I decided to get the 66 out today, but no brakes. I have had a leak but not one as severe as it now is. Can't locate by looking underneath so took to my mechanic. He is looking at lines, wheel cylinders, and power booster, master cylinder. As it turns out, NAPA can get or has all parts. They have in stock the front cyl and the master cylinder. My question, they can get master cylinder/power booster combo. If my master is OK would you replace anyway with a fresh rebuilt combo?
