Hi all, '75 Vette. There is a metering valve below the brake master cylinder that meters brake fluid to the different wheels and has an electrical contact for the brake light. On the side of this valve is a small rubber diaphragm about 1/4 in. in diam. There is a pinhole behind this diaphragm where brake fluid is weeping out and past the diaphragm. What is the purpose of the weep-hole and the diaphragm ? The diaphragm popped out and I had a terrible time getting it back in place. Don't know how long it will remain in place now. TIA
