It's a 10mm hex head, I did battle with mine last night. Thread size above would be close

As much as they're a cool idea, they hardly seem worth it to me. At most you're probably going to bleed the brakes half a dozen times in the time you have the car. They don't achieve anything a normal 1 man brake bleeder wont, they cost just as much and they're only applicable to one vehicle.

Isn't the service interval for brake fluid one year?

But agree with your statement other than that.

You're meant to replace the fluid every 2 years.

I'm sure all AZers follow the maintenance schedule religiously. :D

And people complain about sierra brakes. :?

I've bled through an entire bottle till new stuff comes out, but never actually set out and said : "I'm gunna change the brake fluid today" so can't talk either.

and do we know why they recommend to change it regularly? :?

i only remember this cause the old man spat it at the mazda mechanics that serviced ones of mum's mazda's in the late 80's & left the cap of the master cylinder, not only splashing brake fluid everywhere but for the fact that brake fluid absorbs water (hygroscopic)... the old boy made them flush/bleed the system & got a few free services out of them back in the day. :lol:


wiki says this stuff wrote:
(DOT 3, 4, and 5.1) brake fluids are hygroscopic (water absorbing), which means they absorb moisture from the atmosphere under normal humidity levels. Non-hygroscopic fluids (e.g. silicone/DOT 5-based formulations), are hydrophobic, and can maintain an acceptable boiling point over the fluid's service life, although at the cost of potential phase separation/water pooling and freezing/boiling in the system over time - the main reason single phase hygroscopic fluids are used.

Basically my understanding is it goes spongy (pedal feel) and allows the system to deteriorate internally (corrosion), due to the fluid taking on water.

Basically what you have referenced. The Holden stealership here claims they change it every service due to the humidity up here, to me that sounds like bunk. But my brakes were definitely firmer after I got it back.

Its like 8 bucks a bottle for brake fluid.

it would have to be pretty bad for it to feel spongy. Its recommended every 2 years, some cars have it as part of the scheduled services (Kias all have it every 30k/ 2 years)

at work if its not part of the service you can tell if it needs a flush if the master cylinder res has what looks like algae/slime on the inside above the fluid line.
