|Sometimes new vents have to been used. For bleeding a System has been
used : EeziBleed-System for instace M.O.V. GmbH. http://www.colortune500.de/ (45 Euro).
With this system the pumping operation of the brake pedal will not longer exist. The brake fluid will be inserted into a reservoir with two hoses. One will be connected to the Main brake cylinder, the other one to the compressed air connection (max. 1,2 bar). You can also use a bycicle pump.

|I have used a stainless steel sheet metal for the braket of the brake hoses, it is 2mm thick. The slot sideways to the path throughs allow the de-installation of the brake pipes, for instance if you want to change the brake disks.

Brake disks have to be removed every second year; otherwise they will corrode and you will not be able to replace them|
