Unlike most of us SAU guys, probably flush it once a decade

The hardcore tracks1ut guys I know would flush their brake fluid every 6 to 12 months depending on the amount of track work they did.

LandCruiser used to get a fluid flush every 12 to 18 months.

 

Only because it was about that often the electric motor on the master for brake assist kept dieing and needing to come off.

They've had some weird failures on their brake actuators. One of them was because they added some kind of lubricant to the factory fill brake fluid that aftermarket brake fluid didn't have so it would affect the seals. Another was just mysterious, probably internal corrosion or something eating away at Prius brake actuators. Parts alone for those are a few thousand USD so not a cheap fix.

Give the fluid a really good flush, then go do the same track again. Report back too please

Haha thanks. Will do next year as cars in storage now.....

How hard are you tracking it?

 

Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup.

I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!
