Hello - and help! Failed MoT.....

Front brake light switch replaced and working AOK.

Rear suspension serviced but have not yet replaced the bush as I couldn't remove the original bush and ball joint arrangement from the shock eye. I've now found a sectional drawing of the shock and can now see what's going on so will have another attempt...

Thanks to all that have offered advice - it's appreciated and has saved me loads of aggro (and some time too!).
