The ProVia ProVia Single Brake Chamber (part number PRO7140330) is a replacement component for the air brake and air suspension systems of heavy-duty trucks, buses and semi-trailers. It is built to original equipment specification from quality materials, so it installs on the original mounting points and performs reliably throughout the service life of the vehicle. Key ratings include Max Working Pressure 13 bar, temperature range -40°C ~ +80°C, Stroke 57.1 mm, push‑rod length 235 mm, clamp band diameter Ø212 mm.
The single-diaphragm design converts air pressure into a strong, linear push-rod force for the service brake, with no parking spring, which keeps the unit light and simple. The internal breathing valve prevents moisture build-up and protects the diaphragm for a long, trouble-free service life.
Every unit is manufactured to original equipment specification and inspected before it leaves the factory, so it matches the fit, function and durability of the original part. Sealed, vibration-tested construction keeps performance stable in the heat, dust, road salt and constant vibration found on commercial vehicles, and standard interfaces make installation and maintenance straightforward. Spare parts, technical data and fitting advice are available on request.
