Hydraulic brake systems rely on fluid to transfer force. Leaks could lead to reduced braking efficiency.

Extended or heavy braking can cause overheating and reduce braking power.

Air bubbles in hydraulic brake lines can cause a spongy brake pedal and reduced braking performance.

A malfunctioning brake booster can result in a hard brake pedal and reduced braking assistance.

Regular wear and tear can lead to diminished braking performance and increased stopping distances.

V-shaped engines with multiple cylinders, like the L5P, can experience misfires due to ignition or fuel delivery issues.

Direct Injection (DI) systems can suffer from clogging or failure of fuel injectors, affecting performance and fuel economy.

If equipped, turbochargers in Duramax engines can encounter issues such as oil leaks or bearing failures.

Diesel engines often have complex emissions control systems (e.g., DPF, EGR) that can fail or become clogged.

Issues with the cooling system, such as radiator or water pump failures, can lead to engine overheating.

Modern engines with advanced electronics can encounter problems with sensors, wiring, or control modules.

Diesel engines are particularly sensitive to fuel quality, and contamination can cause extensive damage.

The DPF can become clogged, leading to reduced engine performance and increased emissions.

Over time, the timing chain or belt can wear out, leading to potential engine timing issues and failures.
