This option REQUIRES sending your core in advance.
Here are the advantages of pre-sending your core:
We can core match your booster. Boosters that are rebuilt using a superior quality core are always reserved for core matching. If your core is average or below average, you may be able to pay to upgrade to a rebuilt booster that started the rebuild process as a superior quality core.
You can find out the quality of your core before paying a core charge and avoid unnecessary core charges. Discounted core charges may apply for below average cores if sent in advance.
Quality rebuild done by the country's premier classic car booster re-builder! Note that the input shaft tips down for 1969 (pictured left) and goes straight back for 1970 (pictured right), using the wrong booster on the wrong year or pedal will ruin your booster. This is a one year only booster and will not work on your 1967 - 1969. If you have an unusually clean booster core that has minimal or no pitting on the case and it is important that you receive like quality, we suggest you send your core in advance. By doing so we can "core match" and if we do not have one in stock as clean as what came off your car we can rebuild your unit and send it back within about 2 weeks.
Helpful Tip: These boosters are set with the rod at about .950 (with 20" of vacuum) to make sure it does not pre-load the master cylinder. If the depth is .980 (as the shop manual calls out) and one sets the push rod at that when the engine starts, it could move forward a bit and pre-load the master causing the brakes to drag.
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.
