We can help you with new brake assemblies and the other items needed for maintaining your Haulmark trailer.
I could not find brake specs using the model number but it is easy enough to confirm the details needed. Just pull one of your hubs and measure its drum width and diameter. Please refer to the linked photo. You also need to know your axle weight rating and this can be found on the sticker on the axle itself or on the main trailer sticker that has its VIN. Last you want to note the mounting bolt pattern for your existing brakes; some are 4-bolt, some are 5-bolt. Commonly bigger consumer-grade trailers have 12 x 2-inch drums and use a 5-bolt brake flange.
The linked page displays all electric drum brakes, sorted by axle capacity. Click on your two axles' rating and your drum size to then see suitable brakes. Also click on your wheel (not tire) diameter and select either manual-adjust brakes or self-adjust brakes. Be sure to choose both left- and right-hand brakes. When you wire them, it does NOT matter which magnet wire is grounded or which is hot. Either way works fine.
For new bearings you will need to pull an inner and outer bearing from that hub and the part numbers on them will allow you to easily search our website. Same for grease seals. Our page for those items is linked too.
