I'm glad you are happy with your DMUK work Stephen, Are you on commission?
Seriously though, its certainly sounds as though your brakes needed
attention.
Out of all the DeLorean's I have owned, if everything is set up and working
properly I have always found them to be quite adequate for normal driving. I
remember particularly driving , what is now Darren Cunningham car. The
brakes were absolutely spot on, Quick stopping in straight line, even the
hand brake would lock up both back wheels at speed. I think it's often down
the little mileage many of these cars do, things start to sick, rust up etc
and hey presto the brakes gradually get worse.
