How often to change out brake fluid?

 

D.O.T. 4 should be changed out every 2 years.

 

I change mine every year when I put it away for the winter.

 

Yikes, I have never changed the fluid on any of the bikes I've owned. Hmmmmmmm.

 

Using dot 5 whenever the mood strikes me.Not a big concern.

 

How often do you change fluid in you car brakes? NEVER I would say this is something you might consider every ten years or so. I would bet that if they say to do this every two years they are doing that to help the service writers.

 

Not so, Dot 3 or 4 is hygroscopic (absorbs water) so after a couple of years 2% water can make brake fade a possibility in extreme use. Then you have corrosion of metal parts from the water. Abs parts are expensive and do fail. Cheap insurance to change your fluid every 2-3 years as manufacture recommended. All manufacturers are stretching maintainace intervals but not brake fluid intervals. Mike

 

well that sucks, I will have to do that messy job now. Two years this fall

 

Get a Mity Vac kit it's pretty easy.
