S14 Zenki vs. Kouki OEM Brake Boosters (USDM)

[S14rebuild]

^ wow thats good to know..never knew anyplace that rebuilt them and always expectes to buy a used one if mine failed. The price seems decent for anything that is a specialty job in the auto world. Excited to see the end result and obvs longevity....

U should ask him if he could document some pics, just to see the internals and the condition after all the years and miles..would be a kool sight..atleast to me

haha yea I never knew it existed either until now lol. Price seems fair; I figure 1-2 hours of labor plus parts?

It's cool -- maybe I will take pictures of the old parts after he finishes working. I don't want to interrupt his normal workflow or whatever

Aright, so the shop has finished rebuilding the brake booster. So, 1-day turnaround time for this one.

They said that they changed all the seals and the diaphragm. Likely what happened was that I had a leaky bmc and the brake fluid got in and rekked the brake booster over time. (current bmc is ok, but I did have a leaky one sometime ago). Ah I asked about the old parts, but they were in the trash somewhere and I didn't feel like making them dig through it.

$150 done deal 1yr warranty with receipt. I'll toss this back into the car on Friday and see if it's working properly. So far so good though.


That's the old paper gasket on there. I'll probably cut a new paper gasket using some material I bought from Autozone a few months ago. I don't think it actually holds pressure; probably just helps to keep dirt / fluids from reaching that rubber boot.


So yeah, looks like they even repainted the whole thing, which I didn't expect. But that's pretty sweet, man.
