I have recently bought a 1986 Land Rover 90, and am doing a full service on it at the moment.
I want to replace the brake fluid but I am not sure what sort it takes (I have heard that some older vehicles need mineral brake fluid). I have tried searching on the internet but information is harder to come by than for the "true" Defenders.

I know this seems like a trivial question, and that technically it is not a Defender, but can anybody tell me what sort of brake fluid I need to use?

 

You'll be safe with Castrol.

 

Sorry, I don't think I was clear enough with my question. Want I want to know is do I need to use synthetic or mineral brake fluid?

 

Castrol is synthetic, has been for quite a while.
But there are different synthetics, that's why I said Castrol.
