Detailed Description

This brake master cylinder is engineered for the 2005-2006 Saab 9-2X with front disc brakes and is intended to restore hydraulic braking performance when the original master cylinder shows wear, internal leakage, or inconsistent pedal feel.

What It Helps Fix

  • Soft or spongy brake pedal feel
  • Brake fluid leakage at the master cylinder
  • Uneven or inconsistent hydraulic pressure
  • Pedal travel that increases over time
  • Loss of braking response caused by internal seal wear
