I have a 99 Toyota Camry and recently the breaklight has been coming on and off sporadically. I assumed I had done some damage to my E-break, as the other week I tried to back out with it on (cut me some slack, I just moved to PA after having only really driven in FL lol). I wasn’t worried about it since I didn’t notice any issues with my breaks, however the last few days I randomly have to press the pedal down almost to the floor to come to a full stop. There doesn’t seem to be any consistency to this, sometimes it happens when the light is on but usually not. It does it both when I am stopped (causing me to move forward slightly till I depress it farther), sometimes when I am stopping normally, both when I’m going straight and right after turning, ect.
I checked my break fluid level and it is at the minimum line so I doubt that is the issue. I did some research and saw many saying that it was likely just air in the lines and that the system needed to be bled. But some also mentioned replacing the master cylinder so I wanted to see what response I might get on here (I don’t know very much about cars myself). I’d also appreciate it if I could get a ball park on how much various potential issues might cost. I should be getting about $300 back when I do my taxes, but I’m a recent college grad who hasn’t found work yet so I’m basically broke outside of that.
