Hi all First of all I have finally got my 1964 1800S on the road after a memorable 3 year resto. I had never driven it as it was a bit of a barn find and was last used in 1992. Having sailed through the MOT test I have now covered around 300 miles of what I like to think of as "extended road testing". I would like to thank all of the forum members for your help and support during the rebuild. However, as we all know - it doesn't stop there. From day one i noticed that the brake pedal travel was a bit unusual although the brakes worked ok. I even checked with the MOT tester and he said they were good. My problem is that there is a lot of pedal travel (about 2") before anything happens and then the braking force is a bit too fierce all of a sudden. Thats what happens most of the time however on increasingly more frequent occasions the brakes sieze slightly - could be just r/h rear - and when this happens pedal travel is reduced to almost zero although the brakes still appear to work well. I have new brake lines and hoses Reconditioned Calipers Rebuilt the rear drums and servo myself using seal kits I didnt touch the master cylinder as it felt ok at the time - could this be the cause? Can it hold hydraulic pressure internally causing the brakes to bind?

Suspect servo or vaccum lines. Also possible that the calipers are sticky, but if the travel changes...look at the servo. I had an 1800S for many happy years of batchelorhood !

Thing thats confusing me is that servo assistance seems to be there in both cases (loose/tight pedal) also only MOT'd three days ago force good.

Thanks Ron I will have a pipe made up that goes directly from the master cylinder to the 4 way union - I assume this is the way to go
