kscarbel2 Posted March 18, 2020 Author Share Posted March 18, 2020 Nobody hated Rockwell's "Stopmaster" wedge-type brakes back in the 1970's and 1980's more than me. Nobody. However, the modern European wedge brakes actually work well. Solid performance, lower cost and lighter weight wheel ends.

Lmackattack Posted March 18, 2020 Share Posted March 18, 2020 Its odd to me that Mack is offering these heavy rear ends yet removed themselves from the big HP market. in most cases the heavier the GVWR of the truck the more HP is speced under the hood. it like saying Mack has heavy rears to carry the load but we fall short in the HP to move it ( when compared to other MFG) not the idea way imo 1 Quote Link to comment https://www.bigmacktrucks.com/topic/61515-mack-85000-pound-tandem-axles-available/page/2/#findComment-445950 Share on other sites More sharing options...

Probably offer the heavy rears to get a customer in the door. Then when they find out they can’t spec what they want under the hood the sly salesman pitches them a Volvo.

Never been into them myself so can't answer as to why they work but they will put you into the glass if panic applied and not ready for it. Never have had a wheel end open so can't vouch for anything about them at all. I remember well when they were common, but I've never worked on a set myself.

Rob Posted March 19, 2020 Share Posted March 19, 2020 Thanks Kevin for posting up the Midliner stuff. Those trucks will always hold a special place in me as they rendered such good service. Not once did any have to be retrieved away from the shop. Only one that was marginal was a water pump loss. It was summer and the driver stopped every 50 miles or so on Rt. 54 through Missouri to refill with water and made it all the way home without overheating. I gave him an extra "Franklin" for looking after my equipment like that. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Bullheaded Posted March 19, 2020 Share Posted March 19, 2020 There are three Midliners in the town near me. One is a boom truck and two are tractors. And they are still going strong. Actually 4.....there is a box van with a paper shredder in it.

I sold two of mine to a auto body repair outfit in Missouri, and one to a private owner to haul his Packard limousine car. I heard my black one burnt up in a building fire a couple years after being sold. Sure missed that one as most around here knew me by that truck as rollbacks weren't all that popular in those days; but were gaining. I'd be willing to purchase another CS-300P if could be found without rust, which will be hard to do.

Quickfarms Posted March 19, 2020 Share Posted March 19, 2020 I have planetary’s on the Marmon Herrington front axle on my navy truck. They are just fine at 58 miles per hour, no real heat build up, just warm to the touch. My only issue is the seals Marmon Herrington uses are wet and the planetary only holds about a quart so they are checked regularly 1 Quote Link to comment https://www.bigmacktrucks.com/topic/61515-mack-85000-pound-tandem-axles-available/page/2/#findComment-446022 Share on other sites More sharing options...

I'd like to see that all put back together.The truck was military surplus with a lot of deferred maintenance This is the first version of the truck That picture was taken during a rebuild to correct some things I did not like from the restoration. The main change was to install a tilt front end and new camper It’s still a work in progress but now my wife will go with me to some of the shows 4 Quote Link to comment https://www.bigmacktrucks.com/topic/61515-mack-85000-pound-tandem-axles-available/page/2/#findComment-446097 Share on other sites More sharing options...
