Hello everyone, I have a 2006 Chevy Cobalt Ls and I love it so much. My dad gave it to me and it's my first car I've ever owned so it has a lot of sentimental value to me. I recently installed a rear axle with disc brakes on it and now I'm having an issue with the brakes where I have to almost slam them to the floor in order for them to engage. I replaced the brake fluid twice, replaced the master cylinder and even adjusted the e brake but the brakes are still squishy. I don't have ABS if that helps solve the problem. But any help would be greatly appreciated!
