thanks for helpful vid. hey, just to clarify for future viewers, 1 full turn is 360 degrees; 1/2 turn is 180; 1/4 turn is 90. So after tightening the adjuster, we back it off 1/4 turn.

You need to also state a good brake system will never have to be touched after rebuilding a brake system.Also everytime you manually adjust the slack adjuster you are wearing the lock out.That is why A BRAKE THROW CHECK SHOULD BE THE ONLY CHECK DONE, THEN THE SLACK ADJUSTER SHOULD BE DONE IF THE THROW IS OUT OF SPEC.Lastly IF ANYTHING IS OUT the slack adjuster, s cam and chamber should be inspected for wear or damage.

@@apacheone3643 i agree about them being too old, but there are still a lot out there with manual slack adjusters. Tbh, they are not bad as long as they are adjusted right. The adjusting them is a pain and that is why a lot of drivers didn't do it and started crashing, so they came up with auto slack adjusters, which are really not any more safe than regularly adjusted manual slack adjusters, but less hassle and since drivers weren't adjusting the manual adjusters they seemed safer. The problem now is that too many drivers take auto slack adjusters for granted and do not really check them so when they eventually fail, driver either crash or hopefully get put out of service before they crash. Disk brakes are definitely the best if all 3, but come with the problem of either being difficult/nearly impossible to check, on a daily basis, or take a full class to figure out how to check them.

@@Bendigo1 There is no adjustment on Disc brakes or a Slack adjuster. The Calipers adjust themselves the chamber bolts DIRECTLY TO THE CALIPERS. I have been working with them 8 plus years. My favorite are the Mertor brakes they are superior in the size of the pad Calipers have a long life as long as they are not abused or rebuilt inproperly.. I have had a rebuilder screw up 6 sets of Calipers I video tape a brand new out of the box Caliper and sent it to the rebuilder. As far as drivers not taking care of the brakes you find that more on the privates than in the over the road company's(OTRC) . The OTRC cut corners else were like Transmissions and Engine maintenance.. The saying goes pay me now or pay me later.
