Can anyone help me with finding replacement seals for the parking brake
unit on my tri-gear. I was doing an overhaul this weekend and found some
of the seals were badly degraded, so as I had the unit in pieces it
seemed sensible to replace them all. Also is there a "best way" to
refill the system with fluid?
I thought the best way was to force brake fluid up through one of the
callipers under pressure, thereby pushing the air to the top of the
system. This theory falls down however when you notice that there is a
hole between the cylinders in the nice shiny piston unit that I thought
kept the two brakes on separate systems. So if you fill from one
calliper then you will simply force the air down the other as well as up
into the master cylinder in the engine bay and it will not be possible
to completely purge all the air or am I thinking about this wrongly?
Many Thanks
Alan
