Hello,
I´m from germany and not sure if I should post my question here (Forum rules: ... no bad language ...) -> sorry for my bad english :wink: !
I have bought me a P6 from 1972. It´s a 3500 automatic. LHD. Originaly from sweden. And it entertains me with some strange problems with the brakes. The servo-cylinder has got new rubbers. It creates a quite good vacuum (If the engine is turned off, the vacuum in the servo is enough for 3-4 times pressing the brake-pedal. You can hear the pffft.) So the vakuum and the valve at the master-cylinders also seems to work right.
But it feels like no servo-support at all. I tried some things:
1. If I disconnect the hose between the servo-chamber and the air-valve at the master the servo works: the rear brakes are nearly blocked. But the front-wheels can still be turned easily by hand! No braking here at all! (This should not be possible, because the servo presses at first an the cylinder of the front-brake-circuit and this cylinder (or the brake-fluid in between) presses then on the separat cylinder of the rear brakes!) If I then press the pedal, there is braking-power also on the front-wheels and stays as long as the hose is disconnected.
2. If the hose between the inlet-manifold and the servo is disconnected (no vacuum) the brakes front and rear work. But no servo-support.
3. There is still some air in the front-brakes - tried it with eezibleed. Will try it again the traditional way. -> But a little air should in my opinion also transport so little braking-power, that the front-brakes should work a little !? But they don´t work at all in this #1-constellation. In the #2-constellation they work so good that the front-wheels can be blocked on grabbel. Pressing the brake-pedal the first time it feels very soft. The second time it feels "normal". Staying on the pedal it holds the pressure and doesn´t get soft.
-> Does anyone have an idea what the reason could be? :?
-> I`m not really sure, if the servo-cylinder is the right one for my car. Looks like it could have been changed by one of the pre-owners. The Numer on it: "Lockheed 3231 8226"
Where can I get parts for the Dual-Line-System? I´d like to try an used servo-cylinder and maybe also master-cylinder.
Is it difficult to transform it to the Single-Line-System? :cry:
Thanks a lot!
