Do you really need to change brake fluid every two years or is this a over kill

 

Yes you do and no it isn't overkill. Most brake fluids are hygroscopic, which means they absorb water. As the water content of the fluid in a brake system increases the heat it can take during braking lowers. Eventually it will boil, creating vapour locks in the fluid and reducing brake effort. It also risks causing corrosion throughout the system, if left too long.

The first vehicle I ever owned with hydraulic brakes was a Harley and I discovered with horror how discoloured and filthy the stuff got. Having realised that I changed it every year. Modern fluids are better, but still need to be changed.

Hope that helps! And welcome to HDF.

 

Excellent advice. Just make sure you use the correct fluid for your scoot. I think all Evo's used DOT 5 (silicone), but Twinkies don't?? Not sure when Harley switched back to DOT 4 but the two don't mix. YD

 

My '04 uses the DOT 5.

 

This thread has a nice tip on how to speed the bleeding process (see last post). YD

Good point! Read the lids of the reservoirs, which will confirm the correct DOT, either 4 or 5. Do not mix them up, as they will fight - the results ain't pretty!
