What distinctive feature identifies long stroke brake chambers?
- Them having longer brake lines
- Them having square-shaped inlet ports ✓
- Them being generally larger
- Them having a different color
Answer: B. Them having square-shaped inlet ports
Long stroke brake chambers are identified by their square-shaped inlet ports.
Why this is the answer
The handbook describes long stroke chambers as having a longer pushrod stroke than standard chambers. It then gives identifying features: the inlet ports are square-shaped, and there may also be a trapezoid-shaped name tag on a clamp bolt. That identifying detail matches the square inlet ports. The other listed features in the choices are not mentioned as identification marks for long stroke chambers.
Why the other answers are wrong
- A. Them having longer brake lines — Longer brake lines are not given as an identifying feature; the handbook points to the chamber's inlet ports and name tag instead.
- C. Them being generally larger — Being generally larger is not stated as the way to recognize a long stroke chamber; the passage focuses on pushrod stroke and inlet port shape.
- D. Them having a different color — A different color is not mentioned; the handbook names square inlet ports and a trapezoid name tag as identifiers.
Remember it
Picture a square inlet port as the stamp that marks a long stroke chamber.
