Installation Notes
Professional mechanic installation is essential for safety
  1. Ensure vehicle is on level ground - Safely raise and support the vehicle if required
  2. Drain brake fluid - Remove old brake fluid from the reservoir using a clean suction tool
  3. Disconnect brake lines - Carefully disconnect the brake lines from the master cylinder; cap the lines to prevent fluid loss and contamination
  4. Remove the master cylinder - Unbolt the master cylinder from the brake booster or firewall
  5. Bench bleed the new master cylinder - Before installation, bench bleed the new cylinder to remove air and prime the internal chambers
  6. Position the new cylinder - Install the new master cylinder on the brake booster/firewall; hand-start mounting bolts
  7. Torque mounting bolts - Tighten bolts to manufacturer torque specifications
  8. Connect brake lines - Reconnect the brake lines to the master cylinder; torque line fittings to specification
  9. Refill with fresh brake fluid - Fill the reservoir with the recommended brake fluid (DOT 3 or DOT 4 as specified)
  10. Bleed the brake system - Bleed all four brake circuits in the correct sequence (typically furthest from the master cylinder first)
  11. Check for leaks - Inspect all connections for fluid leaks; ensure the master cylinder is not leaking
  12. Test brake pedal - Pump the brake pedal; ensure firm pedal feel and proper pedal height
  13. Road test - Test the brakes at low speed in a safe area; verify proper stopping performance
Quality Control
  • Material Verification: Confirms housing and seal materials meet ISUZU durability and brake fluid compatibility specifications
  • Bore Dimensional Inspection: Cylinder bore diameter, finish, and roundness verified within OEM tolerances
  • Seal Integrity Testing: Each cylinder tested for seal performance and leak-proof operation
  • Piston Fit Verification: Piston fit and movement checked for smooth operation
  • Pressure Testing: Sample tested to ensure consistent hydraulic pressure output
  • Visual Inspection: 100% checked for casting defects, machining flaws, and seal damage
  • Packaged Safely: Protected and packaged to prevent damage during transit
