Hydroboost upgrade

[Rayyy]

Refurbing the brakes in my 01 Yukon XL 5.3 after my MC just bit the dust.

It never really gave me comfort when stopping after putting on 20” wheels with 305’s, compared to stopping stock.

I’m going to upgrade to Hydroboost, as well as NNBS front brakes.

I have pretty much all of the parts needed, except for the actual booster.


Wondering if anyone has a hydraulic booster sitting around they’d like to sell?

GM part#: 15854060 , or
AC Delco part#: 178-0684

Also, I read up that it’s possible to upgrade an NBS Hydroboost setup to an NNBS Hydroboost setup... Meaning it would fit as a retrofit to a non-Hydroboost NBS truck.

Has anyone done this?
