The Audi 100 Quattro was available as a 4-door sedan or 5-door wagon. During the development of the Audi 100 Quattro, many parts have been built, such as the clutch master cylinder. There is also a reservoir directly above each clutch master cylinder which stores a sufficient amount of brake fluid to prevent air from accessing the cylinder.
Audi 100 Quattro offers great parts to customers. But there will be several problems after the clutch master cylinder has been used for years. Use only the recommended fluid for the clutch master cylinder as any other fluid not recommended for the vehicle may cause damage or faster wear on parts. Signs of a failing Audi 100 Quattro clutch master cylinder include low clutch fluid, soft/spongy clutch pedal, and so on. From the body to the performance parts, a long catalog of advanced Audi 100 Quattro products is given here. There are plenty of inexpensive and quality products online.
