To Help You C.Y.A. For CSA, We Made Brake Checks
Simple And Fast.

Introducing Our SimpleCheck Air Brake Stroke Tool.

Out-Of-Adjustment Brakes Are A Top CSA Violation.
With SimpleCheck, Drivers Can Check Them And Prevent Them.

With the new Meritor® AllFit SimpleCheck tool, drivers can quickly check air brake stroke. Just one look, and drivers know whether the brake system needs attention, which makes it much easier to run safe and meet Compliance, Safety, Accountability (CSA) and Federal Motor Carrier Safety Administration (FMCSA) regulations. SimpleCheck is easy to install on any cam brake air chamber.

How SimpleCheck Works:

What: SimpleCheck is a green disc used as a marker to visually inspect applied chamber stroke on cam brake-equipped vehicles.

Where: When the brake is fully released, the SimpleCheck disc is installed on the pushrod at the base of the air brake chamber (as shown in image A).

How: When the brake is applied (via service air pressure or parking brake spring pressure), the disc indicates how far the pushrod travels.

Inspection: If the SimpleCheck disc travels less than or equal to the length of the standard 1½-inch brake chamber stud, the pushrod stroke is acceptable (as shown in image B).

If the SimpleCheck disc travels beyond the end of the brake stud (as shown in image C), then further brake system diagnostics must be performed.

It's that simple – and that fast.
