Dot 3 brake fluid and the regular type Ethylene Glycol, green, antifreeze....more here:

Table 2-10 of the-20 maintenance manual, Chapter 2, Section 13 gives the mix rates for different temperature zones

This is what is listed for the brake fluid:

B-34. Brake Master Cylinder
Clean the top of the fill cap and also the housing area around it. Remove the cap and observe the fluid level. It should be half an inch below the top of the fill-hole. If required, add brake fluid to one-half-inch below the top of the fill-hole, using only heavy-duty brake fluid conforming to specif ication VV-B-680. Be sure sure to handle the brake fluid in clean dispensers and containers that will not introduce even the slightest amount of other liquids or foreign particles. Replace and tighten the fill cap.

AND:

Use Hydraulic Brake Fluid (HB), non petroleum base only. Use of hydraulic fluid petroleum base renders brakes inoperative.

Dot 3 and Dot 4 brake fluid fit this spec....Dot 3 being common...remember that brake fluid absorbs water...thus it is not petrol based...there was an issue about that some time back on the old board, so just clarifying up front here...
