Ok so I have a problem and I havent been able to figure out I'f someone here could help me out. So I have a 1998 ek civic hatch gots a f20b turbo engine well i had to change the axles on it and while putting back the brakes one side would always lock up...so I bought new brake calipers and pads installed them and that solved the problem they wouldnt lock up and bleed them no problem...went out for a drive and started leaking from the actual caliper piston seal one side worse than the other not leaking from brake line or anything so I returned one of the brand new leaking calipers got an exchange and went and installed it but I have everything installed as soon as I tighten up the brake line the brakes lock up this is on the passenger side. The other side remains good or unlocked. Thank you for all the help y sorry for the long post. Btw the civic has the bigger upgraded front brakes from the integra or civic ex even though is a Dx number stamped 5410 on caliper
