What should be measured after installing an exhaust brake?

• A. Adjust the intake and exhaust valves.
• B. Measure the exhaust system temperature.
• C. Measure exhaust backpressure before the brake housing.
• D. Measure exhaust backpressure after the brake housing.

Answer: (D)

After installing an exhaust brake, it is crucial to measure the exhaust backpressure after the brake housing. This measurement is important because it helps evaluate how effectively the exhaust brake is functioning. The backpressure created by the exhaust brake can affect engine performance and efficiency. By measuring it after the brake housing, you can assess the brake's impact on the exhaust flow and ensure that it is operating within the designed parameters. If the backpressure is too high, it may indicate a blockage or inefficiency in the exhaust system, which could lead to performance issues or engine damage over time. This measurement allows technicians to confirm that the exhaust brake is doing its job without causing excessive strain on the engine. The other options focus on aspects that are not directly reflective of the exhaust brake's effectiveness after installation, making them less relevant in this context. Adjusting the intake and exhaust valves is typically part of routine engine maintenance, while measuring temperatures and backpressure before the brake housing do not provide the necessary information about the brake's performance.
