Brake Fluid Reservoirs for Buses – Safety and Fluid Level Monitoring

Although most modern full-size buses use pneumatic systems, many MIDI-class touring buses and vans based on Mercedes-Benz Sprinter, Iveco Daily and Volkswagen Crafter chassis use a hydraulic braking system. The brake fluid reservoir is a key component in these vehicles: it stores the working fluid and allows its condition to be checked continuously. At Peterbus.pl, we offer durable reservoirs and accessories for buses and vans from Mercedes, Iveco, MAN and Solaris.

The Role and Functions of the Reservoir in the Hydraulic System

The reservoir is not just a container for fluid, but an integrated part of the safety system:

• Fluid storage: Ensures a constant supply of fluid to the brake master cylinder, compensating for the natural wear of the brake pads and the resulting drop in fluid level.

• Level monitoring (sensor): Most reservoirs are equipped with a float integrated with a sensor that immediately informs the driver of a leak or excessive lining wear.

• Contaminant separation: Special screens beneath the cap prevent dust and dirt from entering the system when fluid is being topped up.

• Venting: Reservoir caps feature pressure-equalising valves, preventing the formation of a vacuum that could block fluid flow.

Why Replace the Reservoir with a New One from Peterbus.pl?

Over time, the plastic from which the reservoir is made may age and become brittle or discoloured, making it impossible to check the fluid level visually. By choosing our parts, you benefit from:

1. Chemical resistance: Our reservoirs are made from plastics resistant to the aggressive effects of DOT 3, DOT 4 and DOT 5.1 brake fluids.

2. Full leak-tightness: We offer reservoirs precisely matched to the brake master cylinder mounting points, eliminating the risk of leaks at the seals.

3. VIN-based selection: Reservoirs differ in shape, capacity and the number of connections, for example for the clutch system. Our experts will precisely select the right model for your vehicle.

4. Safety and approvals: We offer products that meet OEM standards, ensuring correct operation of the level sensors and preventing false warnings on the dashboard.
