question Neat brake.

[ace1]

What is the pourpose of the neat brake on a pioneer?:help:

As i understand it the rachet that allows the brake to be gradualy applied if you are on soft ground with one side spinning, which puts more drive to the other side allowing the lorry to drive on.

This was told to me by an old mate, (he likes to wind me up) it does work on a car, with carefull use of the handbrake, but i havent been able to get my pioneer stuck, (yet!).:cool2:

I am sure there is someone out there who can say if this would work.

Alan,

 

Using a handbrake on a driven axle does work as a form of diff lock, so your mate was not wrong, but I think that was not the reason old trucks of that era used Neate type brakes, it was to enable the handbrake to be pulled on tighter than a normal brake lever, could be wrong on that assumption of course :undecided:.

[Richard Farrant]

The neat brake will have no effect on the differential action as it brakes the pinion, in order to slow the diff action the halfshafts have to be braked.

 

The neat brake is there to allow a smooth hill start, this can't be done easily with the ratchet handbrake.

 

On later Explorers the neat brake was substituted with a 'hill holder' lever that can be used to hold the footbrake down for the same reason.

 

It is too late, I was thinking of Neate brakes in Militant Mk1 and others, not Pioneer in particular, time to switch off I think :embarrassed:

 

thank you Bernard.

The Neate handbrake was a standard fitment on most vehiclesof the era, By taking multiple strokes when applying the handbrake, greater slack can be taken up, than by a single pull. In a system that has multiple pivot points and compensators, there is a lot of clearances that need taking up. The fitment has nothing to do with improving cross country performance, since many (or most) road going road vehicles also had this brake.

 

Having watched the old school drive these trucks, there is a tendancy for them to apply the handbrake on downhill descents as the primary form of braking, as it allows you to keep the front brakes cool as an emergency backup, ( I know this doesn't count on the Pioneer unbraked front axle). But the Neate gave a more gradual controlled application.

 

Also braking on the downhill ,by using the handbrake, reduces the risk of front wheel shimmy that can occur on older vehicles when braking is applied to the front axle.

The neat brake on the pioneer acts on the wheels using the same mechanism as the foot brake, not on the pinoin.

It also has a prop shaft brake, but this should only be used when stopped, or an emergency, because you can snap the universal joints.

Richard, I had just deleted that post because I was confusing the Neate brake with the transmission brake on an Explorer, a case for reciprocal deletion if ever I saw one.................:red:

I am having the same problem, by the time i type a reply the last post is out of date.

Oh well, i will just have to type faster.:-D

As I said, Bernard, it is too late for thinking :-D

It's the same in the clubhouse this time of night, everyone talking over each other all the time, and talking rubbish! Bring back the old closing times I say.................

Thanks for all the replys chaps, it was a bit late last night when i started this thread,:yawn: if anyone has used this method to get unstuck please feel free to comment.:cool2:

As Antarmike posted, this is not the designed use for the neat brake, but would it work?:???
