My first ever attempt at a light restoration

[blaze_the_6]

Little update, all traces of air con have been removed. The pipework was seriously knackered and it would have been a pain in the ass to re assemble so its all going.

Other than that, nothing really interesting to take pictures of. Just disconnecting various wiring which is seriously hurting my head

Got a few questions that are probably stupid to most.

What is this? [attachment=20254]

How do I remove the rest of the master cylinder? Do I need to prise the cover off like a paint tin lid?

And do people that remove the air con block this off in any way: [attachment=20255]

Thanks peeps
