Brake question

[Classicfordguy]

Finished pulling a stump at a friends house today, afterwards I realized the power brakes stopped working. Is there a way to test weather its the booster or the vacuume pump?

They work the first time you hit them but after that they take a while to build up again.

Any thoughts?

Thanks,

A quick test is to unhook the vacuum line from the booster, vacuumshould hold it to your finger at an idle. Boosters going out will usually make a hissing sound before they quit, leaking input shaft seal.
