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.
Can DOT 3 be replaced by DOT 4?
Yes. DOT 3 and DOT 4 brake fluid are interchangeable. DOT 4 has a greater boiling point, though.
Due to its high boiling point, DOT 5.1 is utilized in high-performance and heavy-duty applications. The fluids DOT 3 and DOT 4 are compatible with it.
Because DOT 5 brake fluid is silicone, it does not absorb moisture. It is mostly utilized in vintage cars that are kept in storage for extended periods of time and require a brake fluid that doesn’t absorb water because it is incompatible with the other brake fluids.
What distinguishes DOT 3 from DOT 4?
The following are the main distinctions between the two: 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.
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.
