I recently posted a thread saying that my brakes on my C1500 Suburban are horrible after the nbs upgrade(spongy and hardly any braking power) . I got a lot of recommendation to go back to OEM, but as I dug deeper I saw if i swapped my current JB6 brakes for a JB7 non low drag caliper and rear jb8 wheel cylinder its should make my brakes a lot better. I am willing to go back to the OEM JB6 master as long as my brakes work but they were bad too when driving, they would stop but not very fast. I really do not want to buy another master cylinder though as i have a almost ew OEM one and new NBS one as well, and think there is a way to stop the brakes from being so spongy with these two products. The two part numbers I got from another forum indicate part ACDELCO 18R741 and ACDELCO 18FR741 along with ACDELCO 18E1362. Thank yall and sorry for the non expertise lol. I plan on knowing these trucks inside and out by the time I get mine cleaned up.
