Continuing the brake system installation that has turned out to be time consuming and a little frustrating at times as the brake pipes are so rigid that they are difficult to handle.
The tunnel is positioned to see how the park brake unit would sit on the airframe.
There is a service hatch on the tunnel moulding that allows you top access the pipework and park brake actuator when required.
All 1/4″ NPT brake fittings require Loctite 577 to seal the threads before fitting.
The complete unit ready for installation.
6mm holes are drilled for a couple of M4 rivnuts that will secure the park brake actuator.
The unit is sandwiched between a couple of pieces of anti-vibration rubber and an aluminium top plate and the secured with a couple of M4 x 40mm cheese head screws.
The installation so far. Such a straight forward piece of work but it’s taken ages to get this far.
Now the park brake unit is in place the pipework to the disc brakes needs to be run. The pipe is very rigid but it becomes pliable with some heat which allows it be moulded more easily.
The rigid pipe needs to be protected with a cover so I’ve used some cable spiral wrap which seems to work well.
