417mack Posted September 24, 2008 Share Posted September 24, 2008 Need help with 63 b61st. I would like to replace the wedge brakes with Scam style what parts must be swapped. Looks like mounting the new brake chambers will be tricky. Any advice will be much appricated. Quote Link to comment Share on other sites More sharing options...
vanscottbuilders Posted September 24, 2008 Share Posted September 24, 2008 Depending on the location of your wedge type activators and cans, you will probably have to remove and relocate the brake can mounts.It's not too bad of a job, and you can get several lengths of brake operating cams. I would try to get the cans as far from the wheels as I practically could, so you could mount large brake cans, especially on the rear axles, where you might want maxi brake activators too. Check carefully for adequate room. Obviously you will be changing shoes and backing plates. It's a good time to look at wheel bearings, and to change seals and felts also.If it is a possibility - It might be simpler to find used axles with the S cam brakes already on, and just put seals and felts in and linings, if necessary.Good Luck, whatever you decide.Paul Van Scott Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted September 25, 2008 Share Posted September 25, 2008 And drums and some times wedge brakes did not use a relay on the rear. Quote glenn akers Link to comment Share on other sites More sharing options...
wmolddog60 Posted February 10, 2009 Share Posted February 10, 2009 I don't think you can change wedge to s cams unless you change the bolt on spider for brake skoesMeaning you have to pull hub & drums.I might be wrong but I worked on lot of truckswith wedge brakes,different brake shoes Etc WMOLDDOG60 Quote Link to comment Share on other sites More sharing options...
