Hi Brett it was the old pads I put back in as they where still good.
Just had the car re-MOT'd today an it was a PASS! Brakes were still off a bit but were within tolerance. I told the guy at the MOT station that he had failed me on was the PSD and he agreed not to test it. I'm satisfied that it isn't a safety issue. I have sprayed some grease on the lines and will replace them and service the PSD in the winter.
The garage owner was pretty cool, he didn't charge me for the re-test despite me taking the car away and he also did a free oil change using oil I supplied. So I'm pretty happy with Carnies Autocentre in Edinburgh
