Got a point there.

Give it time, give it time lol.

You need to take the caliper off and disc undo the back blate and move it round a bit to give better access then give head of that set screw a bloody good headache before you try again its a word of pain if you shear it off, give it some heat if you can aswell did that on my first L322 and this...

Somebodys got to !

But what if its a Lady type gentleman, would it still cool the lady type gentlemans area the same ?

TV module on mine did it.

Fit the biggest battery you can find they dont like small batteries.

If you look on the fullfatrr forum (yes sorry about that) near the top for "wiki" you can download the workshop manual from a link on there. Sorry to hear about your friend.

At least my back plate wasn't that bad to need 6mm !

One dodge is to use 4mm set screws nylock nuts and washers to replace the retaining pins (and yes it's what I did having tried other options, it works ok)

All most certainly a vacuum leak and it's not like you hear the hiss like an air leak.

First port of call would be battery I think.

Well its an extra 6 volts but still think would be better on the mains !
