Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Peugeot 307; Vehicles With 2.0i 16V 130 kW Engine
- Product Codes: 1622T0
- Other Numbers: Not Specified
Function And Benefits
The vacuum reservoir (vacuum tank) stores negative pressure to guarantee immediate and stable vacuum supply for the brake servo and other vacuum-controlled components when engine vacuum is low (for example during full-throttle acceleration or turbo-related conditions). A healthy reservoir prevents a hard brake pedal, improves brake response, and stabilizes vacuum-operated valves and actuators.
Symptoms Indicating Replacement
- Hard Or Heavy Brake Pedal With Reduced Brake Assistance.
- Intermittent Loss Of Brake Assist Especially Under Load Or During Acceleration.
- Hissing Noise From Engine Bay Or Noticeable Vacuum Leak.
- Erratic Operation Of Vacuum-Operated Systems Or Idle Instability Caused By Vacuum Loss.
Most Common Failure Reasons
- Aging And Heat-Induced Cracking Of The Plastic Housing Leading To Leaks.
- Failure Or Blockage Of The One-Way Check Valve Causing Loss Of Stored Vacuum.
- Degraded Or Perished Vacuum Hoses And Connections Causing External Leaks.
- Contamination From Oil Or Debris Leading To Restricted Flow Or Valve Sticking.
Installation Recommendations
Before Starting, Work On A Cold Engine Where Practical And Use Appropriate Safety Measures. Replacement Is Straightforward For Experienced Technicians: locate The Reservoir In The Engine Bay Near The Brake Booster Or Firewall, Label And Disconnect Vacuum Hoses And Any Electrical Connectors, Remove Retaining Bolts Or Clips, Replace The Unit With The Correct Orientation Of The Check Valve, Reconnect Hoses Securely Using Correct Clamps, Start The Engine And Confirm Vacuum Build-Up And Proper Brake Assist Function. Inspect Associated Hoses And Check Valve During Installation And Replace Any Brittle Or Cracked Lines To Prevent Recurrence. After Fitting, Test Brake Pedal Travel And Ensure No Hissing Or Vacuum Leaks Remain.
