cf685f Posted January 3, 2016 Share Posted January 3, 2016 I looked at a 1970 R Mack. It had no front brakes. Where brakes optional on the front wheels back then?Also excuse the lack of correct terminology, it had an underslung springs. Is that a good setup or should I look for something different. Hoping to pull a trailer with a show truck/tractor on it. Wasn't sure about the brakes, and I want to make sure it was worth looking at.

j hancock Posted January 3, 2016 Share Posted January 3, 2016 Mack had available inverted camel back suspension and it will do ok for your hobby trucks and tractors. No front brakes shouldn't be a deal breaker if the rest of the truck checks out. Quite a few older trucks at shows with no front brakes. Back in the day, single axles trucks had to have brakes front and rear. Front brakes on a tandem were optional. Quote JimIt doesn't cost anything to pay attention.

Superdog Posted January 3, 2016 Share Posted January 3, 2016 You don't have to have steering axle brakes on any tandem axle tractor built before Jan.1.1979,if it were a single axle or a straight truck,you;d have to have them.the underslung ,or inverted Camelback was pretty popular spec for highway tractors in the time frame,was supposed to offer a softer ride than standard Camelback 1 Quote Link to comment https://www.bigmacktrucks.com/topic/43363-1970-r-mack/#findComment-318423 Share on other sites More sharing options...
cf685f Posted January 3, 2016 Author Share Posted January 3, 2016 Ok thanks for the reply's. If things come together I may make an offer. Nice running truck, motors been replaced as it has a 237 with a tip turbine on it, from my notes a 70 should of had a ole 237. My only reservation is that it has significant rust on the drip edge the whole way around the cab. Im not sure how hard that would be to repair.

thomastractorsvc Posted January 3, 2016 Share Posted January 3, 2016 As long as it is not rust out not rusted out (larger than a pin hole) easy fix, wire wheel or sand blast and coat with primer sealer than with automotive seam sealer paint. If it is more than that than maybe some work.If you decided to pass post it here someone may want it. Quote Robert"I reject your reality and substitute my own."
