The Importance of DOT 5 Brake Fluid Color – Maintaining Your Braking System

For motorcycle fanatics, brake fluid is an essential element to maintain. It enables the pressure from your brakes to be transmitted onto the pads, so it’s imperative that you ensure its condition consistently. One method of assessing this might be through examining the DOT 5 brake fluid color.

What is DOT 5 Brake Fluid?

DOT 5 brake fluid is silicone-based and has a higher boiling point than other types of brake fluids, making it perfect for high-performance motorcycles that need extra durability. However, this superior formula does come at an increased cost as well as being incompatibility with some rubber seals and hoses.

DOT 5 Brake Fluid Color

DOT 5 brake fluid is easily recognizable due to its signature purple hue. But, if you spot any discoloration in the form of brown or yellowish tones coming out with your old brake fluid, it’s likely that yours has been overdue for a change. This could be an indication of contamination and corrosion within your braking system – both dangerous factors which can potentially lead to brakes failure.

What to Do If Your DOT 5 Brake Fluid Color is Brown

If you observe that your DOT 5 brake fluid color is discolored, ranging from brown to yellowish, take quick action. To restore the proper purple hue of your brake system, it’s highly advisable to flush out most of the old fluid and replace with new. Afterward, ride your bike for a bit before flushing again – this second round ensures that any lingering debris or sediment has been removed fully. Keep an eye on the color of your fluids in order to maintain safe brakes.

To guarantee that rust and corrosion do not accumulate inside your master cylinders, strip the parts and clean them at the conclusion of each riding season. This precaution is especially important if you experience high humidity or ride in wet weather often.

How Often Should You Change Your DOT 5 Brake Fluid?

As the 03 motorcycle manual suggests, brake fluid should be replaced every two years – yet it’s recommended that some riders do this annually as a safety precaution. It is easy to change and won’t cost too much either.

In conclusion, if the DOT 5 brake fluid color appears brown or yellowish in color, this is a sign that it has not been changed recently. It’s wise to flush out the braking system until you can observe its original purple hue again. Additionally, at the close of each riding season make sure to clean and strip your master cylinders so no corrosion will accumulate within them.

To ensure your safety while on the road, it is highly recommended that you replace your brake fluid yearly as a precautionary measure. As motorcyclists, we should always prioritize safety; taking care of our braking system should be at the top of our list.
