After repair or replacement of the master cylinder, there will be a considerable amount of air trapped in the master cyl-
inder piston bore. It is best to relieve this trapped air as much as possible prior to installing in the system. The system
will still require bleeding, but the process will be greatly simplified.
Moisture is the greatest enemy of hydraulic brake systems. All DOT 3 and DOT 4 systems use Poly Glycol-based fluid
that has a relatively high boiling point (DOT 3 = 401°F, DOT 4 = 446°F.)
NOTE: This is a dry boiling point, meaning NO water in the system.
Being Poly Glycol-based, they do not freeze under most conditions. The fluid is hydroscopic, meaning it will mix with
water and still perform.
The J&J filler cap/diaphragm is designed to seal the system from outside moisture, yet allow the fluid level to drop via
the expanding diaphragm.
Mixing DOT 3 and DOT 4 brake fluid will affect the boiling point of the fluid, and is not generally recommended.
DOT 5 fluid is silicone-based and NOT recommended.
