Braking Problem, Need 2nd Opinion

[EclipseOwner95]

Basically here is my problem whenever i hit the brake pedal, it goes to the floor, i have to pump it several times to get pedal pressure back up, and as soon as i let off again, it dies again., im not exactly sure when it started happening, i did my back brakes w/o bleeding them, and it started happening, but it also was happening when my front brakes were dying, so i replaced the front ones nad still didnt bleed them ( im a dummy ) well, i bleed them yesterday and its still doing it, but what i find wierd is that if i let my car sit for a few hours, i can get good pedal pressure for the first 10-15 min of driving, then it just takes a shit and gives out again, think its my master cylinder ? or should i bleed them again and see waht it yields ?

something similar happened to me when the brake fluid got a little low. I had a small leak that allowed enough fluid to drain that air got in the lines. i would say drain and re fill your entire system, or even just check fluid levels if you ahven't already.

Yah, my fluid levels are fine, i couldnt find any leaks, im going to drain the entire system probably tommrow if i have time and see if that helps.

bleed the brake lines, all four of them. theres defenitely an air that got in to the system. i had this problem when i took my caliper off, same exact thing happened. good luck..
