Don’t Ignore This Critical Motorcycle Safety Check

There’s something most Harley-Davidson and Indian Motorcycle riders simply don’t check often enough—and it can absolutely become a serious safety issue.

We’re talking about your brake and clutch fluid.

Even experienced riders (myself included) have overlooked this at times. But here’s the truth: ignoring your brake fluid condition can lead to soft brakes, brake fade, or even complete brake failure.

And that’s not something you want to discover on the road.

Why Harley-Davidson Recommends Changing Brake Fluid Every 2 Years

Harley-Davidson recommends changing your brake fluid every two years regardless of mileage, and honestly, that’s solid advice for any motorcycle or car.

Why?

Because brake fluid naturally absorbs moisture from the air over time. It doesn’t matter if you ride a lot or your bike just sits—this process is always happening.

As that moisture builds up:

• The fluid’s chemical properties deteriorate
• The boiling point drops significantly
• Your braking performance becomes compromised

The Real Danger: Moisture Leads to Brake Fade

Here’s where it gets serious.

Water boils at 212°F, which is far lower than brake fluid. When moisture gets into your brake system and heats up during riding:

• That water boils
• It turns into gas
• Gas compresses much easier than liquid

•

That’s when you’ll start noticing:

• Soft or spongy brake lever
• Reduced braking power
• Having to pump the brakes to build pressure

This is called brake fade—and in extreme situations, it can lead to complete brake failure.

This Applies to Both Brake AND Clutch Systems

Many riders don’t realize this:

On Harley-Davidson motorcycles, the hydraulic clutch system uses the same DOT brake fluid as your braking system.

That means:

Your clutch fluid can degrade the exact same way
And it needs to be checked and serviced just like your brakes
