Looks like my car has come close to failing mot with a advisory on the front and rear brake pipes being corroded so my question is has anyone replaced their brake lines and how easy was it to do I have done some work on the car before but this looks quite involved some people have said that the petrol tank has to be dropped any help would be appreciated

Had my rear ones done a couple of months back, left it with the garage to do, they didn't drop the fuel tank, although was a pig of a job, althought they tend to say that about most things !Cost roungly £300 all in.
