I found this forum while searching for how to replace the front brake wear sensor cable on an LR4. It goes up behind the inner fender on the L.F. wheel. Thanks to one of the posts giving the link to "Bodsy's Brake Bible", I was able to to the job. This pdf file is fantastic. Much better than anything I've seen for instance than instructions on the subscription service DIY.Alldata.com. I use AllData.com for Mazda3 repairs, but it is no where near as clear as the information in Bodsy's Brake Bible".
