2008 Cadillac XLR Brake Master Cylinder

You should remove the master cylinder reservoir cap and diaphragm, install suitable fittings to the master cylinder ports that match the type of flare seat required and also provide for hose attachment, install transparent hoses to the fittings installed to the master cylinder ports, remove the transparent hoses from the master cylinder reservoir, install the master cylinder reservoir cap and diaphragm, and remove the fittings with the transparent hoses from the master cylinder ports, and the master cylinder from the vise.

You should bench bleed the master cylinder, install the master cylinder to the brake booster, and the master cylinder mounting nuts, remove the plugs from the brake pipes, connect the brake pipes to the master cylinder, connect the electrical connector to the brake fluid level sensor, and bleed the hydraulic brake system.

You should 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, and 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.

You should assemble the lubricated, new primary seal and retainer, and new secondary seal onto the secondary piston, and install the lubricated return spring and secondary piston assembly into the cylinder bore, the lubricated, new primary piston assembly into the cylinder bore, the master cylinder reservoir to the master cylinder, the reservoir cap and diaphragm to the reservoir, and the master cylinder to the vehicle.

You should remove the master cylinder from the vehicle, the brake fluid level sensor, the reservoir from the master cylinder, and the seals from the master cylinder.
