Redoing your entire brake system? Don't forget to replace these small parts that play an important supporting role with the master cylinder. The complete master cylinder reservoir comes complete with the cap and seal, so you don't need to order one along with your new reservoir. New grommets for the master cylinder feed lines should be used if you find that your older ones are cracked or brittle. Manufacturer - OEM Porsche

Brake Booster
The brake booster is a particularly expensive piece to replace. There is only one manufacturer of these, and they price them in the stratosphere. The good news is that these don't usually need to be replaced. Used on the power brake cars, they accept a vacuum hose from the engine manifold, and use that vacuum pressure to assist in the movement of the master cylinder. Be very careful when reattaching the brake booster to the master cylinder. Using too much torque can damage the delicate booster housing, and render it useless.
