23431514 GM Brake master cylinder

What is this part?

The GM brake master cylinder 23431514 is a genuine OEM hydraulic braking system component responsible for generating and distributing brake pressure to the braking circuits.

What does it do?

This OEM brake master cylinder converts mechanical force from the brake pedal into hydraulic pressure, which is then transmitted through the brake lines to the calipers or wheel cylinders. A genuine GM brake master cylinder is manufactured to factory specifications, ensuring precise pressure control, internal sealing, and consistent braking response. Proper master cylinder operation is critical for safe, stable, and predictable braking performance.

When to replace

The GM brake master cylinder 23431514 should be replaced if brake fluid leaks, internal seal wear, pressure loss, or pedal fade are observed. Symptoms of failure may include a sinking or soft brake pedal, uneven braking, warning lights, or reduced braking efficiency. Installing a genuine OEM master cylinder helps restore correct hydraulic pressure and overall braking safety.

Compatibility

The genuine GM brake master cylinder 23431514 is compatible with selected GM vehicles equipped with hydraulic braking systems. This OEM component is engineered for correct fitment with the original brake booster and braking circuits. Compatibility may vary depending on engine type, brake configuration, and model year. Please verify the part number 23431514 before purchase.

Installation: DIY or service?

Installation of this genuine OEM GM brake master cylinder 23431514 requires brake system disconnection, proper bench bleeding, and full system bleeding after installation. Professional installation is strongly recommended to ensure correct pressure distribution and safe vehicle operation.
