushes the piston causing the liquid to flow through the slave cylinders at each wheel. And therefore, the pistons at slave cylinders cause the vehicle to stop. Front vehicles play a significant role in braking mechanism because the force one applied throws the car’s weight forward. For that, different types of brakes experts mount on front and rear end. component of fluid is the same that spread evenly throughout the system. But there are different types involved we are discussing here.  

Types of brake fluid 

There are two chief types of brake fluids – one is glycol-based, and the other is silicone-based. The basic difference between these two is that glycol-based fluid is for vehicles with Anti-lock Brake System (ABS). And, those without ABS is good with silicone-based fluid. In any case, switching the brake fluids is something that compromises with the performance of the braking system. Therefore, experts do not recommend vehicles with glycol-based fluid to switch to silicone-based. Moving further, these fluids are classified by the Department of Transport (DOT) out of which major three types are DOT3, DOT4 brake fluid, and DOT5. Here, we have got you covered if you are looking to buy brake fluid in Dubai and unsure of when to change and how much it will cost. Keep reading further, and you will know. 

Before brake fluid change 

The significant characteristics of brake fluids are viscosity, boiling point, corrosion, and compressibility. And, failure of even one causes the failure of brake system overall. For example, if you test a newly replaced fluid after 12 months, you can see 2 percent of water content, which slowly accelerates the process of corrosion. Excessive water content thereby decreases the boiling water, which further leads to brake system failure. Other than that, water corrodes other brake components as well. So, how often should you change or replace the brake fluids? Well, the answer to this question completely depends on your vehicle’s model, it’s upkeep, driving condition, and manufacturer’s recommendations. Once in a year is what experts suggest, but low fluid level, burnt odour, and transparent fluid are some signals to check or consult an expert. You can check brake fluid change cost or continue reading about these fluids. 

DOT5 & DOT4 brake fluid 

Department of Transport (DOT) segregates chief components of these fluids with a few ratings. Pre-DOT and DOT2 has its chief components as castor-oil or alcohol. Further DOT3, DOT4, and DOT5.1 are glycol-based fluids. Last, DOT5 is the only silicone-based fluid. There are some things to consider if you choose to maintain your vehicle all by yourself. First is never mix the DOT ratings but sometimes adding a higher rating results is higher boiling point, which is good. Second is never mix glycol and silicone fluids. However, you can mix different brands of the same rating and the same chief component. Still, choose only top-notch brands while buying brake fluid online. Some of the go-to brands are definitely Motul, Castrol, Shimano, Prestone, and Amsoil. 

Brake fluid with chlorine 

Here, we would like your attention to the dangers associated with the fluid. As already been stated that you should never try to mix different ratings of DOT, you must not try adding other elements as well. You might see many experiments online related to mixing the fluid with swimming chlorine. If you are up for this experiment, just make sure that you are inside a laboratory and with all your safety gears. This experiment results in 5-30 seconds of explosion and could be a fireball you can see. Other than that, you must maintain the utmost care while brake fluid change. Any discrepancy can lead towards vehicle or handler’s damage. It would be better if you call an expert for any purpose. Speaking of buying the best brake fluid, we have some highlights for you to consider.  

Tips on how to buy Brake fluid online

Brake fluids gradually lowers its performance and efficiency over time, which signals the change of. Once you find the quality standards not up to the mark, it is definitely the time for the fluid replacement. There are signals, such as burnt odour or low fluid level once detected need to be taken care well. And finally, when you think it’s time for brake fluid change, there are parameters to consider related to your vehicle’s compatibility. We are breaking down these parameters in different pointers here. 

  • Chief component – Glycol and silicone are two chief components used in different automobiles. Glycol is best with vehicles having Anti-lock Braking System (ABS) and silicone with those without it. Choosing the chief component depends on the type of your vehicle.
  • DOT ratings – Every DOT rating has a different boiling point, which makes it compatible for different automobiles. For example, DOT5 has a wet boiling point of 185 degree Celsius that cannot be used on vehicles without ABS because they don’t lubricate ABS pumps. 
  • Compressibility – Whether you are applying the brake first time in a newly purchased car or after thousands of miles, the pedal should feel the same. Therefore, compressibility is one of the significant characteristics of brake fluids increment of which makes pedals hard to push. 
  • Corrosion – The fluids you purchase must have the ability to last long without corroding the metals of the braking system. And for that, you can consider Citroën LHM mineral oil-based fluids for longevity. If you ignore the corrosion, it will not be just fluids you will have to replace but the whole braking system. 
  • Viscosity – This characteristic efficiently let fluid flow through the master and slave cylinder, thereby leads to smoother brake performance. Any weather condition – be it extremely hot or cold, it must not change the characteristics of brake fluids, especially viscosity.  

We hope these characteristics of these fluids inside the braking system helps you in buying the right product. Despite looking for the top brands, shopping on the right platform should be something preferred too. For that, we recommend choosing our retail search engine with exclusive shops like Menakart. is Dubai’s leading shopping platform for customers looking for credibility. Thus, the platform is worth looking before hitting the buy button anywhere else. 

Question & Answer

Can brake fluid freeze?

Technically, these fluids being an oil-based fluid cannot freeze. However, certain conditions like extreme cold can lead the fluid to become thick. It can further prevent the fluid from transferring from the master cylinder to wheels. Overall, it has a working point temperature below which makes the pedal stiff, thereby hampering the braking system but not a failure. If your brake fails, it cannot be because of the thickness of the fluid. There might be other causes like condensation in the brake booster or frozen vacuum supply hose. 

What brake fluid to use?

In terms of compatibility, the product must be compatible with your vehicle. For instance, if you have a vehicle with Anti-Lock Braking System (ABS), go for glycol-based fluid. If not, then silicone-based fluid is best. If we talk about performance, check out the availability of quality parameters and if present, you can go buy the product. These parameters are viscosity, compressibility, boiling point, and corrosion. If any of these fails to be compatible with your automobile, the whole braking system fails. 

When to check brake fluid?

Experts suggest changing these fluids every year. But if you feel something odd in your brake pedal, it’s time to check the braking system including brake fluids. However, there are three factors to check the fluid. First is checking the level of fluids – the reservoir has maximum and minimum levels, which needs to be filled if levelled down. Second is checking the colour that needs to be brown. Third is checking the moisture content. Higher moisture content lowers the boiling water, which then demands brake fluid change. 

What happens when brake fluid is low?

Every time you push the brake pedal, fluid from master cylinder transfers to every wheel, thereby creating pressure to stop the vehicle. In case the fluid level is low in the reservoir, every brake pedal will push air into the wheels rather than brake fluid. Therefore, you have to push the pedal to the ground to make it work. It will diminish the performance of the braking system, plus it is dangerous for your life. It is not only important to fill the fluid reservoir but keep some with yourself in your vehicle. 

We hope the information above has provided you with enough data to purchase the best brake fluid and maintain the integrity of fluid well enough.
