When braking, there will be heat generated by friction in the brake booster system, the forklift brake fluid will reduce the heat generated by lubricating and at the same time prevent corrosion.

2. What are the common forklift brake oil types?

There are 4 common types of brake oil in the market as:

– DOT 3 brake oil

– DOT 4 brake oil

– DOT 5 brake oil

– DOT 5.1 brake oil

In particular, brake fluid DOT 3, DOT 4 and DOT 5.1 have a glycol-based composition, while DOT 5 has a silicon-based composition. The biggest difference between these two oil groups is the ability to absorb water: DOT 3, DOT 4 and DOT 5.1 have the ability to absorb water, and DOT 5 does not.

Compared to DOT 3, DOT 4 has a higher boiling point, which will be more suitable for forklifts that use a lot of brakes. DOT 5 has the highest boiling point among all types. Never use DOT 5 brake fluid for brake systems that are designed to use DOT 3 and DOT 4 because it will damage the braking system.

Sometimes it is possible to mix brake oils together if you do not have the same brake fluid available. However, do not mix DOT 5 brake fluid with DOT 3, DOT 4, DOT 5.1 because they differ in their original composition.

Types DOT 3, DOT 4, DOT 5.1 can be mixed together because of the common glycol base, however, mixing is not recommended unless absolutely necessary because mixing can reduce the boiling point of brake fluid.

Why is forklift brake fluid reduced?

Forklift brake fluid is placed in a sealed container, but sometimes we see brake fluid levels getting low. What is the cause?

The most common reason is probably brake fluid leaking out on the ground where your forklift is parked.

Another common cause is brake fluid leaking into the brake booster so Customers need to check brake fluid level regularly and have a solution when detecting problems

Where to buy quality forklift brake fluid? 

In Vietnam, there are many manufacturers and distributors of quality forklift brake fluid which help Customers have more diverse choices.

In order to choose the suitable brake fluid, aside from choosing the type of brake fluid recommended by the forklift manufacturer, Customer needs to test whether the new brake fluid is soluble with the brake fluid currently in use or not?
