Is this brake booster good?
It came from my 1990 parts car and is a factory PBR unit. I am not sure how hey should react to vacuum. Here are the results ....
Hooked to my running engine pushrod moves freely.
after motor is shut off pushrod moves freely about 2-3 times then gets really hard to push.
a vacuum pump hooked to it and 23 inches of vacuum applied it will hold that vacuum for a easy 20 minutes without a loss.
Basically a buyer is interested in it and wanted to know if it in fact is a good booster.
