Brake lines revisited

The brake lines were a job I'd considered to be "done" for a while now but something I read recently made me decide to modify the areas where the copper pipes connects to the flexi hoses. I'd read that, if made from aluminium, the brackets used to support the pipe to flexi joint can fail IVA due to possible work hardening of the aluminium. Even though the aluminium angle I'd used was fairly thick, I'd rather not take a risk on something I could quite easily change at this stage.

So, at the back, the four old brackets were removed and replaced with new mild steel brackets which had given a coat of POR15.

At the front, I was originally going to use the side panels to support the joint on each side, but if aluminium brackets can fail IVA then in theory then so too could fibreglass. Since I'd already drilled holes in the side panel just behind the wishbones (and not wishing to drill more) I made up a bracket just behind the existing holes so that the flexi can pass through the side panels.

The connection now feels very solid. Any flexing of the bodywork will have no effect on the brake lines since they no longer come into contact with each other.
