Left-hand DB-35 disc brake caliper for boat trailer hydraulic disc brake applications. Designed for compatible UFP by Dexter DB-35 brake systems using DB35 hub and rotor assemblies. Important Note : Replacement for UFP (41050LU) DB-35
Compatibility: Designed for compatible UFP by Dexter DB-35 disc brake systems using DB35 hub and rotor assemblies.

Installation Notes: Verify left-hand orientation, rotor compatibility, caliper bracket fit, hydraulic connection, and included components before installation.
Performance Insight: Disc brake calipers apply clamping force to the rotor when hydraulic pressure is delivered from the trailer’s surge brake actuator. The caliper pistons press the brake pads against the rotor to create friction and slow the trailer.
