View Full Version : Valve by Power Brake Booster 69Z28X33 Oct 17th, 07, 08:13 PM I ordered a brake line kit from D&R for my 69 Z28. It was a 2-piece power disc line set. The front had 5 pcs and my car has 4 pcs. I do not have the valve by the power brake booster. :confused:Did all 69 Z28s have the valve?

Drum brakes used different parts.

It was that way when I bought it in 78. JohnZ Oct 21st, 07, 06:20 PM What about 4 wheel disc? JL8 cars didn't use the metering valve, and used a different master cylinder. :thumbsup: JohnZ Oct 21st, 07, 06:24 PM My car does not have the original master cyl. or the round metering valve on the left side of the brake booster and I did not have any problems at all with the brakes that I can remember. It was that way when I bought it in 78. You'd probably only notice the difference (not having the metering valve) when driving at low speed in snow. :thumbsup: |
