Brake bleeding and pad material

[Fummins]

I've never done it. There are a bunch of Mirage here with over 400,000kms, some with over 500,000kms. I've replaced a few wheel cylinders on higher mileage cars that see a lot of dirt roads but that's about the only time I ever open up a bleeder screw.

...we should open the bleeding valve and then push the brake piston back. They claim that this extra step will avoid long term issues with the abs module. They say the brake fluid on the calipers is more contaminated and will be sent to the ABS module if we do not open the bleeding valve.

They teach that in school. I might do that if I was working on something older and I knew the fluid was really bad.

I change the brake fluid regularly every few years or so, but as a hypermiler not for deminishing the risk of boiling. I change it because the increasing water content will eventually cause rust inside the ferrous parts, leading to expensive and totally preventable repairs.

That's good to know, thanks. What about ABS modules with issues, did you had any?

Nope. The only abs issues that I've seen have been from damaged wiring for the rear speed sensors near the wheels.
