Starting at $212.95, AutoBuffy stocks 2 power brake booster vacuum pumps from Vaico and URO. This pump generates the vacuum pressure that powers your brake booster, giving you assisted, low-effort braking. When it fails, pedal effort increases sharply and stopping distances grow — making it a safety-critical repair that should not be delayed.
The main decision is whether to buy an OE-equivalent direct-fit replacement or an upgraded unit, and whether to choose a new pump or a remanufactured one. Fit matters most — confirm the pump matches your engine type (diesel or gasoline) and mounting configuration before ordering.
| Option | Best for | What you get |
|---|---|---|
| OE Direct-Fit New | Owners who want a straightforward swap with no modifications | Brand-new pump engineered to factory specifications; includes mounting hardware and seals; longest expected service life |
| Remanufactured / Reman | Budget-conscious repairs where the core can be exchanged | Professionally rebuilt to OE tolerances; typically carries a warranty; lower upfront cost than a new unit; core charge may apply |
| Diesel-Specific Pump | Diesel engines that lack intake-manifold vacuum and rely entirely on a mechanical pump | Higher flow capacity rated for diesel vacuum demands; heavy-duty internal vanes; often required where no alternative vacuum source exists |
| Performance / Heavy-Duty Upgrade | Towing, fleet, or high-demand applications requiring consistent vacuum under load | Higher CFM output maintains booster assist during hard or repeated braking; reinforced internals for extended duty cycles |
Access the vacuum pump — typically mounted on the engine block, cylinder head, or accessory bracket — and disconnect the vacuum line and any oil feed or return lines before unbolting the pump. Install the new pump with a fresh gasket or O-ring, reconnect all lines securely, and start the engine to verify vacuum builds and no leaks are present. Confirm brake pedal feel is restored before returning the vehicle to service.
