The reservoir is mounted on or near the master cylinder and includes fluid outlets, a sealed cap, and often a fluid level sensor. Its condition directly affects system sealing and braking performance.
A damaged reservoir may cause brake fluid leaks, cracked housing, faulty level sensor readings, air entering the system, soft brake pedal feel, or braking system warnings.
