2008 Chevrolet Corvette Brake Master Cylinder

The procedure is to remove the brake master cylinder from the vehicle, secure the mounting flange of the brake master cylinder in a bench vise so that the rear of the primary piston is accessible, clean the outside of the master cylinder reservoir on and around the reservoir cap prior to removing the cap and diaphragm, remove the reservoir cap and diaphragm from the reservoir, inspect the reservoir cap and diaphragm for the following conditions, remove the master cylinder reservoir from the master cylinder, depress the primary piston and remove the piston retainer, remove the primary piston assembly from the cylinder bore, plug the cylinder inlet ports and the rear outlet port and then discard the primary piston assembly, the piston retainer, and the seals and seal retainer from the secondary piston.

The recommended torque is 29 N.m (21 lb-ft).

The procedure is to disconnect the electrical connector from the brake fluid level sensor, disconnect the brake pipes from the master cylinder, plug the open brake pipe ends, remove the master cylinder mounting nuts, remove the master cylinder from the vehicle and then drain the master cylinder reservoir of all brake fluid.

The procedure is to inspect the brake fluid level through the brake master cylinder reservoir. If the brake fluid level is at or below the half-full point during routine fluid checks, the brake system should be inspected for wear and possible brake fluid leaks. If the brake fluid level is at or below the half-full point during routine fluid checks, and an inspection of the brake system did not reveal wear or brake fluid leaks, the brake fluid may be topped off up to the maximum-fill level. If brake system service was just completed, the brake fluid may be topped off up to the maximum-fill level. If the brake fluid level is above the half-full point, adding brake fluid is not recommended under normal conditions. If the brake fluid is to be added to the master cylinder reservoir, clean the outside of the reservoir on and around the reservoir cap before removing the cap and diaphragm.

The procedure is to bench bleed the master cylinder, install the master cylinder to the brake booster, install the master cylinder mounting nuts, connect the brake pipes to the master cylinder and then connect the electrical connector to the brake fluid level sensor.
