Need some help here guys. I have a 91 civic sedan and my front brakes locked up one day while I was driving. Was still able drive the car so only noticed because car felt like it had no power and when came to stop light wheel was smoking so pulled over once I could and sat for about 30 mins randomly checking if they unlocked once they did got the car home as quick as I could and brakes were working fine pulled wheels everything looked ok and werent locked anymore but few hours later went to drive and had no brakes at all car can be pushed while brake fully pressed to floor and has no pressure but ebrake works. Has brake fluid and cant find any leaks. Going to be replacing front calipers as have known working ones available as well as pads. Any suggestions on what could be the problem here? Thanks everyone

when i had things like that happen before on old cars it was often corrosion build up in the calipers, both inside the caliper not allowing the piston to travel freely AND the slider pins were dealing with heavily contaminated grease and not allowing the calipers to slide freely...basically lack of care and maintenance.

Master cylinder and booster not spaced correctly.

Thanks guys Ill be changing calipers once its nice out and bleeding the system. If that doesnt do it Ill look at the MC and BB. Just had car in at midas for a brake checkup and had rotors resurfaced and new pads because I didnt want to deal with it later and they said everything looked good except for pads that they changed. Anything in particular I should look for while changing caliper and bleeding it?
