A brake master cylinder reservoir is a component of the braking system designed to store brake fluid and supply it to the master cylinder. It helps maintain proper hydraulic pressure and compensates for fluid level changes caused by brake pad wear.

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.

genuine factory reservoirs
