Little snitch bundle game. Slack adjusters are used to manually (Fig. 51) or automatically (Fig. 53) maintain proper brake chamber stroke and lining-to-drum clearance during normal operation.

Slack adjusters are available in a variety of arm configurations, lengths, torque ratings and spline types.

The entire slack adjuster operates as a unit, rotating with the brake camshaft as brakes are applied or released. The most efficient braking occurs when push rod travel is held to a minimum, therefore it is important that brake adjustments are made often.

Mac manual slack adjuster tools
Rated 4 out of 5 by Jrodeo from Works as it should but could be improvedWorks much better than using an open end wrench and a screw driver but the ratchet could be improved by using a sealed head so grease and grit doesn’t jam up the ratchet mechanism.
Rated 5 out of 5 by dollman0 from Great Brake tool for the ProfessionalSome of the guys laugh at me when I get a new specialty tool off the Matco Truck, but this one is awesome! You need to use a blow gun to get the grease out of the ratchet when you are done, it gets gummed up. Otherwise, this tool set makes easy work of adjusting the square drive slack adjusters, the release tool stays in place to free up your hands.
Rated 5 out of 5 by Prybar9821 from Easy to useTools are easy to identify, which makes for a seemless adjustment on the slack adjuster. You don't have to fumble with a screwdriver and box end wrench. The fork pawl tool holds in place which makes life a little easier.

Rated 3 out of 5 by stevenp from does the job but can see many ways to improveIt has its specific purpose but it hums up very often requires constant cleaning. if it was made into a sealed unit with a flex head locking tool it would be perfected. but overall good tool and get the job done.
Rated 5 out of 5 by Craig from Great ideaNice and easy operation. Ratchet could use a upgrade. I have had a few replaced over the years because of the ratchet skipping. You have to keep the grear cleaned, should be sealed to keep the grease out.
Rated 5 out of 5 by cpost562 from Makes my job much easierThe tool is great for the slack adjusters with the 5/16 square adjuster and is much easier than using a screw driver to open the release pin
Rated 4 out of 5 by thunder87m from A must haveGreat tool for the purpose. Price is high for a tool that only has one use and rarely gets uesd.
