    Default Adjusting Run in Brake

    Hey everyone,

    Iíve got a BL Miskruier Iíve been using for 6+ years. Itís a great van, but Iíve never been a huge fan of the run in brake system. It used to actually engage the brake, but for years now, it has just slammed into the trailer hitch when slowing down off-road or braking hard. Iíve adjusted the brake cables so that the wheels stop at the same time, Iíve greased the large ram type piston plenty, but still nothing changes. Iím at a loss for what to do. A couple years ago when I was down in Centurian, I had the caravan serviced and some mods/repairs done. They verified that the run in brake was fine. Still, it doesnít brake, but rather transfers the weight of the caravan during braking onto the tow hitch with a might ĎBAM!í...

    Any help or tricks on adjusting it would be appreciated.

    I would also say that shock has been shot for years. Have you tried pushing it in and out. If it moves easily then you have found the problem.

    Iíve not. Iíll check today. What is the expected life span of a tow bar shock? How often should I replace it? I tow that caravan off-road between 2-4 times a month depending on the month.

    I had the same problem. Took it for Roadworthy and it just failed. Ask the same question, got the same reply w.r.t. the shock absorber.
    Replaced, bought from Al-Ko directly, problem gone and Roadworthy Certification gained.

    Cheap-ish if I remember correctly.

    I took mine off and went to Al-Ko to get the correct replacement unit.

    So, the shock is definitely not the problem. When engaging/disengaging the hand brake, I thought it was quite firm. Still, I removed it to check. That thing was very stiff. It took me 2 hrs with two other men, a ratchet strap, pry bars and a lot of ingenuity to get it back in place... What a pain. Any other ideas? If the borders were open, Iíd just cross over to Namibia and have it fully serviced along with some mods done, but as Angola hasnít reopened itís borders for normal travel yet, Iíll have to wait on that.

    So, Iíve yet to tow for testing purposes, but after doing the adjustment per video, my handbrake is perpendicular to the coupler. Itís not been like this in more than 5 yrs.

    I am importing a redarc brake controller along with hydra star hydraulic brake and brake away and switch etc etc.

    But mine is for a heavier application. My problem now is to find a coupler rated above 750kgs (looking for 3500kgs rating) with no overrun mechanism.

    Nice video of brake adjustment.

    I battled with my one trailer and googled for info. I did everything except remove the nuts, I just loosened them.

    great video.

    Hey Peter, thanks for the reply. Unfortunately what would seem to be an easy option in RZA and Namibia is not an option in Angola. To further complicate things, Iíd have to drive 2 days and cross an international border, which incidentally has been closed for the past year...

    Ok, this is what works for me. I have 6 brake drums on my trailer.

    Make sure that all bearings are pulled up to about 5nm, or minimum play.

    Adjust the play, on the back of the drum until you hear the shoes touching the drum. Then 90deg back.

    No go to the rod and make sure that is not to tight. It must have free play.

    Then take that trailer out on the road and watch your mirrors, for any wheel lockups. Also stop after some time and feel that any heat buildup on the drums, are the same on all drums.

    PS. I just want to add here.
    When packing the bearings. When fitting new bearings, please don't torque down on those bearings. You will damage them.

    To get them to bed, use a piece of mild steel. Punch with the rod around the bearing to get it to bed properly. The reason why you use the mild steel, is that it is so much softer than the bearing shell. Then fit the bearings and torque to 5nm. Then drive it for a bit and go back and check that those bearings haven't developed any new play. If they do, you didn't bed them properly. So then redo the free-play to 5nm.

    Also don't over-pack the bearings.

    PPS. I use a normal grease, with a squirt of Uniglide in ea bearing.

    This sounds like you removed the spring that loads the handbrake, not the shock/damper. The damper is inside and is usually accessed by removing the tow hitch. I can fit a new one by just pulling the hitch as far forward as it goes, then inserting the bolts that hold the damper.

    I'm not sure what chassis you have but this manual might help:

    Thanks for the link. That’s a really good PDF for ALKO product maintenance/adjustment procedures. Would be great to pin that somewhere on this forum for others to use.

    So my coupler is made by Knott. I’ve not seen any shock/damper anywhere on the coupler. I figured there’d be sort piston/ram on the run-in side of the coupler, but have never seen it personally. If anyone knows of a good illustration for KNOTT couplers, I’d greatly appreciate you posting it.

    EDIT: So your post about removing the wrong shock got me thinking. First, the hand brake “spring” on a Knott coupler looks like a shock to me, so it was the first place I went. Second, looking inside never occurred to me as I’ve not yet seen any diagram as to how it works. So, I gave the couple a good push, and it resists any force I put on it. It will slowly give under pressure, but it’s not pushing in and out like a damaged/worn out shock might do. This leads me to believe that it may just have been poorly adjusted brakes. Still, next time I’m in Namibia, I may purchase one of these run-in brake shocks as a spare.

    Thanks for the tip Henris. Iíll keep that in mind when I check my wheel bearings. I generally check the wheels and hubs whenever I stop the car, especially when Iím airing up or down. Just a force of habit.
