Cylinder? I know it isn’t the pads or the calipers since it worked before.

Car is a mid 80s Toyota Camry my Dtr bought and hasn’t been driven much in past 6 months due to covid and college. She is getting ready to go on mission and we have had a couple people drive by and want to buy it. She leaves in 2 weeks and I need to fix it.

I have worked on brakes, replacing pads on cars and checking and adding fluid (she has plenty). Also worked on bleeding brakes on motorcycles, race karts and mountain bikes. I am not sure if it is all that different.

My first instinct is to try and bleed them. If that doesn’t work, then look into master cylinder?

Any thoughts?
