GGGGGGRRRRRRR transmissions suck

so i shop told me to put brake fluid in the master clutch cylinder
so i did and it was working fine
now i have to do that on a daily bassis to drive it (only transpertation)
and it leaks brake fluid all over my interior and my pedals are all slippery and its a mess
what is leaking???/?
i took it to a shop and they said they had to replace the whole hydrolic system and that was goin to cost me $550 i think there jus scammen me but idk is this something thats easy to fix or will i have to go to a shop becouse itll be a while with a minimmum waige job

Check the rear seal on the back of the master clutch (where the pedal is). Your gonna have to take the pedal off to check it. Its two bolts on the fire wall near the top of the pedal (interior side). After you get those out take the lines off the master clutch cylinder, then you should be able to take out the clutch master. To check the seal id put some fluid in it after its out. Then just hold the hole where the line went and press the pedal in. if it leaks just go get a good one from the junkyard. A mechanic that wants to charge $550.00 for that is a rip off.
