while back i had a brake hose bust...i change the brake hose and bled everything but i had to pump to get brake..well i bought a brand new booster and master cylinder, re-bled whole thing and still same thing takes bout three pumps to get good brake..can someone shine some light on this problem..and pads and rotors are new as well

 

I am presuming, but mention it in the event it is not so, that the master cylinder has been topped off after replacing the brake hose and bleeding the system?

What was the cause of the hose bursting? If it was age, perhaps all brake hoses need to be replaced?

What you are describing/experiencing sounds like a brake booster problem. It could be as simple as the the vacuum hose going to the brake booster being bad, leaking and in need of replacement? Or the brake booster may need to be rebuilt?

 

i replaced brake booster while back brand new and new master cylinder, and id say with in last 6 months ive bought 30 bucks worth of fluid n just idk anymore..ive replaced hoses, only thing left i havent done is replace calipers their selves..what are some signs of bad calipers

 

$30 worth of brake fluid? That is a bunch! Where is it going? That would be a clue. Can you see where it is leaking? Something is not tightened. Are the brake bleeder screws tight, brake line connections secure?

Hard to imagine losing that much fluid without being able to detect location of leakage?
