Brake pipe over rear axle mounting plate.
« on: April 18, 2021, 03:12:24 PM »


In several pictures I noticed that there is a mounting plate with the rear brake pipes fastened to them with p clips.
My 60 LHD pickup doesn't have these. Are they needed?
They look easy enough to fashion ones for my Rover so when I replace the springs I could slide one in.

Any chance some one have a pic or drawing with measurements to use?

Thanks, John

The plates are there to prevent the axle drop straps from rubbing against the pipes.
Not every vehicle still has these straps; some people feel they are not required, and leave the shock absorbers to limit the downward movement of the axle. It's possible that current shock absorbers have internal rubber buffers to cushion the blow when the shock absorber is fully extended, but that isn't guaranteed.

If your vehicle has the straps, or you intend to fit them, then the plates are definately a good idea, to stop the brake pipes being worn through by the straps.

John,
   I know I have at least 1, it's yours for the cost of shipping if you want it. PM me your address if so. You might be able to find some closer on the Guns and Rovers forum.

Brackets in place...





I slipped some rubber tube over the copper brake pipe before flaring the ends.

The pipes are then secured to the brackets with P-clips.

Some strap the longer rear brake pipe to the axle casing with a large/long cable tie for extra security.

Thanks all!   
I fitted axle straps as my Rover didn't have them.
So obviously I will need to make a pair to put on.
I dug out enough mild steel plate that will do and started cutting them to shape.
New springs are on order so when I do the replacement then I will put the plates in.

Btw, the diagram was great!

Hi,

Too my eyes, the plumbing hung onto  Landy's rear axle looks like what my father would describe as an "apprentice draughtsman's job".

All my new chassis projects have had each rear brake connected to each of the chassis main rails, by stainless braided hoses, similar sort of layout as the front brakes ...  all four brakes were individually "hosed" from the chassis rails.

I took the opportunity to fit a hydraulic stop lamp switch to on top of the foot box away from the "muck and the blood and the bullets" under the steering box, by connecting it  into a multi-way connector, with the same connector splitting the left hand and right hand plumbing.

Any time I had to use a ONE IN - ONE OUT connector, I used a 3-way connector instead, with the surplus hole blocked with a bleed nipple, just in case. I never had cause to regret this.

Easier to do, than to describe. And each to his own.

I bought some new plates from Bits 4 Landys. The have two large holes and only one small hole for P clip attachment. Should there be one or two p clips on each side?

Thanks

It really doesn't take long for the straps to wear through copper pipes either, I had it happen on my series III but I fortunately noticed the leak before complete brake failure.

Obviously the plate need to separate the strap from the pipe so on SWB vehicles with the springs under the chassis rails and the straps on the outside of the chassis rails, the part of the bracket that sticks out from the spring goes towards the outside of the vehicle.

On LWB models with the springs outside the chassis rails and the straps running from one side of the chassis rail to the other side, the plates need to face the opposite way around.

Hi, Do the brake pipes attach to the outside or axle side of the plates?

They go on the outside of the plate.  The axle strap goes on the inside, between the plate and the axle.

I believe  having one flex to the centre of the rear axle , is to keep it away from anything that might get wrapped round the wheels when off roading from ripping off the brake pipes , I have seen it happen on the fronts and seems to me to be an eminently good idea  to minimise the risk

Also, the centre of the axle doesn’t move around as much as the outer ends, giving the flexy an easier time.

Even on later ABS vehicles, both hoses to the rear axle go to a union on the diff. I've never damaged a rear hose, but have torn the odd front hose off with quite frightening consequences.

Hi Diffwhine,

So the solution would be to not fit flexible hoses to the front brakes?  :stars

I accept the point you are making, but in that case, I suggest that the current front braking system is unfit for the particular purpose that it was being used for at the time. Visions of a single hose to the front differential, and armour plating around the flexi-hoses. ???
