⚠️ Common Signs of Failure

• Fluid weeps through the braid or fittings
• Braid is frayed, crushed or kinked
• Hose rubs on the chassis or tyre
• Fittings are corroded or rounded
• Brake pedal/actuator pressure feels soft because air enters the circuit

• Fit new copper washers on banjo connections
• Do not twist the hose while tightening
• Bleed and pressure-test the system after installation
