Dealing with brake issues?
This ACDelco Professional master cylinder is exactly what you need for a reliable repair.

It comes ready to install right out of the box - already bench bled so you can skip that messy step.

The construction uses both aluminum and iron castings that distribute stress properly without putting extra strain on your brake booster mounting.

Inside, the EPDM and SBR rubber components provide superior resistance to heat, corrosion, and potential leaks that can compromise your braking system.

The geometrical tolerance ensures the body and plastic reservoir match up perfectly for a proper fit without any modifications.

The piston assembly and return spring work together to prevent brake drag, which means your brake pads will wear more evenly and last longer.

It's been pressure tested to ensure safe, confident braking performance that meets SAE J1153 and J1154 standards.
Installation is straightforward if you're comfortable with brake work - uses the same mounting points as your original equipment.

Whether you're a DIY mechanic or professional technician, this master cylinder delivers the quality and reliability you expect from ACDelco Professional line.

Your brakes are literally the most important safety system on your vehicle, so don't compromise - this component gives you peace of mind that your stopping power will be there when you need it most.
