Marko,

I think you need to add the fact that there are a pair of extra callipers needed for this type of handbraking. I have this system in my Abarth.

For some it may be obvious, but for others it isn't. So you are now using an integrated system where the foot brake system runs via the handbrake. It's lighter, but i don't know if it will work as good as a hand brake system in itself.
It will take some time before i have my car finished and yours will run sooner, i guess. So let's see of your system works okay.

Inline cylinder is the most common hydraulic handbrake. Its used practicly in all rallycars, except early 131 Abarth. Only problem in inline system might be if you would want to handbrake same time your braking by foot. There is a pressure in the line you would like to push more pressure, handle will propablybe stone hard. But, I drew almost ten years with 131 which had inline handbrake. I didnt have any problems. When I liked to turn the car in to corner with handbrake, I didnt have brakes on to help the car turn.

Using handbrake in cornering slows the car down. To push a 131 through a corner you need to brake hard with foot, turn the steering one way and quickly the other way. Put the pedal down and the rear end does the rest. That's the way to do so with a rear wheel driven car.
It's just that a handbrake is needed for MOT, otherwise i would leave it.

Under Polish road regulations this would be an illegal modification. This is the reason I have decided for the second caliper version which operates on a totally separate brake line.

Sorry, but I disagree with a thrust of your comment.

You are - in principle - correct as far as the technique goes but ...

Any time you use a brake it slows the car down. This is what breaking is all about (almost). "Almost",  because braking also serves to transfer the weight to front wheels (to increase traction) as well as to position the car in the curve itself (typically just about the middle of the curve). BTW: braking in the curve is a no  no on a civilian car not prepared for rallies).

The handbrake is however used to loose traction on rear wheels , where you do not have enough space to perform normal left-right-left-right sequence ( or when the traction on the rear wheels to too big to swing it sideways when you need it.
 
Vary useful as you can make a quicker turn when the curve is somewhere between 300 to 360 degrees.( "swipe" with your rear end - so to speak).  

Also , applying brakes ( both by foot as well as by a hand) does not mean you have to take off your foot of the accelerator...

Nevertheless this kind of advance driving technique is not a natural driver's behavior. Be warned: do not try it on a open road, and train a lot (on closed roads only !) to muster it , before you start using it. It takes years of practice to do it safely and instinctively.

Remember it was developed by people like Rauno Aaltonen, who said that he trains all day at least 100 days a year (by trying all day to set a Mini Cooper on the roof).

The other of the two is in my car !


A real McCoy !

Could not be happier with it , but if you have just a civilian 131 or only a look alike replica you do not need one. For a gr 4 replica it is a must (unless you opt for the later (in-line) gr.4  homologated version.

Good to hear you like it. Hope it serve you well and long time. When I used to rally, I used the handbrake only when the slow junction type corner was very tight and slow. Mostly I needed it for the start of the stage. Startline on snow and gravel gets very groovy and its sometimes difficult to keep it still while you keep correct revs and wait to lift the clutch.

The version mentioned above is available still.

Now also the 2nd version. You can add this to any car which has hydraulic rear brakes. Just route the rear brake line through the cylinder and you have hydraulic handbrake. Even with brakedrums, and you still can keep the mechanical handbrake if you must use it for mot reasons or what ever.  240? + VAT inside EU. Outside EU or people who have business VAT numbers 0%.
