What is the first step after installing an exhaust brake?

The first step after installing an exhaust brake is to measure exhaust backpressure before the brake housing. This measurement is essential because it helps ensure that the exhaust brake is functioning correctly and that the exhaust flow through the system is within acceptable limits. Measuring the backpressure allows a technician to diagnose potential issues that might arise from improper installation or component malfunction.

By checking the backpressure, the mechanic can confirm that the exhaust brake is adequately modifying the exhaust flow as intended, which impacts the engine's performance during braking. This step is crucial for optimizing the vehicle's performance and preventing damage to the exhaust system or engine that could occur if the backpressure is outside the recommended range.

After this initial measurement, further adjustments and evaluations can follow, such as adjusting exhaust backpressure or checking temperatures, but the first measurement is vital for establishing a baseline for the system's operation.
