New premium reproduction tear drop power disc brake master cylinder for the Mercury Cougar or Ford Mustang equipped with factory power disc brakes in front and drums in back. The difference with this premium version, is the "tear drop" casting, and the fact that it comes with the premium master cylinder cap. This unit has a 1" bore and includes a new cap and diaphragm as shown. Unlike many others you will find, this unit does not need brass line adapters to fit your factory lines, they are correctly sized, will not interfere with your shock tower and ready to bolt on. Note that the 1967 - 1969 Midland booster (banded body) requires a spacer between booster and master and the 1969-1973 cars equipped with Bendix booster (crimped together body) does not require a spacer between master and booster.
Replaces Ford part # C8ZZ-2140-A.
*NOTE* This is the service replacement for the 1967 Power Disc Brake (Ford part # C7ZZ-2140-F) and the 1972 Power Disc Brake before 2/28/72 (Ford part # D2ZZ-2140-A).
Do not attempt to use a 1970 booster on a 1967-69 Cougar as failure will occur within minutes!
Never bleed your brakes on a power brake car with the car running. The pedal will over extend the rod into the booster and break internal parts. This is not covered under warranty.
