What do Dual Energy bellows do?
Brake bellows ensure proper transmission of brake pressure. While, at the same time, the service brake (handbrake) is reliably activated, also allowing parking and emergency braking.
What do Dual Energy bellows do?
The front chamber is essentially a service brake chamber and is used to perform the braking function. The rear chamber houses a large, powerful compression spring and diaphragm and performs emergency and parking functions. It is sometimes called a "little pig".
How do I know if my brake bellows are bad?
When should you disengage your brakes via the DE bellows?
Disabling the Dual Energy Blower is only done in extremely rare cases and taking all necessary safety measures by qualified personnel to prevent serious and irreparable injury and only when a failure has occurred in the air brake system and you need to move your vehicle to a safe area only, not in normal mode. This process releases the spring tension in the chamber that operates the parking brake (service) and renders the wheel without parking brakes when complete.
What quality should I choose when buying a bellows?
The bellows is one of the most basic parts of your vehicle's braking and expansion system.
The choice during the purchase must be based on criteria regarding the certifications that the spare part has received regarding the European directives (ISO) for its safe and good operation. Its price should not be the only selection criterion, as a wrong choice can lead to disproportionate replacement costs by causing wear and tear on other parts of the braking system such as discs, pads, calipers and other parts.
