Hello, I own a '58 Buick Century with power brakes (Delco). I had problems with missing power brakes all the time. I used silicone brake fluid.
In the garage the whole brake system was overhauled and changed to normal brake fluid. New hoses, new brake cylinders. The master brake cylinder and the brake booster were overhauled with new gasket sets. Now it brakes much better, but it loses the brake power support from time to time. The booster tank was checked with pressure and smoke for leakage. Nothing to find.
After 2 times braking or when I drive with lightly applied brakes the support is gone and I have to brake "normally".
The windshield wiper hangs on the vacuum line. There seems to be something wrong, because when the engine is running it "bubbles" in the water glass. Can this be the Problem? But According to the manual there must be a check valve somewhere. Where exactly? Is it the T-piece on Picture 2888?Does anybody else have an idea for troubleshooting? Modifications are not an option because of originality.
Regards Andre
