Hello everyone. It happened again, my Mondeo is standing. Yesterday there was a change of the front brake blocks with me. I then got the blocks and the grease. Spring off. Brake caliper with the 7er Imbus removed, the bracket with the two machine screws cleaned for cleaning also and cleaned with a wire brush. The old brake cheeks removed. First of all scared, because it really needed to be changed, although I only 35tkm of motorway drive dam With a combo tong (I don’t know any nice method) the pistons were pushed back. Before the tank opened for you brake fluid. Something greased, blocks back in. Saddle over. Screwed and spring back on it. Everything so far as in the picture book. It worked great. Brake fluid checked, ok the stand was a bit rough high by pushing back the pistons. But well was explainable. Tested whether pressure is on the brake pedal, check. Pressure set up and a piece of g When driving pressure away. As soon as I rolled 5cm I was able to press the pedal in until impact, however, at the end of the pedal had a very good braking effect, in which he almost blocked always. First thought, air in the line. Front wheels again. Ventilated. Wheels again. Driven. Same problem. Next thought to exclude sources of error. Brake fluid change at front and back complete. All wheels from time to time pumped and ventilated. Wheels again. The same problem still. In the stand it builds up fully pressure. As soon as I drive I have only stop braking effect. New brake fluid, discs front 50 %, blocks front new. Back still drums which are also relatively new. Sorry for the long text. Does anyone still have an idea what it might be about? I was already made to the suggestion that it is the main brake cylinder. That the air has in it. Possible ? I’m open for suggestions. Thanks already
