Meritor R805005 is an automatic slack adjuster (ASA) for drum brakes, built with a 5.50 in. arm and a 1.50 in. slack spline with 28 splines. It is an unclevised Type 1 unit with a 0.50 in. bushing inside diameter and a yellow extended-lube piston, and it senses brake stroke to decide when to adjust.
An automatic slack adjuster takes up the free play that builds as brake linings wear, so brake stroke stays consistent without hand adjusting. Chamber sizes 24 or 30 are listed for this unit. It is a genuine Meritor part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
