i have a 2003 active saloon 1.8

there are a few niggles i want to know if anyone has come across and if there are any fixes

1. creaking bootlid when driving, at 1st I thought it was the rear suspension, after a full strip down and rebuild i found its the bootlid ive greased every movable part but short of removing i cant find the cause

2. ive replaced the rear pads and everything is connected up as it was before but my hand brake (pretty sure its self adjusting) is no more and i cant find an adjuster

3. more me been a tube but when replacing the rear pads ive sat the locking nut adapter down somewhere very safe, can replacements be sourced through vauxhall or is it a removal job as i dont want to damage my facelift SRI Alloys

all comments gratefully recieved and feel free to rip the **** for being a tube
