Welcome to BMT. It would be interesting to know how a truck from Poughkeepsie NY ended up in Luxemburg??????? There are some Mack collectors near you in Holland, who have an occasional show. Contact Vlad (from Russia) by PM or email thru here as he has their contact information.

Thank you for the info . I found a grill in Germany on ebay and some sheetmetal parts for a R -Series truck . The guy who had the R-Series parts had a adrress in Holland , Willi Gaffert , I called him and he sell me a cabin with doors and some small parts . He has an N-model lug truck , find it on youtube .  I found an other R Mack in France with a endt675 engine that i bought for the engine . There are some other b- Macks in France but very rusty and expensive . I have a R-600 dump truck too with an end 673 engine , bought it from the first owner , will post some pics later . Wanted the front brakes , never saw a truck without front brakes . I can not registrate a truck without front brakes in Europe .  The guy who i bought the b61 told me that had some freinds in NY . Had some other trucks Chevys and a Firetruck wiht 2 stroke diesel all from NY . Sorry for my writing , i'mnot used to writing in English .

I think it was about the late 1960's to 1970(??) when the US changed the ruling from 2 axles to all axles. Even the 2 axle trucks had a limiter for pressure on the steering axle. This was to prevent "lock up" on snowy / icy roads.

yup, the last truck i drove with a front brake shut off switch was a 79 White 9000.

only in 79 it was called a wet road/dry road switch. and it was air controlled. 

use dry road( all brakes working)  or "wet road" for no front brakes for wet road conditions.

The wet/dry road didn't "kill" the front brakes, it reduced the pressure provided to the front by a percent of brake pressure in the system. I don't remember the exact percent, but my '73 and '69 had the manual valve on the dash and a "ratio" valve before the front brakes.

Modern trucks have the same thing but is automatic will provide full pressure if the brake pressure rises above a set pressure (60 psi?) and on lighter braking reduces brake pressure to the steer.

That is different from when no steer axle brakes, where brakes were not fitted on the hub.

Driving a bobtail tractor with no front brakes on the axle on slick roads is a real pucker factor experience. 

Over the years different things were tried to address the front brake issue. Before the dry/slick manual controlled valve, smaller chambers on the steer (today type 20 is the most common) but that limited braking on dry roads. No front brakes,  Larger chambers and either driver selected or automatic limiting pressure were tried. 

Today automatic reducing valve and large chambers are what is used to meet braking stopping distance requirements, where standards dictate stopping distance loaded and loaded with 1/2 the system inop. Front brakes that can deliver maximum braking force on the steer are the only way to meet these requirements.
