hygroscopic brake fluid is made to absord moisture. That's how the "wet" boiling point is determined, which is much lower than the dry. 3, 4, 5.1

If you put hypophobic brake fluid (DOT 5 does not absorb moisture) it will keep a higher boiling point over it's life, but moisture and the fluid will be separate. Not good.

Moisture is going to happen just with hot engines and cool outside temps. Condensation you can't beat. What happened to Doug is he met and surpassed that wet boiling temp and the fluid was literally vaporized. That vapor is compressed which won't allow the flow of hydraulic fluids.

Charts usually show a 3.7% value of moisture to achieve a "wet" boiling temp. The more we drive with the same fluid in there, the more moisture it's going to absorb and that value will get larger while your boiling point keeps decreasing.

So, moisture is going to happen period. You want it to be absorbed in the fluid, you just want to change it more often if you track your car.

Hence why the SRF stuff is so guuuder

Quote:
Castrol SRF Brake Fluid is a DOT 4 brake fluid suitable for all disc and drum brake systems except those prescribed for mineral oil. Castrol SRF is a high-performance product. Castrol SRF Brake Fluid's unique silicon ester technology absorbs less water than conventional glycol ether fluids and prevents the fluid's high temperature performance from deteriorating. Its wet boiling point of 270°C (518°F) is vastly superior to the minimum requirement of 155°C demanded by the current US DOT 4 specification. Its ability to withstand temperatures in excess of 300°C and superior resistance to the effects of absorbed water have established Castrol SRF Brake Fluid as the world's premier fluid for the hydraulic brakes used in all forms of motorsport and racing. 1 Liter Bottle.

There's a solution to your fluid problems.....


..... I use compressed air, and it's $0.00 a pint

We use air brakes on our trucks at the station, all is good and well until you run out of compressed air

It's not so bad, you just skid to a stop... actually kinda fun

Semi uses 22.5 wheels, some donks are bigger than that, so the drums could conceivably fit... add brake pots, air dryer, replace that goofy parking brake handle with a cool knob on the dash, you're good to go racing!

and at $70 a bottle you'd save a pretty penny.
