Brake fluid is one of the essential fluids in the car, and drivers are often aware of this fact. Let us take you through a detailed overview of brake fluid, its importance, different types, and its role in a car’s performance and safety.
Importance of Brake Fluid
Brake fluid is necessary for your vehicle’s brakes to work properly. Without brake fluid, your car won’t stop when needed. Brake fluid is used in hydraulic brake and hydraulic clutch applications. Brake fluids are necessary to transform force into pressure and augment the vehicle’s braking force to stop the car. Here’s how it work:
- The driver puts his foot on the brake pedal linked to the master cylinder full of brake fluid.
- The pistons in the brake calliper of each wheel are compressed.
- The brake fluid is now in motion and transfers force into pressure, enabling brake pads inside the cylinders to slow down and stop the car.
Brake Fluid and Safety
The performance of your car breaks gets affected if there is a brake fluid leak. This is a significant safety hazard. Here is all you need to know about car safety concerning brake fluid:
- While driving, if you notice sudden changes in car braking, it indicates a brake fluid leak. You must stop your car and check the brake fluid level.
- The reservoir must contain over three-quarters full of brake fluid. Anything under this level is concerning and can result in brake failures and fatal accidents.
- If your brake fluid is worn out or old, your vehicle’s braking performance will be hindered.
- Good brakes are even more crucial for fast drivers.
How to Check Brake Fluid Level
Checking your brake fluid level is crucial for your vehicle’s safety. To check the status of brake fluid in your car, follow these steps:
- Clean the top of your brake fluid reservoir cap. Even a tiny particle of dirt that falls in your car’s brake fluid has an impact on your car’s braking effectiveness.
- Open the brake fluid reservoir cap and check if there is enough fluid. Don’t leave the cap open if you don’t plan on changing the fluid. Brake fluids absorb moisture which leads to damages to the hydraulic components and corrodes the brake fluid.
- The brake fluid must be within half an inch or over three-quarters of the reservoir.
- If the car’s reservoir is empty, check for brake fluid leaks.
- Check the brake fluid colour. If it has turned dark, it is time to change it.
- Make sure you bleed the car brakes when chanding the fluid.
If you aren’t sure about doing it yourself, visit an auto workshop for professional help. The cost of changing car brake fluid is between AED 38 to AED 100.
What is Brake Fluid Flush?
Brake fluid flush is a car service offered by mechanics to ensure the working of your car’s braking system. Car brakes are destructible, and several factors including dust entering the brake fluid reservoir, moisture and rust. These things wear out your car’s brake fluid. Mechanics use a vacuum to remove all old brake fluid from the system and replace it with clean fluid.
Preferably, getting brake fluids flushed about every 40,000 kilometres is a good idea, but it is always advised to follow the car manufacturer’s recommendation.
Types of Brake Fluids
Brakes are crucial for your car’s safety – because of this reason, owners are always in search of the best type of brake fluids. Let’s take a look at popular brake fluids:
Brake Fluid Dot 3
This fluid is appropriate for regular vehicles used for daily commutes. Brake Fluid Dot 3 is a poly glycol-based fluid with a wet boiling point of 140 degrees Celsius and a dry boiling point of 205 degrees Celsius.
Brake Fluid Dot 4
This is also a poly glycol-based fluid with a wet boiling point of 155 degrees Celsius and a dry boiling point of 230 degrees Celsius. Brake Fluid Dot 4 has a higher boiling point but needs to be changed more frequently.
Dot 3 and Dot 4 brake fluids absorb water or moisture, which results in a lower boiling point. The water can get absorbed in the brake fluid reservoir from the air, which is why you should always keep the brake fluid reservoir cap sealed tight. If spilt, dot 3 or dot 4 brake fluids can damage your car’s paint.
Brake Fluid Dot 5
This is a synthetic blend fluid consisting of a silicon base. Brake Fluid Dot 5 does not absorb moisture, which enables the boiling point to remain stable. However, since Brake Fluid Dot 5 does not attract water, it can wither away the brake line if left unmonitored. Dot 5 has a wet boiling point of 180 degrees Celsius and a dry boiling point of 260 degrees Celsius. This fluid is specific to race cars and other performance-based vehicles.
FAQs
How often should one change their brake fluid?
It depends on various factors, including your car’s make, the driving conditions it encountered and the recommendation of your manufacturer. Keep checking fluids with regular oil changes. Generally, brake fluids require a change once every four years.
What should I do if the car braking system is causing trouble?
If your car is not braking properly, you should get it fixed as soon as possible. Driving with brakes that do not have the accurate ability to stop when needed is extremely dangerous. You can visit a professional auto workshop to get this problem sorted or to replace the braking system. Here is a list of brakes for sale online in the UAE.
How does one check the quality of brake fluid?
Quality brake fluid is almost transparent with a dash of yellow colour. If the brake fluid is getting dark in colour and smells of being burnt, it must be checked immediately. This means your brake fluid needs to be replaced.
Can brake fluids be mixed?
No. You shouldn’t mix different brake fluids, as all manufacturers have a unique formulation. They can react differently and destroy the car’s braking system. You need to flush all the old out before trying a different type or brand.
That is all the important information there is regarding brake fluid. Taking care of your brake fluid is necessary for your car’s brakes operation. Make sure you use the one that best fits your vehicle. Besides, brake fluids, if you want to replace other car parts, here is a list of auto accessories and parts for sale.
Make sure the car brakes are in perfect condition. Go through these signs indicating brake repair to stay on the safe side.
Moreover, if your car’s brake system has major issues that require frequent repairs, you can consider replacing it with one of these used cars in the UAE.
