hey, my 90 crx si with DA braking system is making noise.... any clue??? it makes this hissing noise when i drive it fast, but when i start braking, the noise slowly stop. the other thing is when i hold the brake, it slowly starts to go further in... i bleed and rebleed... nothing... any clue??

 

you can bleed it all you want...look around your master cylinder...brake booster..any moisture? if so this could be the problem.. b4 u bleed make sure u look around and see if u have any moisture anywhere on any visible brake lines, master cylinder, wheel cylinders, and brake booster.. i had the same problem til i weeded it out and changer the master cylinder. now i need a new booster. took me 5 bleed jobs to figure it out.. good luck bro, i cant help u out with the noises, ive been having a ratlling noise in my brakes for 2 years and they work fine.

 

ohh o.k.... i'll check the brake lines and stuff... and the master cylinder...
