Also, whilst I've got everyone's attention.

I also need to adjust the handbrake. I've read this can be done by whipping out the rubber bung, jack rear diff up, turn bung to 6 o clock, and lever the adjustment cog inside.

My question is, which way? Does the cog need to go up to get tighter (so i'd be levering the screwdriver down), or does the cog go down (levering the screw driver up)?
