LT1 Braking issue Alright, I am going to try to be as descriptive as possible without trying to overwhelm anyone.
97 Trans Am - 4 channel ABS(deleted)
LS1 engine
Slicks and Skinny tires
Brakes:
Stock LT1 calipers, rotors, pads.
Ever since I deleted ABS I feel I have had less than perfect brakes. Unfortunately with taking the car off the road in 2009 I can not remember how the brakes worked. When the car went on the road in 2010 it seems the brakes were only 30-50%.
Last year this really started to bother me with having the power my car does, and not full braking so I started working on it.
Since I have:
Replaced master cylinder with 3 master cylinders
Replaced all flex lines with Techna-fit Stainless lines(all 6 lines)
Re-bled gallons on fluid threw the lines
Deleted line lock(make sure it was not causing any issues)
Turned rear rotors and took any glazing off the pads
Deleted Power booster and went with a BMR manual master
Current configuration of brakes is as followed:
Lt1 calipers, pads, rotors
ABS deleted (T in front, T in rear at firewall with 2 lines still running back)
Line lock on front
Proportioning valve on rear
Strange Master with rod moved 1" up on pedal
all new Dot 4 brake fluid.
From the assisted brakes to manual the car does not seem to stop any better or worse. If anything I feel I can push the pedal harder to get the manual to bite a tad more. I would assume I should be able to actually hold the car on the line / brake either the front of rear of car loose if the brakes actually worked.
What else can I try? It has been 2 months this year so far that every night I have played with them for a hour or 2. I just want to drive the car and feel safe.

Gotta make sure your brake bleeding procedure is down to the tee..
