How can one tell if a meritor slack adjuster is no good? Other than the obvious brakes out of adjustment sign. On the bendix ones it should click when backing off correct?
Be easier to just go to Meritors website. They usually have tech info downloadable. For the most part, if you can tighten, but not back off, release the pawl and back off, your good. That doesn't necessarily mean it's doing it's job though. Other factors can influence it's operation
I tried to find the manual can't find one. Pls what other factors can effect the operation of slack adjuster?
Literature on Demand - Product, Technical & Training Information | Meritor Clevis pins should not be frozen or have excessive play. Slack adjuster greased at regular intervals. S cam bushings and brakes should be in good condition. Literature on Demand is free.
I would recommend you look online Volvo repair manuals. My friend managed to solve his problems, there was the necessary information.
The ones with the button type pawl can be bad. The adjuster strips out, or dried grease makes them not function properly. The whole adjuster can be taken out, cleaned, replaced if needed.
