What condition may lead to excessive wear on the engine brake system?

Excessive slave piston travel can lead to excessive wear on the engine brake system because it indicates that the components are moving beyond their intended range. When the slave pistons travel too far, it can cause the brake pads to make prolonged contact with the braking surface, which creates undue friction and heat. Over time, this excessive friction results in accelerated wear of the brake components, including the pads, rotors, and potentially the slave piston itself. Additionally, this could result in overheating and damage to the surrounding components, leading to a reduction in overall braking efficiency and increased maintenance costs.

A well-functioning engine brake system relies on precise adjustments and proper piston travel to ensure effective operation. By maintaining the correct specifications, wear can be minimized, which enhances the lifespan and reliability of the braking system.
