Making brake fluid - when you don't have any (remote use only)
1) READ ALL THE INSTRUCTIONS before use!
Remove all the old fluid. Flush if possible.
The brake fluid is a combination of water and dish washing detergent. The water provides the fluid action, the detergent provides seal lubrication. Yes it will boil if you use the brakes too much. Be careful, use engine braking as much as possible. Cease travel frequently and feel the brake temperature ... if hot wait for it to cool (make a cup of tea?).
Once returned to anywhere with real brake fluid ... flush the system ... anything that will clean out the water .. eg efi cleaner, carb cleaner, methylated sprits, etc etc. Then put in new fresh brake fluid. I'd then flush that out in a day or two with more new fluid...
Your braking system will be expensive to replace. Be certain you need to do this. And if you do ... spend a lot of time cleaning the water out. Consider replacing all the rubber bits in your system after using this method (might be the best way to ensure you have removed all the water).
Yes this can be used for clutch fluid, same thing with out the overheating problems?
