I am wondering do I need to change my brake fluid. I replaced the cylinders in the back a year and a half ago and had to top up the fluid. Before that I don't know when it was changed. Is it necessary to change it every few years to reduce corosion?

Thanks

I wouldn't say it's necessary, but it definetely couldn't hurt. It's always better to change your brake fluid more often (just like any other automotive fluid). Just make sure you bleed the brakes at all four corners too just so no air gets in (although you are going to have to bleed them anyway to get the old fluid out).

Yep, a change is a very good idea. All major manufacturers recommend it after so many miles. Brake fluid will absorb moisture over time and corrode from the inside out, plus will lower the boiling point of the fluid. Old brake fluid will turn dark colored. Just bleed each brake untill you see new, clear fluid. Make sure to keep the MC full when doing it and use only new fluid from a sealed container.

Okay so, I will go for it. If I take all the old fluid out of the reservoir thing and put in new fluid do I have to bleed the master cylinder? or will I get away with doing the brakes at each wheel.

Thanks.

You can take most of the old fluid out and fill it with new fluid. Just dont take it all out. Any old fluid at the bottom of the mc will quickly be bled away at the first brake you bleed.

The reservoir at the master cylinder has two sections. Which is for the front brakes and which is for the back.

Thanks.

The back is for the front and the front is for the back! honest!

The larger rear-ward reservoir is for the front brakes.
