Nic.Clay Posted January 8, 2017 Share Posted January 8, 2017 When I acquired a Stalwart I had it drummed into me that I should never take any standard brake fluid within 50 feet of the vehicle. Apparently the standard DOT 4 fluid will destroy the seals designed for hydraulic fluids. Consequently I used a Comma LIC10 hydraulic fluid for a couple of years. It seemed to work but the system did weep in places - particularly the accelerator slave. I was then told I was still doing it wrong and should only use LHM (Lockheed Hydraulic Mineral?) for the brakes accelerator clutch and power steering. I obediently swopped over though I didn't drain the system just changed to LHM. Overall a big improvement - slave cylinder isn't loosing anything now. The winch power steering reservoir still needs regular attention, but otherwise the LHM seems to do what it should. Nic 09ER31 Quote Link to comment Share on other sites More sharing options...

Nic.Clay Posted January 8, 2017 Share Posted January 8, 2017 I misread your first item - 'I'm rebuilding my Stalwart calipers with normal brake fluid.' I needed to go on a bit further and take the rest of the sentence into account! Nic Quote Link to comment Share on other sites More sharing options...
