Hydraulic drum brakes use familiar drum components but apply them with brake fluid instead of electric magnets. We diagnose and service the complete system.
Hydraulic drum brakes stop the trailer with brake shoes working inside a drum, much like electric drum brakes. The difference is in how the shoes are applied: hydraulic pressure and wheel cylinders take the place of electric magnets.
That means a complete diagnosis can include the shoes and drums as well as brake fluid, lines, wheel cylinders, and the actuator. Hydraulic drum systems are less common, so we identify the components before ordering the correct replacement parts.
Hydraulic drum service generally runs about $200-$500 more than comparable electric drum brake work. The final total depends on axle size, drum condition, hydraulic components, and parts availability.
These ranges are based on common scenarios supplied by our shop and are not a quote. Parts prices, trailer condition, configuration, and labor can change the final cost.
We verify axle, brake, actuator, and hydraulic component specifications.
We check shoes, drums, cylinders, lines, fluid, and the actuator for wear or leaks.
We install the required parts, remove air from the system, and verify correct operation.
We order hydraulic drum brake components as we use them. Bringing the trailer in allows us to identify the system correctly and avoid guessing at parts.
The braking surfaces work in a similar way, but hydraulic drum brakes use brake fluid and wheel cylinders to apply the shoes. Electric drum brakes use magnets and electrical power.
Because these systems are less common, we generally order their parts as needed after identifying the brake and axle specifications.
A broad planning range is possible, but an accurate quote requires inspection because the issue may involve mechanical brake parts, a leak, lines, cylinders, fluid, or the actuator.
Bring the trailer to our shop for a diagnosis and a repair plan based on the condition we find.
