My 1998 freelander XEi has discs front; drums back. I find the braking not as good as I would like. Having enquired at my garage I was told the brakes were satisfactory and passed the mot. Yet it did not stop in an emergency and I hit a dog I see other members advise against replacing the drums with discs but suggest upgrading the front discs. Can someone please advise what I have to get/replace as I do not want a recurrence. Many thanks. Teresa.
