    4 wheel brakes on boatmate anyone?

    I just bought the trailering arm assemblys, instead of changing a blown grease seal going to go four wheel brakes to hopefully fix another issue of locking brakes on harder stops, Tom recommended I go this route. Has anyone done this? I would like to hear how you connected the brake lines. I was thinking a tee on both sides to coated steel lines to the next axle then rubber to calipers.
    I flat spotted two sets of tires already

    Mine is a 4 wheel brake setup, ordered it that way. I have a wheel off right now so I will take a pic of it when I get home this evening so you can see how Boatmate plumbs it.

    Ball height or equalizers might be the issue. Not enough weight on the brake axle?

    Mike its some known issue going on I talk to Boatmate last year they were going to send me a orifice or something to prevent lock up , of course it never came and they have zero customer service no return calls nothing.

    Mine was locking up in reverse, had to put the fuse from the truck in a tester to find out it was bad, haven't had any issues in forward, 2016 Boatmate 21RDC

    Here are a couple pics, the front caliper hose goes directly to the rear caliper. I need to get my shop light out so you can see it better. It doesn’t have 2-3 tees like you might think it would, instead both calipers on each side are plumbed off each other.

    I got 4 brass connectors you put a banjo bolt through, I guess I am short long rubber lines , can I trouble you to measure the rubber line from front caliper to rear?

    Sorry for a delayed reply, worked late all last week and was out fo town this weekend. The hose from rear to front caliper measure out to 46-48”. It is straight for 36” then the radius to each caliper is roughly 5-6” each end. Don’t get anything shorter than 48 and you will be fine. Now my trailer is torsion axle and not leaf spring so there could be some difference between those. Mine actually has a little more slack at the back caliper so I would assume they use the same hose for either axle style.

    towed for first time with 4 wheel brakes , wow big difference I highly recommend adding the second set of calipers. Everything was bolt on and quick to install. I spent about $600. Not to mention I painted the calipers red they just look sweet.

    Mine was bad about locking up when I had it. That was a 2018 trailer. Went through 2 tires.
