Thoughts On Brake Booster Delete For My BRZ
 

Hey All,

So I am on a quest to reconstruct my wiring harness, and in doing so, found out that Subaru thought it would be a good idea to bird nest every fucking connection possible into 1 harness.

I am doing my own racing harness with TXL wire, Raychem loom, etc, and all while going about this project, noticed the wiring is behind the brake booster, attached to the brake lines, and is a pain in the ass to remove without removing those lines and/or booster.

Having said that, I figured that if I'm going to go that far, this might be a good opportunity to install a Chasebays dual-piston brake booster delete.

Not sure if anyone here has done such a thing, if so, I'd love to hear your feedback.

For everyone else, I'd like to hear your thoughts and/or suggestions as well.

Thanks in advance!

LoL, so yeah, I went ahead and purchased everything...

What will happen to the VDC control module now that I dont need it for the brake lines?

Like, do I just plug the brakeline connectors up and plug the harness clip back in and throw it in my glove box now? LoL

Any info would be greatly appreicated!

Thanks!

What are you doing with the car? If you can live without ABS go for it :iono:

Trying to build this baby across all spectrums...show, go, drift, drag, audio, lol

I've put a lot of blood, sweat, and tears into this build, but most of all, money! haha

My ultimate goal would be SEMA. I know that sounds far-fetched, but dreams are achievable.

A funny thing just happened as I just got off the phone with my buddy/tuner, and I advised him that I went ahead and purchased the Chase Bay's dual caliper delete kit, and he was like, "Oh yeah, I was going to mention that!"

So not sure if that was a universal sign, but I'll take it.

He basically stated keep the brain, relocate it.

So I'll just go ahead and plug the brake line holes with filler head studs, lengthen the wires a bit, and tuck the VDC module somewhere out of sight and out of mind.

I have been looking at the booster delete and chase bays say that you can retain abs. Just fyi incase you want abs for streetability.

I was just thinking about that being a possibility since the pump is what does the abs work.

No booster no power brakes ABS is an after thought.

What do you mean? The booster doesn't drive ABS. This is easily tested by unhooking the vac line from the booster and finding that ABS still works.

In either case, if you're driving this car you're going to want to maintain the booster and ABS. This is a holy war topic in a lot of places on the internet, much like oil or brake pads.

That is what I just said..
ABS IS AN AFTER THOUGHT
IE The booster doesn't affect ABS at all AFAIK :iono:

That is some odd word choice in this context, but hey, you do you, I apologize for misinterpreting.

i'm reading this thread to try to better understand.

i read the whole 'ad' of the chasebay's manual master cylinder.

now the opposing side. why would i want to maintain the booster?

Yeah, I assumed everyone would see where I was coming from but the more I shop this thread around it's real hit or miss.
Apparently it's highly dependent on knowing how a cars brakes work.

And oh, BTW, here is my project build thread...if anyone is interested?

Booster will provide vacuum assistance to reduce pedal effort, if you build the same pressures, this would not affect the upcoming systems. Be sure to build new lines with similar route as the original. Do not change the abs unit location.

If the dual piston master cylinder has any adjustability, this would crash with the ebd logic from the abs unit.

Quicker 0 to full pressure, less force and travel required, not messing with the stock bias and abs logic, maintaining position for a MC brace

I still have my booster, but I did delete abs about a year ago. I've done about 5000 miles of street use with about 1000 miles of that being in the mountains near Tail of the Dragon. When I first deleted ABS I was able to lock up the brakes very easily, but after putting a few miles on the car it feels normal and I haven't locked them up since the first week or so of the delete.

Why would you remove the ABS?

I was informed that I will still have the option to run ABS, even with the brake booster delete kit.

Either way, we are a long ways from that boys...I've still got a long way to go to see that part.

I just ripped the passenger-side wiring harness out from the firewall, and that was not fun.

And oh, for things to make more sense, please see my build thread...

Yeah, I'm with that!

After further thought, I'm gonna need ABS, especially if I'm going to have all this HP.

I am just thinking of the cleanest way to mount it without having it in my engine bay.

I may end up hiding it where my huge as wiper reservoir was...I mean damn, that tank was big enough to wash my entire car LoL.
