Castor oil - alcohol-type brake fluid has not, mineral oil brake fluid has step-by-step synthetic brake fluid

disabled, synthetic brake fluid is widely used. Ethers, alcohols, esters, mixed lubrication, anti-oxidation,

anti-rust, anti-rubber swelling, and other additives, wide operating temperature range, the easy flow at low

temperatures, brake flexible, high boiling point, evaporation losses at high temperatures, is not easy air

resistance, the metal parts and rubber parts less corrosive,used skid steer bucket
and therefore widely used.
(1) Forklift brake fluid performance
(1) good low temperature performance brake fluid low temperature fluidity, easy to solidification blockage

will allow piping, pumps, etc., will feel the brake pedal hard, the step does not move and can not brake when

the brake. Usually require the brake fluid is not frozen at -40 ℃, flow freely.
(2) the appropriate viscosity of the viscosity is too large, poor low temperature fluidity, decreased braking

performance; viscosity too high temperature environment can not provide reliable lubrication and easy to

leakage. Well in order to ensure the brake cylinder and the rubber cup sliding require brake fluid to the

appropriat e viscosity.budget attachments

(3) the boiling point is higher forklift frequent forward and regressive cycle of work, brake linings in a

braking state for a long time, so the te mperature of the braking system, such as the use of low boiling point,

easy to evaporate the brake fluid, the local braking system pipes filled with brake fluid, steam, air

resistance, causing brake failure. Thus requiring the brake fluid should have a higher boiling point (dry

boiling point of brake fluid does not contain water, the boiling point, wet boiling point is the boiling point

of brake fluid containing water), low evaporation, to reduce air resistance generated .
(4) good corrosion resistance to ensure long-term use of the brake fluid will not be on the metal piping

components have corrosion, to add a rust inhibitor in the brake fluid.
(5), good chemical stability of brake fluid at high temperatures for a long time, the requirements do not

produce thermal decomposition and the coincidence of leaving the oil thickening, sludge sediments are not

allowed to generate.
(6) the impact on the rubber
In the braking system, a lot of rubber seals, in order not to reduce the brake cups and other rubber seals

mechanical strength and flexibility required to be small, so as not to cup a long soak in brake fluid on

rubber expansion brake solution, the intensity, volume and quality of extraordinary change.
(2) the use of brake fluid precautions
(1) Pour a small amount of brake fluid in the palm of your hand, true brake fluid will generally first feel a

bit cold, a moment later will feel some heat, and brake fluid is not likely to be volatile; if you feel the

brake fluid is cold, and will slowly evaporate, it is likely that false brake fluid.
(2) change the brake fluid, be sure the brake system and fluid port, put the oil of the air screw, etc., soil

clean up, to prevent impurities enter. The braking system should be cleaned in accordance with the provisions

of th e Maintenance Manual, to promote the same type of brake fluid cleaning brake system, it is best to not

use alcohol, cleaning agents and the like.
(3) brake fluid has a certain degree of toxicity, not mouth to draw.
(4) brake fluid to the body the appearance of the coating damage will have a "bite paint phenomenon.

Therefore, replacement and filling, to prevent brake droplets fall on the body of the coating.
(5) Do not mix with other brake fluid. Mixture will appear cloudy or precipitation phenomena, it will not only

greatly reduce the performance of the original brake fluid, and sediment particles can clog the pipe to cause

Zhidongshiling serious consequences. Even better compatibility of the same type of brake fluid, if the brand

is different, and can not be mixed. Good compatibility only states that do not occur after mixing with other

products stratification, turbidity and sediment ation phenomenon, does not mean that the performance of the

same mixture of additives added in each product different and mutually exists between the relative balance,

once the mixed with other substances to break the original balance, they will lose their performance.

Therefore, Make sure when you replace the brake fluid of different brands of products to be added washing

lines.
