I actually already redid the brakes... but I've never got them to feel quite right, feels like I have an air bubble in my system that I haven't been able to get out. I've bled the brakes numerous times but no luck. I was thinking maybe new front hard lines and different rear wheel brake cylinders. I think I got regular rears for 10in but I think the cars with disc fronts had different wheel cylinders.
Do the rears lock up and not the fronts during hard braking? That’s usually a sign you need have different size rear wheel cylinders. If your brakes feel soft sometimes just a brake drum adjustment fix it up.
