    check your flex rubber hoses
    when old they will swell like a Balloon
    under pressure
    changing will solve many brake problems
    if nothing else, Remember this, will save you much heartache

    Your words are good timing ...yes stupid me .. I've discovered that the problem is a hydraulic thing after all.. The hose maybe it .. but I think there is air trapped in the pipe .. the curved section over the diff centre .. it goes up and over the diff ...

    I'm going to disconnect the pipe at the rear hose and plug the pipe , then play around with pressure bleeding from there. But I know that faulty hoses can behave like a one way valve ... forcing the brakes on permanently = smoke and hot drums

The brake place should have radiused the linings to fit the drums , they used to do this years ago on a machine , when oversize linings were fitted , but apparently it isn't done now.

    Any comments ?

    They should still radius grind i was still doing it 4 years ago, It is a specialist thing though, is the problem fixed? a low percentage of contact can give the feeling of a spongy pedal but most likley the hoses

    [QUOTE=series1buff;1346119]Roger that,

    I used a brake joint in Warragul, I'm not very happy with them . I asked for soft linings as it really helps with old cars ..more braking effect. They sent them away and it took weeks , after all that they stuffed it up anyway .

    Ask for the moulded linings Some just call it roll lining as it comes in rolls of 2m or more "original" its the softest for modern applications the only thing softer is woven which you can still get. prob good for standard series 1

    Always try to get the moulded as the minimum thickness on drums and rotors is less these days i found with harder segment type linings that you will be lucky to get to second oversize any more combined with the lack of asbestos

    at last

    My brake saga has gone on longer than the water pump one on this forum....

    I disconnected the rear brake hose at the pipe side and screwed on a fitting with a short bit of 1/4 pipe , then used the garden sprayer to really pump in the brake fluid. The problem was the long line to the pass. side cylinder .. yep, air trapped in it . After opening the bleed screw , the fluid really spurted out , you need to do this to get rid of all the trapped air in the bump over the diff housing .

    Well it worked and I finally got a nice high pedal . Carefully reconnect the hose and its done . I pushed a stopper/plug into the pipe while it was disconnected from the hose , but the fluid didnt want to run out anyway .

    The problem is 1/4 pipes hold a lot of air
