The adjuster incorporates a clutch release and has improved corrosion protection, both of which increase the life span of the adjuster, the company said.

According to Terry Mennen, vice president, sales and marketing, MVS Commercial Vehicles, the company’s new GEN II model is easy to install and to manually adjust the proper shoe-to-drum clearance.

“We wanted to improve the effective working life of our products, so we looked at the areas most likely to cause early failure,” he said.

The major area of improvement is that the unit enhances the life of the clutch. The clutch is the key wear component in the brake adjuster. Every time a manual adjustment is made as a part of brake maintenance, additional wear occurs, impacting clutch life, the company said.

MVS Crewson said it addressed this issue with a clutch release feature called Spin Guard that allows manual brake adjustment to occur without damaging the clutch. The result is a longer life product, the company said. The adjusting shaft hex can turn freely in either direction when Spin Guard is used, which means no more “hard” one-half turn backoffs to preset lining-to-drum clearance, the company said. Installers need only push in the Clutch Release Button, back off the hex one-half turn and release the button.

Corrosion has been a perennial problem for all undercarriage components, according to Mennen. Corrosion-resistance on the GEN II is improved with the use of Crewson’s patented ”Cam-Guard” feature, which protects the S-Camshaft splines by guiding grease to the splines every time the ABA is greased, he said.
