Finding and Replacing Bri Mar Dump Trailer Parts

If you've spent any time hauling gravel or clearing brush, you know that finding the right bri mar dump trailer parts is the difference between finishing a job and being stuck in the driveway with a dead lift. There's nothing quite as frustrating as getting to the job site, hitting the "up" button, and hearing nothing but a pathetic click. We've all been there, and usually, it's a simple fix if you know which part went south.

Bri Mar has been a staple in the trailer world for a long time. Even though they're under the BWise umbrella now, there are thousands of those classic black and orange trailers still out there working hard every single day. Because they're built like tanks, they tend to outlive many of their individual components. Whether it's a blown seal in a hydraulic cylinder or a wiring harness that's seen too many salty winters, keeping a stash of info on where to get replacements is just good sense.

The Heart of the Machine: Hydraulics

When people go looking for bri mar dump trailer parts, they're usually starting with the hydraulic system. This is what does the literal heavy lifting. Most Bri Mar models use a KTI hydraulic pump, which is pretty much the industry standard for a reason—they're reliable. But "reliable" doesn't mean "immortal."

If your trailer is struggling to lift a load it used to handle easily, you might be looking at a failing pump or a bypass valve that's given up the ghost. Sometimes it's as simple as a low fluid level, but if you see red fluid leaking around the base of the reservoir, it's time to start shopping for a replacement tank or a new seal kit.

The hydraulic cylinder itself is another story. These are the big muscles of the trailer. If you notice "pitting" on the chrome rod or oil weeping from the top of the cylinder, you're losing pressure. Replacing a cylinder can be a bit of a bear because of the weight, but it's a lot cheaper than buying a whole new trailer. Just make sure you match the bore and stroke exactly; getting something "close enough" is a recipe for a structural headache.

Electrical Gremlins and Remotes

It's almost a rite of passage for trailer owners: the moment the remote stops working. You're standing there clicking the button, wiggling the cord, and praying for a miracle. Most Bri Mar trailers use a standard two-button pendant remote. These things get dropped, stepped on, and left out in the rain, so they're one of the most common bri mar dump trailer parts people have to replace.

If the remote is fine but the trailer still won't move, check the solenoid. It's that little cylindrical thing usually mounted right on the pump motor. It acts like a heavy-duty switch. When they go bad, you'll often hear a single click but get no movement. They're cheap and easy to swap out, so I always tell people to keep a spare in the truck's glove box.

And let's not forget the battery. Dump trailers put a massive strain on batteries. If yours isn't a deep-cycle battery, it's going to die a quick death. Many Bri Mar owners eventually upgrade to a dedicated solar charger or a 110V integrated charger to keep that battery topped off between hauls. It saves you from that "click-click-click" of despair when you're trying to dump a three-ton load of topsoil.

Hardware, Hinges, and Tailgates

The "dump" part of a dump trailer puts a lot of stress on the hinges and the tailgate. Bri Mar trailers often feature a "triple-acting" tailgate—you can dump it like a dump truck, spread it like a gravel box, or open it like barn doors. That's a lot of moving parts and a lot of pins that can go missing.

Grease is your best friend here. But even with the best maintenance, those heavy-duty hinges can eventually seize or the bushings can wear thin. When you're looking for bri mar dump trailer parts for the rear of the rig, don't forget the tailgate latches. If they don't snap shut tightly, you're looking at a potential disaster on the highway.

Then there are the "D-rings" and tie-down points. If you're hauling equipment like a skid steer or a mini-ex inside the dump bed, those rings take a beating. If you see a crack in a weld or a ring that's bent out of shape, swap it out. It's not worth the risk of a machine shifting while you're taking a corner.

Keeping the Wheels Turning

We focus so much on the dumping mechanism that we sometimes forget it's still a trailer that has to roll down the road at 65 mph. Most Bri Mar trailers use Dexter axles, which is great news because finding bri mar dump trailer parts for the undercarriage is relatively easy.

Brake assemblies are the big one here. If you've been hauling heavy loads through hilly terrain, those shoes are going to wear down. You can buy the individual shoes and springs, but honestly, most guys just buy the "forward self-adjusting" complete backing plate assemblies. You just bolt them on, connect two wires, and you're back in business with brand-new brakes.

Bearings are another thing you can't ignore. If you haven't repacked your bearings in a couple of seasons, you're playing with fire. If you pull the dust cap and see "milky" grease or metal flakes, it's time for new races and bearings. It's a messy job, but it's way better than having a hub seize up on the shoulder of the interstate.

The Tarp System: Don't Get a Ticket

In a lot of states, if you aren't covered, you aren't legal. Bri Mar trailers usually come with a mounting bracket for a roll-up tarp. Over time, the mesh tarps get shredded by branches or the crank handle gets bent.

When you're looking for a replacement tarp, don't just buy the cheapest one you find. Look for one with reinforced edges and brass grommets. A good tarp should last a few years if you don't overfill the bed and let the material rub against the underside of the fabric. Also, check the tension springs on the arm kits if you have an automatic setup; they tend to lose their "oomph" after a few hundred cycles.

Where to Find What You Need

So, where do you actually go when something breaks? You've got a few options. Local trailer dealers are hit or miss. Some keep a huge inventory of bri mar dump trailer parts on the shelf, while others will just tell you they have to order it from the factory.

The internet has actually made this a lot easier. There are several specialized trailer part warehouses online that have categorized everything by the Bri Mar model number. If you can find your VIN plate (usually on the tongue of the trailer), it makes identifying the specific pump, axle, or cylinder a whole lot easier.

One tip: always check your ground wires first. I can't tell you how many times I've seen someone buy a brand-new $300 hydraulic pump only to realize the real problem was a $5 rusty ground wire making poor contact with the frame. It's the oldest trick in the book for trailers.

Wrap Up

Owning a dump trailer is a huge productivity boost, but it does come with a "maintenance tax." Whether it's a fresh set of hydraulic hoses or a new set of LED tail lights to replace the ones you smashed while backing up, staying on top of your bri mar dump trailer parts list is just part of the game.

Keep it greased, keep the battery charged, and don't ignore that weird squeak coming from the suspension. If you take care of the small stuff, these trailers will easily work as hard as you do for a couple of decades. Just keep a wrench handy and maybe a spare solenoid in the toolbox, and you'll be just fine.
