Built as a direct replacement-style component, this DFC rear brake wheel cylinder supports a straightforward installation when paired with properly serviced brake shoes, springs, lines, and hardware. Replacing a compromised wheel cylinder can help address fluid leakage, uneven braking, reduced pedal performance, and contamination of the brake linings. Professional installation and complete brake-system inspection are recommended to ensure safe operation and proper adjustment.
This automotive replacement part is sold individually and is identified by DFC part number DFC375-48000. It is intended for compatible rear drum brake applications on the listed Chevrolet and GMC trucks. Because classic vehicles may have received brake-system changes during prior repairs or restoration, confirm the existing wheel cylinder and application details before ordering.
