hydraulic handbrake

do I just put the hand brake inline with the rear brakes?

I'm not sure I understand the question.... A hydraulic hand brake will require its own master cylinder, brake calipers, and lines. It is completely independent of the main braking system.

I have head of people running them inline though

They just go inline of the existing fluid line to the rear brakes. Cut and use a joiner on the existing line, one side goes into the handbrake master, the other joins back up to the existing line to the rears.

Existing line is M10x1.0 and bubble (metric) single flare if you just decide to remake the line from the proportioning valve.

If you just cut into the existing line, you pretty well have a choice of flares, just need to match the brake nuts with the joiners. Id suggest you go double flare as it's easier to get a good flare on even a cheaper flaring tool. Then you'll need brake nuts to match the flare on your handbrake master which is most likely going to be -3AN. Standard brake line is normally 3/16. Ask them about the quality of the line. The better quality stuff can generally be bent fairly easy by hand and is pretty pliable. Makes it easier to lay out and run. The other stuff can be so stiff you absolutely need a tube bender to get it to do anything remotely like you want it to. Even then it'll be a huge pain in the arse when you just want to give the line a little tweak as you'll either have to remove the line or try to fit the bender in a tight space.

You can get hydraulic hand brake setups now which have a locking mechanism so it functions like a park brake (e-brake).

Get some "P" clips to mount the lines with too. Plastic ones are good and can be fixed in place with just a rivet, or use some rivnuts/nutserts and a bolt. Space them every foot or so to keep them from vibrating around. Be surprised how much the lines can flex in use. Run them all the way back under the car to the joins.

Okay thanks for the reply and would this compleley replace my existing ebrake or should I keep the original one and my car has drum brakes would this effect anything

[Madhatter]

If you got one of the locking ones, it could completely replace the e-brake as far as use goes.

However, you have to realise that if you have a failure in the hydraulic system somewhere, you won't have a hand brake to stop you. The existing handbrake works off a cable, doesn't need fluid to operate the park brake (e-brake).

I am sure he is using a hydro setup for either drifting or rally.

[Madhatter]

Yes, but what I am saying is, if you replace the existing hand brake and just use the hydraulic one, if you have a hydraulic failure you will not have an emergency brake you can grab to stop you.

If you drive the car in situations where that could be a problem, its best to keep both systems.

Okay thanks for the help😃

I'll just jeep the stock e brake too because interior will look nicer all complete
