What Kind Of Brake Fluid Goes In A Boat Trailer? What type of brake fluid should I use? DOT 3 or DOT 4 is what should be used in your boat trailer.

The primary differences between the two include the following: DOT 3 brake fluid will absorb less water than DOT 4 from the air over time, meaning you’ll need to have your fluid changed less frequently. DOT 4 brake fluid has higher dry and wet boiling points, making it safer for higher temperatures.
Does it matter what brake fluid I use? YES! It’s very important– the fluid specified by the original vehicle manufacturers must be used.
DOT 3 & 4 brake fluid is a mineral based fluid.
DO NOT use DOT 5 in a vehicle equipped with ABS (Anti-Lock Brake System).
