Clutch Remote Bleed

There are many advantages to the GD's spaceframe backbone chassis and separate body. One of the disadvantages is that the clutch slave cylinder bleed nipple ends up being pretty inaccessible - the underslung exhaust system doesn't help either! It is therefore necessary to install a remote bleed for the clutch slave to avoid having to take the body off to bleed the clutch.

After pondering this problem for a while I came up with what I think is a reasonable solution. As appears usual the first step was to fabricate a bracket out of an piece of steel angle:After painting the bracket was located on the lower nearside gearbox to bellhousing bolt - behind the clutch slave bracket:The other bits need are some -3 braided tfe hose, a -3 banjo fitting with 3/8 UNF banjo bolt and a -3 bulkhead fitting with integral bleed screw:A short length of hose was made up with these fittings and the banjo end was fitted in place of the bleed screw on top of the slave cylinder and the hose run behind the slave bracket:The bulkhead fitting was fitted through the bracket and bolted up. The bleed screw can now be accessed from under the car and also the bolts on the bulkhead fitting are easily accessible meaning the fitting can be held with a spanner if the the bleed screw is a bit stubborn to undo.Although it appears exposed, the bleed screw is above the bottom of the bellhousing and above the level of the exhausts so it shouldn't come to any harm.
