thinking i might build a hydrualic handbrake as mine doesnt work atm and id like to know how it works/ build one....
any tips?
what have you used for your hydro setup?
good parts to use and where i can get them?
Get yourself a master
Get yourself a master cylinder from anywhere you can, preferably with a remote reservoir. That way it should have a line in (from the reservoir) and a line out (to the brakes). One from an older car is better as the new ones will probably have a twin circuit.
You then need to ditch the reservoir. It's not used. Find the line to your rear brakes and plumb it into the car. The line from the front of the car goes into your reservoir connection point and the output is connected to the line that goes to your rear brakes.
The idea is for the new master cylinder to be "in line" with you rear brake line. You need to mount the new master cylinder and use the handbrake lever to push the rod that normally is connected to a foot brake pedal.
The only thing you may find with this very simple setup is if you have pulled the handbrake on and then jab the brakes (with the foot pedal) it may rip the handbrake lever out of your hand. This is the footbrake activating the brakes in the rear wheels, most likely with more force than what you will apply with the handbrake.
Typically you will use one or the other, so it shouldn't be too much of a problem.
As a rally driving man once said:- "Brakes are for slowing, trees are for stopping!"

That quote sounds familiar
That quote sounds familiar bro.
The master cylinder you use HAS to be a cylinder that is made for high pressure in and out otherwise you will blow the seals out when you use the foot brake.
the last one i built was a proper one for a hydraulic handbrake, it has a banjo fitting in and out, price one up thru the rally shops. and make the rest. or from memory perth breke parts may have sold them
perth brake parts will do a
perth brake parts will do a cylinder for around 90 bucks from memory. with fittings, the hard bit after that is borrowing or buying a flaring tool.
veals will do one for about 100 dollars i think.
Brent who works at Perth
Brent who works at Perth Brake Parts can get the bits for you. You could buy a cylinder from Aarin for $90 or you could buy one direct from Brent for $70 :-) Brent has entered Sunday's Khanacross in Kenny so track him down and have a chat to him.
