Capri - Replacing front brake hoses.

This is my first post for some time having been unable to do any maintenance on my cars due to various reasons.
I have not replaced the front brake hoses since owning my Capri XL and was a little concerned with some corrosion on the left front hose. I was able to locate a set of replacement hoses on UK EBay which is a good source for small Ford parts. I try to buy brand replacement parts and I like QH parts and they are often advertised. The cost was a bit more that I thought due to postage and GST (this is something that has to be considered now when buying parts from the UK).
First concern was whether the new hoses were correct. After putting them beside the existing ones, they looked correct so I started to disconnect the RH front hose.
Disconnecting at the disc end is not a problem but the hoses go through to the engine bay. As when doing anything on the auto with an automatic choke, the RH side is a nightmare. The connection with the fixed brake line is just under the end of the battery tray, under the coil and under many other hoses. I loosen the coil so I could get better access. It also took a few sprays of WD40 to undo this connection. (See the centre photo. The connector is just to the side of the battery tray).The LH side has heaps of room and access is not a problem.

I had two big dishes under the car to collect the brake fluid and after the brake fluid had drained, I noticed that the bottom of the master cylinder was covered with gunk! I guess dirt from the old lines. I should have really taken the master cylinder reservoir off and cleaned it but took the short cut by cleaning it with a paper towel and a rag. This soaked up all the rubbish and left the inside quite clean.
Some new Dot 3 fluid was added and I waited a while until I tightened up the bleed nuts. Then I bled both side several times using the one man brake bleeding device. The pedal pressure came up really well.
The only trouble with cleaning the back section of the reservoir meant the fluid in the front section looked very dirty so that is the next job.
I did the same with the rear line. Remember, it has only one bleeding nut on the LHS. After doing the same process, I am left with a brake pedal which is nowhere near good enough so I will need to go through the process of bleeding all the wheels again. A bit of a long drawn out process but at least I have new brake hoses and very clean, new brake fluid. I finally bleed all the lines about 3 times and although it is pretty good, I think it could be a fraction better.
So, now after all of that, I have new front brake hoses.
