EH Brakes on FC stock front and rear ends

[CraigA]

Is it possible to fit EH drum brakes to the standard front and rear of an FC?

I'm going to start using my FC again and after sitting for an extended period the brakes are rotted AGAIN.  :-\

This time I'd like to upgrade to EH brakes, mainly because of the better design of the wheel cylinders against moisture getting into the system, but with the bouns of increased brake shoe area.

Has anyone done this, and if so what bits do I need?

Thanks,

Craig.

Hey Craig im almost positive that it can be done to the front end and could possibly be done on the rear end talk to the old man he has done this conversion before and will be able to tell you whats needed

Cheers Ben

Thanks Ben.

I'll drop in to the next meeting and have a word to him.

Hope to see you there as well. :)

If you are to upgrade the FC brakes to EH keeping using your existing FC cross member there are several problems
a) the front end control arms are only interchangeable at the upper inner bearing and lower outer bearing, so you really need an EH front end wheel to wheel to get the upper control arms, as well as the axle, brakes, kingpins and steering arm.
b) brake hoses will need to be renewed with special ends to match new wheel cylinder and existing FC steel fitting.
c) at the back just change the whole axle, renew brake hose as for front, and weld on FC bump rubber brackets.
Brakes are certainly better

Thanks for your response Geoff.

Are there any other options so I can utilise later model wheel cylinders, specificaly those that have a rubber sealed end? Torana brakes maybe?

My hope was that the rear axle to backing plate holes would line up and allow easy fitment and at the front it would be the same deal - bolt up the EH backing plates and change the hose fittings. Not that easy hey  :-\

Has anyone tried the above method and just bolted up later backing plates?? If you did try would it be possible to modify later backing plates to fit?

If its too much hassle then I'll just have the current ones stainless sleeved.

70 XU1, have sent you a PM re your initial question.

i've bolted EJ brakes which i asume are the same as EH onto EK stubs which i assume are the same as FC, bolted the backing plate straight to the stub only drama i had was the steering arm which i fixed with a grinder but if you have the EJ/EH steering arm that should solve that problem

[DN2168]

I am considering the same mod for my Grey & White car. My question is, If you were to bolt a complete EH front end under an FC will that solve the problems or open up a whole new world of hurt?

Thanks,

No it works fine - once in a moment of inspiration I decided that I would put an EH front end in an FC with  a red motor and just make new engine mount plates. The jury is still out on whether I saved any time or effort. :P ::)

Hi Craig  you can use FC front end just got to redrill backing plates, you will have to use EJ, EH, HD or HR rear end. If you use HD or HR rear you won,t have to move the rear flexible brake hose connection on diff housing. I,m going to the meeting tonight so I will see you then.      Al

[Al]

Another way you could go which I have done a few times is use a late HD or HR drum front end, change engine mounts and outrigger. You still have a standard looking drum brake system with ball joints. Gives a better ride and better steering. Ball joints last longer and are cheaper to replace than king pins.

I am doing the FE and after talking to a old brake bloke hes telling me just use all existing brakes with S/S sleeves in them and only use silicon brake fluid found the brake fluid it was $139 dollars for a litre :-[

Apparently it will not absorb moisture and they do not stick after sitting for a while.

He had a bug sit for ten years rolled it out and reckons they were not sticky at all....

Gotta be worth a try...

[fc058ute]

you  can fit eh stub axles and brakes complete by swapping over the top and bottom control arm outer pivot bushs and bolts  as eh ones are bigger

[mcl1959]

Silicone brake fluid is good as it doesn't gum up like normal brake fluid, the only downfall apart from the price is that it will find a way to leak where normal fluid wont. The entire brake system must be perfectly clean and in absolutely pristine condition before you put the silicone fluid in. You cannot drain old fluid and then put silicone in, all rubbers must be cleaned or preferably renewed including hoses.

thanks for that.
I was told that since i am having them sleeved and recod i could run it and should never have problems.

But it got me thinking the pistons are on the other side of the seals wont they still grow crap on them and gum up or do i put a bit of grease on the pistons.

I always put a bit of rubber grease on the pistons to keep them sliding freely

Hi guys,

I have found an EH front end diff for the car. When changing front ends can I use the old FC outrigger as the front end has had its out rigger removed. I  realise it's not a quantum leap in braking performance, but the HR discs are going on the other Taxi project.

Dean.

[mcl1959]

The FC outrigger does not fit - that's why you use the FB to EH outrigger on a HR front end and not an FE FC one. The FC cross member is deeper than the later ones.

Ken

[DN2168]

Thanks Ken,

I had a feeling that may have been the case.

Dean.

[DN2168]

Hi Ken,

Would I use an FC or EH mounting rubber kit? The guy I bought the front end off gave me one with an out rigger as well.

Thanks,
