gearhead204 Posted August 26, 2014 Share Posted August 26, 2014 I believe you can get parts from Rockwell . if it has bolt on spiders I would change it over to cam brakes. but that me! 2 Quote Link to comment https://www.bigmacktrucks.com/topic/36842-r-models-with-wedge-brakes/#findComment-257450 Share on other sites More sharing options...
Bigdogtrucker Posted August 26, 2014 Author Share Posted August 26, 2014 Just found out the truck was a single axle when new,clipped in the rear I guess.Have no idea if it was a Mack clip???

bobgil Posted August 28, 2014 Share Posted August 28, 2014 I have started replacing the wedge brakes on my 1965 C model. I looked and the parts were too costly to repair so I looked and found the parts to replace them.It is not cheap to buy the parts new to do the change over but they are not hard to find used and not costly as new.You will have to completely replace every thing on the end of the axle from the spider that bolts to the axle to the drum along the all the air chambers and hoses.I found a company that had a huge scrap yard of older Mack's and the parts I needed were the parts that they did not need and are we're too worn that they bought new and I was able to get them for cores.Wish had the job finished on my truck Quote Bob Gil If it an't a Mack could it really be a truck???
