Exhaust Brake

Exhaust brake for buses – Safer descents and reduced wear on the braking system

The exhaust brake is an essential component in every bus, enabling effective deceleration without using the service brakes (disc or drum brakes). The system works by restricting the flow of exhaust gases in the exhaust system with a special flap, creating back pressure and slowing the movement of the engine pistons. This allows the driver to negotiate long descents safely while avoiding overheating of the brake discs, known as brake fade. At Peterbus.pl, we offer complete exhaust brake mechanisms and replacement parts for buses from Solaris, MAN, Mercedes-Benz, Scania and Volvo.

Engine brake system components in our range

We provide access to control and actuating components installed in the exhaust system:

• Exhaust brake valves and flaps: Robust flaps installed on the exhaust manifold or exhaust pipe, resistant to extremely high exhaust gas temperatures.

• Pneumatic exhaust brake actuators: Actuating components that physically close the flap when the driver presses the button or pedal.

• Control solenoid valves: Components responsible for precisely supplying air to the exhaust brake actuator.

• Repair kits and seals: Rings, bushes and springs that allow seized flap mechanisms to be reconditioned.

Why is a fully functional exhaust brake so important?

Regular use of the engine brake is not only a matter of safety on mountain bends, but above all a real saving for the operator. By choosing parts from Peterbus.pl, you benefit from:

1. Longer pad and disc life: The exhaust brake absorbs a significant part of the braking energy, which can extend replacement intervals for friction components by up to two times.

2. Protection against engine cooling: A correctly functioning system helps maintain the engine’s optimum operating temperature during long descents without load.

3. Selection by VIN: Exhaust brake mechanisms differ in exhaust pipe diameter and control type (pneumatic or electric). Our specialists will select a part that fits your power unit perfectly.

4. Reliability in Euro 5 and Euro 6 systems: We offer flaps compatible with modern exhaust after-treatment systems (DPF/SCR) that do not interfere with the operation of exhaust pressure sensors.
