I'm putting new brembo discs and pads on my car and changing to braided hoses so I'm going to change to 5.1 brake fluid but after been told 3 different amounts to buy can anyone tell me how much I will need? 1 2 or 3 litres ?

Thanks Lee
 
I used Motul RBF600 with the same discs and pads your using and was advised by Tegiwa that I would need 1.5litres.
 
You have already asked this question and had it answered in another thread.

1litre is sufficient for a change/bleed.
 
I bought 1.5 litres to be on the safe side, I had a little left over. The dot on brake fluid I think refers to brake temperatures dot 3 gives lowest temp rating (dry and wet), dot 4 is slightly higher and dot 5 is for extreme temps. Honda recommend dot 4 fluid this will be fine, you won't need a higher dot rating unless you track the car as well. Or drive to the extreme.
 
Decent fluids like Motul RBF600/660 and ATE Super Blue are Dot 4. Its all i`d ever really use. Even in pure track cars i know of still use Motul RBF600/660.
 
i bought 1 litre of rbf600 dot 4 and had a little left over when i finished
 
Dot5 is made from a different compound from dot4 and can degrade your brake lines with prolonged use as the Honda lines are made for dot4. So I wouldn't recommend using dot5 on a Type R.

Dot5.1 however is the same as dot4 with bells on and is fine to use in a dot4 system.
