  • Complete seal set tailored for 1-inch bore master cylinders
  • High-grade elastomeric material resists modern brake fluid degradation
  • Restores internal hydraulic pressure and pedal firmness
  • Direct replacement components for simple installation
  • Cost-effective solution to rebuild rather than replace master cylinders
Formulated to rebuild and restore fluid sealing integrity in 1-inch bore GM master cylinders, this comprehensive seal kit includes high-grade elastomeric cup seals, O-rings, and retainers. It restores proper pressure retention within the hydraulic bore, preventing internal leaks and spongy pedal feel in restored original units.
