For 1990-2009 cars only
The master cylinder is designed for a brake system with low drag calipers.
Master Cylinder Identification
Identifying information is stamped into the front surface of the body of the master cylinder.
The Delphi master cylinder has the following information:
| • | The first two digits identify the build code. |
| • | The third digit indicates the year the master cylinder was built (Example: 5 means 1995). |
| • | The last digits indicate the day the master cylinder was built (Example: 271 means the 271st day of the production year). |
Reservoir and Cover
The reservoir and cover used on these models are plastic. The cover snaps onto the top of the reservoir. There is a seal between the cover and reservoir in order to keep out contaminants.
Keep the master cylinder reservoir filled. This ensures adequate reserve fluid and prevents air from entering the hydraulic system. Fluid expansion due to heat absorbed from the brakes and engine makes it important that the reservoir not be overfilled.
