Why are there Wiper seals on hydraulic cylinders?
Wiper Seals are available in several styles to keep contaminants from entering the cylinder. Besides direct wear to the rod seal, external contamination, if allowed to enter a hydraulic system, can have disastrous consequences.
When to use HNBR as an elastomer?
Obtained by hydrogenerating the nitrile copolymer, HNBR fills the gap left by NBR and FKM elastomers when high temperature conditions require high tensile strength while maintaining excellent resistance to motor oil, ATF, sour gas, amine/oil mixtures, oxidized fuels and lubricating oils. Green HSN is commonly used in refrigerant R134a applications.
Why do air brakes need to be clean?
As vehicles work to optimize uptime and become more fuel-efficient, more and more air-braked vehicles depend on clean, quality air from their air dyers to keep solid, liquid, and aerosol contaminants – like water and oil – out of the air brake system.
Where is the hydraulic brake light switch located?
For most American-made vehicles built between the early 1930s and the late 1960s, the brake lights were activated by a hydraulic stoplight switch mounted either directly to the brake master cylinder or to one of the steel brake lines near the master cylinder.
What are the symptoms of a bad brake light switch?
When the brake light switch does fail, usually the vehicle will produce a few symptoms that can alert the driver that a problem has occurred. Brake lights stay on. One of the symptoms commonly associated with a bad brake light switch are brake lights that stay on at all times.
What is the function of the brake light switch?
The brake light switch is the electrical switch that is responsible for activating the brake lights. When the pedal is pressed, the brake light switch makes contact, and the the brake lights are illuminated. While the exact designs of brake switches can vary, they all serve the same purpose of activating the brake lights when the pedal is pressed.
What does the anti lock braking system do?
Basically, the function of the anti-lock braking system is to keep your vehicle’s tires on the road as you aggressively step on the brake. That way, the wheels don’t lock up or skid uncontrollably on the road during the braking process. This is particularly important if the road is slippery or wet.
