so a while ago i upgraded the rear brakes on my 1999 nbs with the twin piston rear tahoe setup. while it does stop better i know that it isnt up to par. i replaced the master when i did the brake swap as well so here are my two questions
1. should i upgrade to a tahoe master cylinder? i am thinking that i should because the original for the silverado one was made for single piston application and now i have twin piston so im thinking the master is not strong enough anymore.
2.some say that as soon as you take off the master air finds its way in the abs module. should i bleed out the abs module with a tech II to try and achive better brakes?
other mods to the brakes are: cross drilled and slotted rotors, ceramic pads, and stainless steel lines.

 

hydro boost....

first i would get all the air out and see if that helps.

 

i want to go hydro boost but im selling the old girl soon and upgrading to a silverado ss so im just trying to get a nice strong pedal. i bleed out the system (but not the abs module) agians yesterday and it didnt feel any better.

 

Doing the automated brake bleed with the Tech 2 or Snap On scan tool usually makes a noticeable difference.

Some times I have had to do it 2 times to get Sufficient results But I am supper picky as well...
