JCB Vacuum Pump Hose 9.5x400mm - AZERI PARTS
Vacuum hose by AZERI PARTS, designed for power assistance and pneumatic control systems in JCB machinery. This hose connects the vacuum pump to the brake booster (servo) or other vacuum-actuated components, ensuring their proper operation. Manufactured from a rubber compound resistant to oils and high temperatures found in the engine compartment, the hose maintains flexibility and airtightness even during long-term exposure to vibrations and thermal cycles.
Specifications and Technical Parameters:
- Dimensions: 9.5 mm (internal diameter) x 400 mm (total length).
- Application: Brake power assistance systems (servo) and engine vacuum control.
- Properties: Resistance to wall collapse under high vacuum pressure.

Technical Advice: A leak or a perished vacuum pump hose is the most common cause of a sudden increase in the force required to press the brake pedal (a "hard brake"). When replacing the hose, ensure it is not routed too close to the exhaust manifold or sharp edges of the filter housing. It is recommended to use new hose clamps to prevent "false air" from being drawn in at the fittings, which weakens pump efficiency and can lead to improper operation of the braking system and engine controls.
