44GPW Posted January 30, 2013 Share Posted January 30, 2013 Guys, need to replenish my brake fluid for the first time. The manuals state Fluid Brake Hydraulic No3. What's the equivalent modern version? Thanks Richard. Quote Link to comment Share on other sites More sharing options...
0 owl Posted January 30, 2013 Share Posted January 30, 2013 hi the best hydro is dot 3 or 4 but do not use dot 5 or silica base as it effects the old type of rubber seals tracy Quote Link to comment Share on other sites More sharing options...
0 Pete Ashby Posted January 30, 2013 Share Posted January 30, 2013 hi the best hydro is dot 3 or 4 but do not use dot 5 or silica base as it effects the old type of rubber seals tracy As Tracy notes Dot 4 is a good bet and will give no problems, work the pedal on a regular basis when the truck is laid up and change the fluid every couple of years. Keep clear of the silicone based fluids unless the system is disassembled and completely flushed out with alcohol then blown through with compressed air then new silicone compatible seals fitted must be fitted. This subject has been discussed before on the forum in detail try a search. The silicon vs conventional brake fluid debate has pros and cons on both sides but one thing is certain they don't mix.
