Agree with Chris - DOT 5 & DOT 5.1 are NOT the same thing.
DOT 5 is Silicone fluid
DOT 5.1 is Mineral fluid formulated for ABS systems - Totally incompatible with DOT 5
Our daily drivers are all on DOT 4 mineral brake fluid, the classics with hydraulic brakes are all on DOT 5 silicone fluid and the Austins are all cable brakes
We've run '50's & '60's Giulietta Alfa's on DOT 5 Silicone for 21 years now, never looked back, but the change from DOT 4 Mineral to DOT 5 Silicone requires a total strip & rebuild & a comprehensive flushing of the lines & cylinders. Cleanliness is next to Godliness when it comes to brakes, Mercedes Benz SA determined that 0.04% mineral oil (ie dirty hands) in brake fluid is enough to destroy all the washers in the system.
If anyone wants to change over, contact me via Private Message & I'll walk you through the process
