Trip preparation if travelling on corrugated road

[AustinD4]

Hi Troops, a 2 minute trip preparation tip that can save an upset brake system.
Just returned from a trip up the Canning Stock Route and out through Rudall River Nat Park. Mud, rocks , sand, sharp shale - we had days of it all. The Disco was made for it and travelled beautifully over days of very severe corrugations. During one of my vehicle checks I noted that the rear right brake line had jumped out of its retaining hook and had been scraping over the inside of the tyre. I was lucky that I caught it before it had worn through the break line as most of the wear was into the plastic protection sleeve, but as the wheel was constantly covered and rubbing course wet abrasive sand, we could have been very unhappy campers way out at Lake Disappointment!


So after returning the break line into its retaining hook a very simple cable tie was applied between the hook ends ensuring that the line could not be vibrated out again. The left hand rear line is slightly different, but can also be attached to its keeper with a cable tie.


A 50c fix that is essential when tackling corrugations or constant rough conditions. Ive attached a photo of the RH rear break line and hook with cable tie and placed white paper between the chassis for clear contrast. You can see the damage to the plastic cover and line.


Safe travels

Scary how easily that could have become a major issue. Thanks!

Looks like the park brake cable to me and not the hydraulic brake line

Agree. Looks like EPB line.

Regardless a good bit of advice.

It is the park brake cable. mine did the same thing (RH side) on the CSR last year

[jon3950]

Yes its the EPB cable, had it happen on mine. Stuffed if I know how it managed to escape but I suspect it was knocked out during a service. I had a good look at it at the time. I think its very unlikely to come out in normal operation, rather it needs knocking out perhaps by going over a large or rock or in my case by a hand.

Of course stranger things have happened and definately one to watch for.

Cheers,
Jon

Thanks for your comment guys,
I now understand that the cables are EPB. I wont be travelling without the cables captured with ties again.
PS. Sorry about the spelling -jusrt rushing between work jobs:

Mine was left out when i had some work done on the car. when i realised and tried to put it back in the hook i couldnt get it between the hook and lower suspension arm.

i had to lower the car to access height, jack up the wheel off the lower arm so the car settled a little further trying to re-level, and only then could i squeeze it back into the hook.

There's not a lot of space between the lower arm and the hook - i have no idea how it could come out under most driving conditions.

Vibrations do amazing things!!!

Too true.

My MY10 D4's cables were wearing through the hooks so I fitted and cable-tied slit heater hose to stop movement.

[justinc]

Like Graeme i have seen many almost worn through the hooks too...

A most interesting thread this.In Geraldton for the week and getting the D4 serviced before we head West to Alice Springs along the great central road and this item is now on the service check list

Tombie there are times where you serve up some absolute pearlers. :D

However on this occasion I will not take the bait - I make no further comment! :angel:

[Tombie]

I am most disappointed....

Seems said bait was available for inspection for nearly 4 days so it might be worth replacing... ;)

However I agree that vibrations CAUSED BY CORRUGATIONS do amazing things. After more than 20 years in Arnhem Land nothing surprises.

Mine has worn the hooks too, when (or if) I get my car back from the transmission rebuilders I'll post up a pic

[Disco-tastic]

That would be great shane. I can't get my head around how the rubber/plastic brake line wears through a stainless steel hook...

Very timely thank you. (Writing this from Birdsville). Here's my left side hook after many km's of rough and corrugated roads. You can clearly see the wear pattern. Right side similar.

I can't get my head around how the rubber/plastic brake line wears through a stainless steel hook...Stainless steel is quite soft and its the grit that does the wearing.

easy...

a bit of dust or sand gets trapped between the metal and the rubber, the rubber gives up first and gets the grit trapped in the rubber... the bit of grit held by the rubber now begins to rub on the metal in exactly the way a bit of 1 grit sand paper would rub... add some more grit and how many thousands of bumps with the corrigations or the engine idling away or the suspension flexing up and down and...

thats how rubber lines grind through metal.

[DeanoH]

oops.!!

[Disco-tastic]

Ahh yeah that all makes sense. Thanks for the replies :)
