Dot 3...any brand is common.
All cars i have owned used dot 3 brake fluid,..check your manual,but thats a common fluid,...dot 3 and 4 absorb water and dot 5 does not..hope this helps.
Short answer: DOT3 and DOT4 are the most commonly used at present.
Long answer: When you look to purchase brake fluid, you're likely to get DOT3, DOT4, DOT5, or DOT5.1 DOT3/DOT4/DOT5.1 are glycol-based (Polyalkylene Glycol Ether), while DOT5 is silicone-based. DOT3 and DOT4 fluids are essentially interchangeable - the only real difference is their boiling point. Theoretically, you could interchange DOT4 and DOT5.1 fluids, too, but I wouldn't really recommend it. DOT3/4/5.1 cannot be mixed or interchanged with DOT5 under any circumstances - They mix like oil and water (in other words, they don't) and the silicon-based fluids can destroy the seals in brake systems which rely on the moisturiser additives that are present in DOT3/4/5.1 fluids.
Silicone-based fluid (DOT5) is not compatible with most ABS systems, because it doesn't lubricate the ABS pump like the glycol-based fluids.
Other things about silicone-based (DOT5) fluids:
#1: they are resistant to absorbing water, which is why their wet boiling points are so high. The problem is that any water content eventually pools in the low spots of the brake system and causes rust.
#2: they don't strip paint.
#3: putting this fluid in systems which have had DOT3/4 fluid in them might cause the seals in the caliper and master cylinders to malfunction. Which means they need replacing. Which is expensive.
BTW: Don't bother to ask me why DOT5.1 is glycol and DOT5 is silicon-based. It doesn't make any sense to me either.
A general DOT 3 brake fluid is use in small vehicles
