Brake Booster and Related Components  |
| 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. |
