Wagner DOT 4 Premium Brake Fluid
Wagner DOT 4 Premium targets OEM replacement buyers who need dependable, corrosion-inhibited fluid with stable performance in electric-over-hydraulic trailer systems; it offers a good balance of wet boiling resistance and seal compatibility for regular towing duty. In comparison to the list, Wagner generally delivers broader availability and value similar to ATE TYP 200 but without the extreme thermal margin of racing fluids like Castrol SRF or Motul RBF, making it a practical all-around choice for many horse-trailer operators.

Motul RBF 600 Factory Line Racing Brake Fluid
Motul RBF 600 Factory Line Racing Brake Fluid is the technical leader for thermal stability and moisture tolerance, offering the highest boiling points in this group and the best protection against vapor lock during sustained heavy braking typical of loaded horse trailers. Although significantly pricier and over-specified for light use compared with Prestone or Wagner, Motul is the preferred option when maximum safety margin, repeated high-temperature performance, and reduced brake fade are the primary concerns.
