Reliable Mfg: Trailer Brake, Axle and Suspension Components

Reliable Mfg offers a focused range of replacement hardware for trailer running gear. The products carried under the Reliable Mfg name cover the parts that keep a trailer stopping, tracking and riding the way it should: hydraulic brake assemblies, axle tie plates, U-bolt kits, leaf spring hangers and the fasteners that hold it all together.

Hydraulic Brake Assemblies

Trailer brakes take a beating from heat, road spray and heavy loads, and complete brake assemblies are a straightforward way to refresh a worn axle end. The Reliable Mfg lineup includes right-hand hydraulic units such as the HBRH-1000, a 10" x 2-1/4" assembly, and the HBRH-1200 Uni-Servo, a 12" x 2" assembly. Hydraulic brakes are commonly paired with surge-style actuators on boat and utility trailers, so it is worth confirming your actuation type before ordering. Drum diameter and width, axle capacity, and left-hand versus right-hand orientation should all match your existing setup.

Axle Tie Plates and U-Bolt Kits

The connection between axle and leaf spring is one of the most stressed points on any trailer. Tie plates and U-bolts clamp the axle tube to the spring pack, and they need to match the axle shape and size precisely. Reliable Mfg offers tie plates for both square and round axles, including the TP-S-220 for square axle and the TP-R-370 for round axle, along with the 3011 U-bolt kit sized for 2" square tube trailer axles. When replacing these parts, check axle dimensions, spring width and U-bolt diameter, and replace hardware as a set rather than reusing stretched or corroded pieces.

Spring Hangers and Lock Nuts

Tandem-axle trailers rely on sturdy hangers to locate the springs and equalize load between axles. The HG-105 rear weld leaf spring hanger is designed for tandem axle trailers and is welded to the frame. Fasteners matter just as much: the FLN-437 flange lock nut in 7/16-20 thread provides a wide bearing surface and resists loosening from road vibration.

What to Consider When Shopping

• Axle type and size: Square and round axles use different tie plates and U-bolts.
• Brake specifications: Match drum size, hydraulic or electric actuation, and side of the trailer.
• Spring configuration: Single versus tandem setups call for different hanger styles.
• Hardware condition: Replace nuts, bolts and U-bolts whenever the suspension is disassembled.

Whether you are restoring an older utility trailer, maintaining a boat trailer that sees regular water exposure, or repairing a cargo hauler, Reliable Mfg parts cover several of the wear items that come up most often in trailer upkeep.
