Abstract
An accumulator for use in a brake booster having a housing with a piston located in a bore. The piston has a plug attached thereto. The piston moves in response to a predetermined thermal expansion of a fluid in the accumulator. A predetermined movement shears the plug from the piston to prevent damage to the housing by venting the bore to a reservoir.
