I have an N reg (1985\6) Defender 110. Can anyone please tell me what DOT brake fluid I should use as I don't have a user manual. Many thanks for your time lovely experts!
 
Dot 4

Don't you have a basic handbook/manual?
 
Use DOT 4 or above. Look at the cap on the brake fluid reservoir that should tell you.

IIRC the DOT rating is the fire retardance offered by the oil. The newer, the more fire retardant the oil the higher the DOT rating.
 
Not fire retardance, it's the boiling point that's the real difference. Also a difference in water absorption.

btw, dot5 is silicon based.. don't mix 3,4 or 5.1 with it.
 
And just like a standard newb, he got his answer and was never herd from again......
