How to Bleed the Master Cylinder on a 1988 Chevrolet Beretta

Any work performed on a brake master cylinder will cause air to enter a vehicle's entire brake system. This results in spongy, ineffective brakes, and you need to "bleed" the air out. Bleeding a master cylinder on a Chevrolet Beretta is much like bleeding the brakes on any other vehicle. You need to bleed the air out at each of the four brakes, as the master cylinder will send the air through the entire system.

Tools Used: DOT 3 brake fluid, Floor jack, Jack stands, Tire iron, Clear hose, Bottle, Wrench, Assistant

Bleed Master Cylinder

Fill the brake master cylinder's reservoir with fresh DOT 3 brake fluid to the maximum level and close the cap on the reservoir.

Raise the Beretta on both ends and support it on jack stands. Remove the right (passenger side) rear wheel.

Connect a rubber/vinyl hose (preferably a clear one) to the bleeder valve on the wheel cylinder. Submerge the other end of the tube in a small bottle partially filled with brake fluid.

Loosen the bleeder screw with a wrench as your assistant presses down on the car's brake pedal in the driver's compartment. Look for a mixture of fluid and air to come out the tube, then close the screw once it stops flowing.

Repeat the previous step until fluid comes out of the tube cleanly with no air. Tighten the screw and reinstall the wheel.

Inspect the brake fluid level in the cylinder reservoir. Add more if it is noticeably low.

Repeat the bleeding process for the left rear wheel, followed by the right front wheel and the left front wheel.

Refill the reservoir as needed and lower the car off the jack stands.
