M101A2 Surge Brake Help

[CaryHenry]

I just picked up my first M101A2 on Monday. When I checked the master cylinder at GL, it was bone dry. As I didn't have access to the TM at the time, I was unaware of the brake fluid spec. I stopped on the road and picked up a quart of DOT 3/4 brake fluid to top things off. After reviewing the TM when I got home I realized that I should have filled it with DOT 5 fluid. Now I am worried I am going to destroy my braking system. What should I do? Should I bleed about a pint of DOT 3/4 through the system and run with that stuff, or should I buy a quart of DOT 5 and bleed all of it through the system to remove the DOT 3/4 fluid. I know the two fluids are not compatible, and that I must remove all of one or the other to prevent gumming of the fluid. What I want to know is if using the DOT 3/4 fluid will damage the braking components. Thanks for the help!

Your choice on fluid. Just run plenty through to flush it!

I doubt it. Theres quite a few threads dealing with people running dot3 vs dot5, http://www.steelsoldiers.com/deuce-modification-hot-rodding/51445-dot-5-seals.html is one of them.

If it were me I would flush the system with alcohol and fill and bleed with wichever you choose.

Also I'd look into why the master cylinder was empty/low in the first place.
