What steve said ^^
I understand a little of electronics mate - If you break the circuit to the battery ie - taking the earth away then how will pressing the brake pedal do anything? If the circuit isn't complete how can a current be drawn? The capacitors wouldn't take long to stop holding charge considering it isn't really that high a voltage that runs in the car yeh?
If the battery is disconnected there is no circuit - so I don't see how pumping the footbrake(making the tail lights work) would make a diff... just a few seconds is all..
Don't know how long the mechanical diffs will last but at least if they wear you can still use them - a locked diff will break and thats it - you can't drive it till its fixed...
Yeh I dunno about the environment side of things.. my car has gutted its own cat and now the gas stinks... plus it runs absurdly rich so yeh: DIE MOTHERNATURE..
my car is fast becoming a track car.. but still used for daily driving..
You can see the CAS on your front gear cover - looking at engine from the front - its the silver bit on the right hand side - prolly has RB25 pressed into the cover next to it in your case..
What about this rotting fuel line bizzo I have been hearing about?
How hard is it to add in a couple of degrees on the CAS? just loosen bits off then swivel a tiny bit, then tighten? (with exact measuring taking place of course)
