[ballbag racer]

I'm just putting my rear brake back together and just wanted to know if using 5.1 fluid was ok to use? I have read a couple of articles about brake fluids and it would seem ok? Just wondered what you guys thought about it??

Cheers

Why? DOT 5 is the silicone based fluid that should not be used.

DOT 5.1 has twice the boiling point properties of DOT 4 and is fully compatible.
I've been using it on my bike since I started in DD in 2008.

Castrol SRF is great for race cars where the fluid can reach extraordinary temperatures, but on our little bikes to be honest DOT 4 is satisfactory too.

SRF is dot 4 as for dot 5.1 you'll be changing more often but if you've got the money then go fr it.

I know it is twice the price of DOT 4 but SRF isn't cheap either. I only as a matter of course change the fluid mid season, so twice a year, 250ml is hardly going to break the bank.

Use 5.1 and change once a year if it's lucky. Maybe it's because I don't use the brakes

You're right. I like SRF which isn't cheap either
