I saw that my master cylinder was leaking and was losing pressure so i replaced it along with a slave with duralast psrts. Worked for a week then the lost complete pressure out of no where. I bleed the system. Didnt build up pressure so i decided to replace them again. Didnt work i bench bleed the master. Didnt build up pressure again. I used a one man bleeder with the help of a friend. I don't know what could be the problem if the parts are new. I cant see any leaks in the lines. The only thing i could think of is to put in stainless steel braided lines to replace all of the hard lines. Does anyone know what the problem could be and how i could solve it before i put more money into this car?

 

see if there's a uv dye for it, also how is the clutch pedal behaving?

 

i havent tried pytting uv dye in it. After the second time of it not working, the pedal has no pressure and drops straight to the floor. After replacing the master, slave and bleeding the system, the system just doesnt build up pressure so rhe pedal still drops to the ground. After bench bleeding the master the pedal felt a tiny bit better as in lightly touching it doesnt make the pedal sink to the floor. Still though bleeding for an hour straight didnt work so my assumption was that theres a leak in the line.
