DIY: Hydraulic Handbrake Install

[E30steez]

Where did u buy the adapter/double threaded at that goes on the mc. And if so what's the part number?

[Jezza]

Where the unions are is basically where I tapped in. Second to last picture of the post.

[E30steez]

Have a question for the op. Where exactly did you tap the brake line and where? Thanks! Pics would be awesome

Sorry if this has been specified before but when buying the hyro e brake from ASD's website do you get the 5/8ths reservoir or the 5/8ths pass through? You said cylinder so I assume its the reservoir not the pass through, am I correct?

Lol yeah. I'll take a picture of the hydro bracket I made for my car - still not sure how I want to mount it, but I didn't think the little handbrake was gonna cut it (comfort or strength(pull strength, not structural wise).

Or you could build it :)

[jalopi]

Yes, but you'd want separate calipers in that case. Massive sells an adapter to do so, but you have to ditch your cable e-brake setup. You're looking at about $550 for a setup like that, give or take another $50.

Could you use a master that has it's own resivor? instead of being fed by the brakes?

Hmmm... the banjo ~might~ work. Just make sure you don't buy the cheap banjo adapters - a lot of those manufacturers use the same 'sleeve' for different bolt sizes, which is an issue if space or mounting surface area is limited. I ran into this issue when I bought summit racing brand banjo -> AN dealies for my PS rack. They BOTH used 22 or 23MM bolt heads. Couldn't get a good grip on the bolts, had to drop the rack again and tighten them up on the ground :curse:

Ahh OK I got it. Thanks. It would have been too easy for Wilwood to make a 7/16-20 adapter to match the outlet huh.

Also a 7/16 bango to -3an would work as well right... Thinking of doing that for a 90° bend.

Just finished figuring this out, it's your lucky day.

The outlet (3/8-24) uses a regular 3/16ths brake line nut, nothing special about it.

Wilwood can go fuck themselves for the thread pitch they used on the inlet :curse:

Line nuts that fit it do exist, but the ones I could find only existed on ebay coming from the UK. You will find 'adapters' with google searches from autozone, advance auto parts, ect and they all state they have something that will work. They do not. Their sites are wrong - they have the right part number listed, but it's actually a 7/16-24, which obviously will not work.

Here's what you need to buy for the inlet:


Adapter to go from the inlet to your brake line. Make sure you've got teflon tape and a crush washer for it as the fitting does not bottom out in the master.

Tube nut, -3AN

http://www.summitracing.com/parts/fra-581803

Tube sleeve, -3AN

http://www.summitracing.com/parts/fra-581903

Make sure you get -3AN as it's the equivalent of 3/16ths. When you're doing your flare, but the tube nut on first, then the sleeve, then flare.

Also, the 7/16-20 adapter you linked is 9/16-20, so don't buy that :D

Ok, so I'm thinking about making my own kit but since it won't come with the hardware kit i'm confused about the fittings for the wilwood master cylinder.

According to the Wilwood site, the outlet is 3/8 -24 which is ideal for 3/16 line correct? so i would only need a 3/8 -24 nut and flare the tube.
http://www.jegs.com/i/JEGS-Performan...35270/10002/-1

The inlet is 7/16 -20. So, this fitting would make the inlet the same as the outlet so i could just use another 3/8 -24 nut.
http://www.jegs.com/i/Wilwood/950/220-5248/10002/-1

I'm just a little unsure why Jezza used -3an sleaves and nuts rather than just 3/8 -24 nuts or do both work?


I'm new to brake lines so and all the fitting sizes make my brain hurt
