    It's a stupid cat and mouse game that you cannot avoid or win by doing all the right things. A crumb was found on the counter and you were seen leaving the kitchen! So you received a WARNING. Today, you get scrutinized for just being. To survive and not be driven absolutely bonkers you must learn to play their game. They want you in defense mode, don't go there, let it roll off your back like it didn't happen. No need to let them create some unnecessary work and expense for you, as if you don't have enough of that already.

    no one pulls wheels and drums to visually inspect.

    just because FL inspected 30 days ago doesn't mean something couldn't happen 30 days later.
    a lot of it depends on the drivers braking habits also.

    i just had a hub and lining replacement 2 days ago. on one axle. the pads were cracked into sections at the rivets. not on the outside. but on the inside. i'm in a loaner truck. and the jakes aren't that great.

    why are you replaceing all your securement equipemtn. and why are you getting into so much trouble????
    chains don't wear out. binders only replace when they wear out the pivot pins. straps only replace when they get more then 3/4 inch tear, as was told by scale.

    keep your equipment clean, dash clean, and loads secured so that dot smiles as your roll across the scale. there shouldn't be any problems.

    we have drivers that refuse to be neat. they constantly get put out out of service.
    only time i get stopped, is by the policeman. and usually drive away with a clean lvl 3.

    1/16" you are allowed IIRC . That's also max gap allowed for shoe to lining.

    Good trick is to put a dab of silicone in crack and then run finger in nearby brake dust and dab dust onto wet silicone to camouflage it. Heh, heh, hee!

    Understand what you are saying snowwy, but that is NOT the case here, there were two DOT guys checking out the truck and trailer, even commented on how sharp the truck was.

    As I said, trailer is all Alum. two months old, you can see yourself in the reflection, all alum. wheels and tanks, ALL polished out!!!

    We DON'T run crap equipment!!! As far as straps go, we have gone to a different type strap, over the tire rather than side mount, we also used to have strap on the ends of the ratchets that would rub and fray on the rub rail, we have replaced all of those with chain ends so no more frayed straps.

    When he gets in here tom. I will post some pics, my rigs get compliments every where they go. This driver is also WELL kept, no beard, well dressed, not a smart arse, he been with me over 7 years.

    There is no regulation or standard as far as cracks go. As long as it meets thickness and performance standards it's suppose to be suitable.

    On the other hand all defects and deficiencies that might effect the safe operation of a vehicle are suppose to be reported and corrective action taken.

    If it's broke at a rivet or separating from a shoe it could be determined defective and could fall apart.

    Like others said unless there is obvious damage when looking from underneath I wouldn't worry about it.

    How could that part be miscontrued? Some deranged LEO might say it's not continuous if on a steer axle. :)

    Deranged LEO? Hey, that's ME!!!:biggrin_25524:

    As for as Kansas Transit's original question, "is there ANY allowance for hairline cracks when looking at the side of brake pads?", actually, there are specific criteria for brake linings and cracks, it is found in the CVSA Out of Service Criteria. A copy of last year's version is found here:http://www.tn.gov/safety/CVE/NorthAmericanStandardOut-Of-ServiceCriteria.pdf. The brake lining criteria is the same for this year.

    For brake linings on an axle other than steering axle, the following would be defective brakes:
    Defective lining conditions.​
    i. Lining cracks or voids that exceed 1/16 inch (1.6mm) inwidth observable on the edge of the lining. (393.47(a))
    ii. Portion of a lining segment missing such that a fastening
    device (rivet or bolt) is exposed when viewing the liningfrom the edge. (393.47(a))
    iii. Crack that exceeds 1-1/2 inch (38.1mm) in length.
    (393.47(a))
    iv. Loose lining segment. (Approximately 1/16 inch (1.6mm) or
    more movement.) (393.47(a))
    v. Complete lining segment missing. (393.47(a))

    vi. The friction surface of the brake drum and the brake
    friction material are contaminated by oil or grease.(393.47(a))
    vii. Lining thickness less than 1/4 inch (6.5mm) or to wear indicator if lining is so marked, measured at the shoe

    center. (393.47(d)(2))
    Pretty much the same thing for steering axle with different thickness limits.

    Ok, here are the pics as promised. As you can see in the pic, yes the shoe is cracked and yes, I did have it replaced, and I had Freightliner do it just so I had a paper trail.

    When I questioned the mechanic about this shoe (all the rest checked out) he rolled his eyes and said something to the effect of %^&&* over efficient ^&*(&& jerk !!!!

    He said in his opinion ( and he made sure that I knew he has been a truck mechanic for 18 years) that this was a non-issue and that he would bet it would have never created a problem.

    Also I included pics of the trucks and trailer, you can see they are not crap equipment. I guess draw from it what you will,

    Thanks

    Stan

    Looks like it could be over 1 1/2 long and maybe even over 1/16 wide.

    I should have taken a pic with ruler 1 1.25 long, not close to a 1/16.
