front hand brake issues

Hey there
I have ben trying to fit a front hand brake and drums on my early R4 from 1964 ( the previous owner had it swaped to disc brakes ) and I have some troubles doing that so I thought you could help me.

I've got some questions

1st - I visited franzose.de and noticed that there are two lenghts of cables for the front hand brake. Ones are 1055/1495 and the orhers are 1035/ 1479

As my car was modified by the previous owner a lot , I have no idea from what year the parts I got to restore the brakes are. How is it possible to determine which cables I need ?

2nd Did the early models have limiting valve at rear brakes to reduce braking force depending on the car load ?

3rd question is about mounting the hand brake mechanism lever under the hood. I noticed that there are two holes with thread in the chasis that fit perfectly but the mechanism should be bolted with four screws so half of the mechanism is hanging in the air and I don't know if there should be some support mounted under it to bolt it to it? A picture to help you understand what I meant :)

Hi Chudson Can only help you with point 3

Point 3: Although the mechanism has 4 holes, only 2 of them get screwed in and you're correct, the other side hangs in mid air.
Both my cars are like that.
It's probably got something to do with left hand and right hand drive cars

I'm sure that someone else can help with your other queries
 
In my Heynes manual, it says that ALL models are fitted with the brake pressure limiting valve.
It also says that "several different types have been fitted to various models"
so good luck with that.
I'm sure that your car must have one already fitted.
 
Actually my car doesn't have the valve but it might have been removed. Fortunately I have one from another R4 bought for parts. I have found repair kit only for 13,7mm vale hope it will fit mine.

I found A company that produces automotive cables and they will fabricate me the handbrake lines but i need to be sure of the correct lenght. I'm guessing i have the later model.
 
Although Franzose lists only two cables for pre-66 R4s (one left, one right), it is not necessary that they will fit your car, I guess it has been "tinkered" by various hands in the past.

The best would be to assemble the whole brake and handbrake lever mechanism, then have the cables made by dimensions, the firm who make them should ask you which dimensions they need.
 
For me one you posted from franzose.de looks like it does refer to the load of the car.

This one doesn't seem to be load dependent: http://www.franzose.de/en/Renault/R4/Hauptbremszylinder/ANR84095/


I found the later type valve with 4 hydraulic connectors on it in some boxes I had bought with the car. It has two springs a lever and a half ( cut ) of a backplate. Does anybody have pictures where it should be mounted ?
