2009 Mercury Mariner Wheel Cylinder Parts Questions & Experts Answers

• Q: How to properly bleed a wheel cylinder to maintain braking performance and prevent system contamination on 2009 Mercury Mariner?

  A: When bleaching wheel cylinders professionals should exclusively use new brake fluid compliant with manufacturer standards because spoiled brake fluid can cause system contamination and damage to the system. You should maintain a proper fluid level in the brake master cylinder throughout this procedure or else you will risk damaging the components and negatively affect braking ability. Any occurrence of brake fluid release on paint or plastic needs immediate water cleaning of the affected surface. A brake system bleed is not required when only the wheel cylinder needs replacement or disconnection. Begin with bleeder screw cap removal and install a box-end wrench on the bleeder screw. You should connect a rubber drain hose to the bleeder screw with the hose end submerged in a brake fluid container. The assistant should pump the brake pedal two times followed by maintaining firm pressure on it during the procedure. The assistant should maintain pedal pressure while you loosen and retighten the brake fluid bleeder screw which allows controlled fluid stream escape. Repetitions of the bleeder screw operation will result in clear bubble-free fluid so the reservoir requires refilling when necessary. Following the specified torque value on the bleeder screw users should remove its rubber hose before installing the bleeder screw cap. Carry out brake tests several times to verify their correct functioning.
