UK MOT's
Darren:
Thanks Don really appreciate the help. The hose is new and both the callipers have been stripped down fully twice. Everything is free as it should be.
I wonder if I took the fuse out for the ABS if the problem would still be there when on the machine? Is there a fuse, there must be?

Were both hoses brand new?
Here is what happens when you put the brakes on. You have to become the brake fluid and try to make your way to the wheel cylinder so you can do your job and stop the wheel. This is how I try and think it through.
When you step on the prake pedal you push brake fluid out of the master cylinder. Some goes to the front and some to the rear. What goes to the front goes into a "T" so that it can split up for the left and right front wheel. It now goes to each wheel where it has to pass through the flex hose then into the wheel cylinder or caliper.
I know it would be a pain in the butt to do but if you were to disconect the brake caliper and put a pressure guage on the end of the flexible brake line and put an equal pressure on the brake pedal while you tested both right and left sides. This would at least eliminate your hoses and brake lines as being suspect.
If you take the vehicle for a short drive in the country without using the brakes very much. Stop and pullover and put your hand on each wheel. Is one warmer than the rest? If it is that may be where the problem is.
I had a car one time that had that problem. Get to work after a 15 minute drive in the country and one wheel was hot. thought is was a bearing. Nope. It was the flex hose holding slight pressure on the brake.
That all I can think of for now.

New hose on the low side only...
Circuit is a tad more complicated,
master cylinder-abs splitter-wheels
Great thinking about the disk temps, I'll have a quick drive and test that tomorrow.
Now that I have a MOT I can drive it. Driving without one in the uk is now a serious offence and as the MOT results are now computerised you get caught pretty quickly from number plate recognition devices fitted in police cars.

"New hose on the low side only..." --Is this the side that has the low braking pressure?

Darren:
Yes, it was changed but made no difference to the results.
