1. What are the fundamental differences between synthetic fluid and conventional DOT 3 and 4 brake fluid ?

2. Technician A says synthetic fluid might be able to last a little longer because the fluid can absorb more water before the fluid drops below a critical boiling point. Technician B says it is the additive package and environment that has the greatest impact on lifespan, no matter what type of base stock is used. Who is correct?

3. True or False: The higher the DOT classification, the higher the boiling point, meaning the better the fluid is at resisting heat.

4. Technician A says brake fade happens when the rotors get too hot. Technician B says brake fade is just an imaginary condition. Who's right?

5. Technician A says all brake fluids are compatible with each other. Technician B says DOT 5 brake fluid is made of silicone so it shouldn't be mixed with conventional fluid. Who is correct?
