OK, so second test drive didn't go so well. Lulled into a false sense of security from first go. Brakes started to bind after short distance. Eventually locking on. Managed to get back to the workshop. But the clutch didn't like me much for it. It got so stressed it took up smoking. Hopefully the worst I've done is taken a few thousand miles of it's life. I don't fancy changing the clutch just yet. But the next trip out will be the tester. So back to the brakes. The brake lights were on & all four wheels locking. So it tells me something hydraulic is sticking. I first thought about the rear bias valve as it's the only part that could be considered second hand. But my reasoning says if it's locked on I will only loose use of rear brakes, not the whole system. I thought about the master cylinder as I did do some minor modifications to it & it's been on the car about a year in all. Might come back to that. The main culprit in my reasoning was the servo. It was new old stock. looked good, but to be fair I don't know how long it was on the shelf. A little internet reading implied it could be the cause. Basically fluid seeps past the seals & locks it in position. After 24 hours the brakes had unlocked. Starting the engine & testing caused them to start binding again. So another servo is on it's way to me as we speak from MGB hive. It's quicker than a rebuild. The only servo failure I have heard of before either provides no assistance or starts to burn brake fluid through the intake manifold. New one on me. Also the rear wheels have settled & started rubbing the arches. I came to the conclusion I wasn't happy with the position of them. Too far forward. The position was a compromise from the old group 6 arch fixings. So I've decided to move the arches back. This sadly leaves 2 holes & M5 fixings in the panel just infront of the arch in it's new position. Not a good look for a new build. So I am trying to think of a cunning plan to use them for some feature that looks legit. Some cars have a protective panel at the front of rear arches to protect from stone chips. I might butcher some standard plastic arches to create this. But I'm open to ideas....answers on a postcard please.
