Hi- I just bought my first Land Rover. It's a nice Disco II 1999. I was topping up fluids when I realized I added approx. 4 oz. of DOT 3 brake fluid and the cap on the master calls for DOT4. Did I pull a major boo-boo? I haven't driven it yet -should I try to shop-vac the top off and add DOT4? Thanks everyone!

 

yeah suck all of it out and replace it all. check out the 60k service sticky in the disco section. welcome to the forum.

 

Yes you did, suck it all out then do a full 3 pint brake flush to make sure you get it all out, ASAP.

 

I work at a Ford dealership-12 miles away. Do you believe driving it will hurt anything or should I let it sit-suck it out and replace it prior to driving it?
