R&P Knowledge Hub
Hydraulic drum brake assemblies use wheel cylinders to apply force to the brake shoes when pressurized fluid is delivered from the master cylinder. Duo-servo designs allow both shoes to contribute braking force under load conditions.
Forward self-adjusting mechanisms maintain proper shoe-to-drum clearance as lining material wears. Confirm brake diameter, brake width, bolt pattern, axle rating, and correct left or right orientation before installation.
