Is Honda’s brake fluid unique?
Now that my 2017 CTR is three years old, Maintenance Minder “7”: Replace brake fluid, is activated. Naturally, this raises the issue of what kind of replacement fluid to employ.
I’ve put this car through its maximum amount of track time with 100% stock equipment, and it worked out perfectly for me. My biggest concern is that I want to use this automobile as a daily driver for at least 15 years.
I brought it to a local high-performance shop that specializes in tires and suspensions for stock vehicles used in amateur racing and was pleasantly surprised when they advised me to stick using Honda brake fluid (I think for an ordinary Civic they would have used Castrol DOT 3). I also observe what Honda states in the CTR Owner’s Manual:
You should only use DOT 3 or DOT 4 fluid from a sealed bottle as a temporary substitution if the required brake fluid is not readily accessible.
Any non-Honda braking fluid might lead to corrosion and shorten the system’s lifespan. As soon as feasible, have Honda Heavy Duty Braking Fluid DOT 3 replaced and the brake system cleansed.
Do DOT 3 brake fluids differ in any way?
The systems and all DOT 3, 4, and 5.1 braking fluids are compatible with one another.
No polyethylene glycol-based solution will affect rubber components that are in good health. Additionally, no rubber components will be harmed or deformed by the additive packets. New DOT approved brake fluids won’t harm even an older rubber component that contains a lot of natural rubber.
The breakdown of the additive package is what destroys rubber components. The fluid’s pH and viscosity are within the control of the additive package. Rubber and metal components will corrode over time if the braking fluid is unable to manage the pH or other corrosive substances. Use DOT 4 or 5.1 brake fluid if you have an older car and are concerned about the fluid boiling.
How often should the brake fluid on a Honda be replaced?
For your brakes to be durable and dependable, changing your brake fluid is essential. The brake fluid in your Honda should be replaced, on average, every two to three years.
You should consult your owners manual for further information regarding brake fluid changes since every car has certain requirements. For instance, if you drive more than the average person, you might need to change the brake fluid more frequently.
But if you’re still unclear about how long you should go between changes, keep in mind that when it comes to car maintenance, it’s better to be safe than sorry. It is far preferable to change it a little too frequently than to wait too long.

Can you mix DOT 3 with DOT 4?
Since DOT 3 and DOT 4 brake fluids are both glycol-based, mixing them is not a problem, but you should be aware that the boiling points will alter.
What occurs if DOT 3 is applied instead of DOT 4?
Over time, DOT 3 brake fluid will collect less water from the air than DOT 4, resulting in fewer frequent fluid changes. Due to its higher dry and wet boiling points, DOT 4 brake fluid is more heat-resistant.
How important is the brand of brake fluid I choose?
DOT 3 and DOT 4 fluids are both glycol-based, but because their chemical make-ups differ, they will affect the system in different ways. It is essential to continue using the precise brake fluid that the manufacturer advises in order to guarantee that the system functions as it should.
Honda brake fluid’s color?
As you drive and collect dirt and debris in the system, the color of fresh brake fluid gradually changes to a darker, oil-like shade, reducing the effectiveness of your brakes.
Can DOT 3 and DOT 3 Synthetic be combined?
Dot 3 does mix with all types, but not Dot 5. Dot 5 is silicone brake fluid, while Dot 3 is synthetic brake fluid. Silicone and synthetics don’t mix.
Is DOT 3 brake fluid from Autozone synthetic?
For all vehicles requiring DOT 3, Prestone’s DOT 3 Motor Vehicle Brake provides improved performance in comparison to DOT regulations. To guard against overheating, brake fade, and performance loss brought on by water absorption, this synthetic fluid starts out with a higher dry boiling point than the DOT minimum standard.
Replace brake fluid
The first step in learning how to change brake fluid is to remove the old fluid from the reservoir and replace it with new fluid.
Some automakers advise changing brake fluid every 24,000 miles or every two years. Others fail to mention changing brake fluid at all. However, checking your brake fluid is simple. To check the color, simply dip a test strip into the fluid and match it to the chart on the container.
You can perform the fluid switch that comes close to a complete brake fluid cleanse, but not quite. You won’t completely replace the old fluid with new fluid during this treatment, but you will add enough new fluid to notice a difference.
Is it necessary to flush the brake fluid?
One of the most essential components of a safe car is probably the brakes. But a lot of people might be asking themselves, “Is a brake fluid flush really necessary? Yes, to answer briefly. Hydraulic fluid is used by your braking system to increase pedal pressure from your foot. This is what enables you to quickly and easily stop a large, moving vehicle. To keep this performance, your brake fluid needs routine maintenance. Here is all the information you require regarding brake fluid flushes.
What occurs if brake fluid is not changed?
The brake reservoir, where the brake fluid is housed, will become contaminated with moisture if you don’t change your brake fluid as advised by the vehicle’s manufacturer.
Your braking fluid will inevitably become polluted with “debris buildup” as it ages. Your brake system’s many seals and hoses might gradually lose little amounts of rubber as they wear down. Additionally, rust particles may get up in your brake fluid as a result of metal components corroding and rusting due to moisture-rich brake fluid.
Your car’s ability to stop suffers substantially from not changing the brake fluid, which results in subpar braking performance. Most of the time, you can tell by pressing the brake pedal: if it feels excessively spongy, your brake fluid is probably about to fail. You may find that stopping your car requires more work and time, and in some situations, you may even need to pump the brakes in order to build up enough pressure for a secure stop.
If you’re moving at any speed, the uncomfortable idea that your brakes could completely fail is also a deadly one. This may occur if the boiling point of the braking fluid is reached while the vehicle is in motion, particularly if the boiling point was intentionally decreased due to moisture contamination.
Does Honda advise changing the brake fluid?
A brake fluid exchange entails completely removing the old brake fluid from your Honda and replacing it with fresh brake fluid. The brake fluid flush is another name for this treatment. For your Honda CRV or other Honda car, this is a maintenance service. When moisture has entered your car’s hydraulic braking system, you need to interchange the brake fluid. A brake fluid exchange is also recommended as part of the installation of a new braking system or the replacement of brake pads. In the end, your Honda-certified technician will inform you if the brake fluid replacement will improve your car’s braking performance.
