when i did my swap i removed the front brake lines and let them just sit there. well i bleed my brakes and the other day my brake pedal sank to the bottom. i had to pump it to get pressure. well now it is going all the way down but i stil have a little brake but not enought to stop me fully. i have a 94 ex with abs but i took the abs unit out. well i had midas bleed my brakes and they were fine for about two minutes. then they started to do it again. are they right is it the master cylinder and what can i do about it? and can i use my eg9 master cylinder and/or brake booster?

 

they are correct. the master cylinder needs to be replace.

 

how much fluid are you using/loosing?

 

Id upgrade to a ITR 1" MC.

 

whats the differ and is it easy to put on or should i let them? can anyone tell me how to do it

 

what car you have? i got a brake booster off my car 92 hatch cx
i replaced mines with a type r one so i dont have any use for it.

 

to check if its the master on your own, line lock all the rubber brake hoses, 4 total feel the pedal in the car if it still sinks its the master if it holds tight it may be something else.
