Abstract
Systems and methods for brake cable adjustment are disclosed herein. In this regard, a gage block tool for adjusting a brake cable may comprise a body comprising, a first member extending in a first direction, the first member having a first length and a first thickness, and a second member extending in a second direction, the second member having a second length and a second thickness. At least one of the first member or the second member may be sized and configured to be placed between a stop and a lever of a brake valve, the brake cable connected between the lever and a brake handle being properly adjusted when the gage block sandwiched between the lever and the stop contacts both the lever and the stop while the brake handle is in a park lock position.
Claims18
A gage block tool for adjusting a brake cable comprising:
- a body comprising:
- a first member extending in a first direction, the first member having a first length and a first thickness;
- and
- a second member extending in a second direction, the second member having a second length and a second thickness,
- wherein at least one of the first member or the second member are sized and configured to be placed between a stop and a lever of a brake valve, the brake cable connected between the lever and a brake handle being properly adjusted when the gage block sandwiched between the lever and the stop contacts both the lever and the stop while the brake handle is in a park lock position.
A system for brake adjustment comprising:
- a brake valve having a lever and a stop;
- a brake cable operatively coupled to the lever;
- a brake handle;
- and
- a gage block tool for adjusting the brake cable, comprising:
- a first member extending in a first direction, the first member having a first length and a first thickness;
- and
- a second member extending in a second direction, the second member having a second length and a second thickness,
- wherein at least one of the first member or the second member are sized and configured to be placed between the stop and the lever of the brake valve, the brake cable connected between the lever, and the brake handle being properly adjusted in response to the gage block tool, sandwiched between the lever and the stop, contacting both the lever and the stop while the brake handle is in a park lock position.
A method for adjusting a brake cable comprising:
- placing a gage block between a stop and a lever of a brake valve;
- moving a brake handle connected to the lever by a brake cable to a park lock position;
- and
- adjusting the effective length of the brake cable such that the stop and the lever both contact the gage block,
- wherein the adjusting the effective length of the brake cable is in response to at least one of:
- the lever contacting the gage block before the brake handle has reached the park lock position, or
- the brake valve lever not being in contact with the gage block in response to the brake handle being moved to the park lock position.
