A workshop device must improve over time, just like the products it is used on. For Werner Rogg, owner and chief engineer of workshop equipment specialist Romess, this is self-evident: "Based on our many years of experience working with renowned car manufacturers, we have continually developed our brake maintenance devices."

Romess relies exclusively on electro-hydraulic systems, designed to be simple yet smartly conceived. As the first provider, the Schwenningen-based company introduced devices using this technology — which is superior to pneumatic systems. A service technician can easily operate them alone, allowing for independent brake fluid changes, bleeding of the brake system and hydraulic clutch, leak testing in the low-pressure range, and testing the smoothness of the brake cylinders.

Another advantage weighs almost more heavily than the numerous benefits in handling: malfunctions, as often encountered with pneumatic devices, are excluded here. A prime example of this high technical standard is the S 30-60 model, used in advanced workshops for the efficient filling and bleeding of all hydraulic clutches in trucks, cars, and motorcycles. It was specifically designed for workshops that perform a large number of brake fluid changes daily and aim to streamline this process. The extensive know-how of many years is evident in every detail of the S 30-60. For example, transferring brake fluid is unnecessary. It remains in the original 30 to 60-liter container in which it is delivered; this container is simply inserted into the device.

“That is an important advantage that greatly simplifies the work,” says Werner Rogg. But the Romess engineers also placed great emphasis on easy handling in other respects: two fixed wheels and two caster wheels significantly facilitate the transport of the S 30-60 within the workshop.

After switching on the electrically driven pump, the pressure — which can be continuously adjusted between 0.5 and 3.5 bar — gradually builds up. The advantage of this is that the brake fluid flows slowly and doesn’t foam up. It is pumped into the hydraulic system through an adapter on the reservoir. Due to the pulsating flow of the fluid, vibrations are generated, allowing the brake lines to be fully bled. This is particularly crucial for the functional safety of ABS brake systems.

Conveniently, when the fluid container is down to 1.5 liters, the pump automatically shuts off to ensure no air or air-fluid mixture enters the hydraulic system. However, the remaining amount of fluid in the container is not "lost": during barrel changes, it can be pumped into the new barrel via a bypass switch.

In addition to functionality, Romess places great emphasis on cost-effectiveness. Rogg and his team have also developed ideal solutions for workshops with fewer brake fluid changes: the "smaller brothers" of the S 30-60, the SE 14 and the S 15. Both models are mobile, robust, compact, and economical. For example, the S 15 holds 19 liters of brake fluid, allowing three five-liter canisters to be refilled at a time. A 3.5-meter-long filling hose enables the S 15 to bleed the brake system of a vehicle on any lift. The economic success of this product line speaks for itself: Romess has manufactured and sold 70,000 brake maintenance devices worldwide to date.
