What is a shock vacuum bleed pump?
A shock vacuum bleed pump is one of the most essential tools for shocks that optimizes the process of maintaining and enhancing the performance of dampers and forks in various vehicles such as cars, trucks, or bicycles. This device helps in filling shock absorbers while ensuring that there are no bubbles of air left in the oil chamber.
During the shock bleeding process, a vacuum bleed machine creates a vacuum inside the shock absorber and starts to fill in the suspension oil while eliminating any trapped air that comes from a bottle of fluids you’ve used. The bubble-free oil fluid is crucial for foaming prevention and retaining consistent suspension system performance in the long run. Meaning, you can avoid such issues as suspension sagging.
At LABA7, we have three different vacuum bleed pumps for shocks and forks – it’s the MODULE, DAILY, and PRO models. The core set of features is the same from device to device; however, they’ve been designed to fit different needs. When developing them, we aimed to build a technology that could create a deeper vacuum in order to eliminate trapped air from the oil most efficiently.
Overview of LABA7 vacuum bleed pumps
Each LABA7 vacuum bleed pump is fully automated, ensuring you can bleed dampers or forks using safety-friendly vacuum levels, which is virtually impossible with manual vacuum bleeder pumps. Nevertheless, each of our pumps has been developed for different use cases, differentiating in certain technical aspects.

- Wait for the shock absorber to complete filling, or halt the filling operation at any moment by pressing the back button and choosing the confirmation icon.
Bear in mind to open all external adjusters on the shock absorber, push the separating piston to the bottom, and install the circlip (fastener) to prevent the free piston from shooting out when filling.
Safety & Best Practices
Proper preparation of your shock absorber is critical for safe and effective bleeding. Follow these essential steps before starting the vacuum bleed process.
Prepare External Adjusters
Always open all external adjusters on the shock absorber before beginning. This prevents dangerous pressure buildup inside the shock during the bleeding and filling process, ensuring fluid can flow freely without resistance.
Secure the Separating Piston
For shocks equipped with separating pistons, push the piston all the way to the bottom of its travel before connecting to the bleed pump. This creates proper clearance for oil filling and prevents air pockets from forming.
Install the Circlip (Critical Safety Step)
After positioning the separating piston at the bottom, install the circlip (fastener) securely. This small component is essential—it prevents the free piston from violently shooting out under pressure during the filling operation, which could cause serious injury or equipment damage. Never skip this step.
Additional Safety Reminders
Position the shock below the external tank with the bleed port facing upward. Wear safety glasses and gloves when handling suspension oils. Inspect all hose connections before starting, and keep the emergency stop button within easy reach throughout the operation.
Is it worth getting a shock absorber vacuum bleed pump?
When questioning whether getting a shock absorber vacuum bleed pump is worth it, it’s always important to evaluate your intentions and determination to maintain the quality of the suspension systems you work with.
