and can be readily mixed or swapped without adversely affecting the brake’s performance or its characteristics.
Can I mix DOT 3 and DOT 4?
Yes. DOT 3 brake fluid is compatible with DOT 4 brake fluid
. However, DOT 4 offers a higher boiling point. DOT 5.1 is used in high-performance and heavy-duty applications due to its high boiling point.
Can you use oil as brake fluid?

Adding brake fluid to the oil tank would cause the seals on the engine to break down
just as pouring oil into brake lines would cause brake failure.
How do you put brake fluid in a mountain bike?

Is DOT 5 brake fluid universal?
Since DOT 4 and 5.1 are both glycol-based brake fluids
they are compatible with each other
, which means they can be readily mixed without harming your brake system. It is important never to mistake DOT 5.1 (glycol-based) with DOT 5 which is silicone-based and should never be mixed with any other DOT fluid.

Can you use baby oil for brake fluid?
Shimano use mineral oil in all their brakes. The proper stuff is pretty thin, and specially formulated (so Shimano claim anyway) to have a quite high boiling point.
Baby oil could be used in an emergency, but its higher viscosity could affect performance, and may have a lower boiling point than the proper stuff
.
Which brake fluid is best?
Our pick for the best brake fluid is the
Motul Dot-4 100 Percent Synthetic Racing Brake Fluid
. While it’s slightly pricier than other brands, it improves pedal feel, protects against water penetration, and increases performance for both daily drivers and racers.
What is DOT 5 used for?
DOT 5 is
silicone-based brake fluid
and is used in most new cars today. DOT 5 is expensive, but it has a dry boiling point of 356 degrees. Newer brake rotors tend to be smaller and thinner, which means they disperse heat a lot less efficiently. Also, DOT 5 does not absorb any moisture.
What happens if you use the wrong brake fluid?
Using the wrong fluid can cause
poor lubrication, overheating, and possibly transmission failure
. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.
Does brake fluid go bad?
