ok guys.. i have a s14.. 95.. 160k miles.. brake i think it went out.. please can somebody tell me if this is my brake MC going out...

i bleed all the brakes.. no air in em... used 2 bottles of brake fluid to realize it was something a lil more serious... so i took it for a test drive on my street... going 20 mph.. hit the brakes.. feels like ABS.. funny thing is ... i dont have ABS... the pedal pumps it self kinda... decided to take it on the main road to the gastation to get a pack of cigs... braking at 35-40 mph to a stop feels like brakes from hell!.. the pedal pumps very aggressively... and my front wheels will move back on forth.....

when the engine is off the pedal feels awesome... when i turn the car on... and pump the brakes... the pedal fades to the floor after a few pumps...

so thanks for any replies... i just wanna know if its the brake MC.. i ordered one anyways.. just incase....

thanks again..

Sounds like you have a serious warpped rotor, or your tires aren't torqued down proplery.
When you depress the brake and it hits the floor and if you pump it a few more times to get a "feel" of the brake, your brake MC is leaking. Look behind the Brake MC to see if there are any signs of brake fluid.

what happends when you have a blown rear caliper? i replaced the MC... and when i bleed my brakes.... i have air comming out the the damn brakes everytime i go around... on the bright side.. i have a flush brake system now.. but anyways.. back to the point... when the rear calipers go out do the seals let air in? my brake lines are not crack.. or anything.. i went through the whole system... if anybody has any advice or can help me.. please let me know..

Might as well do a complete z32 brake swap (front and rear and MC)haha. 500 should get you everything if you research for where to get them. As to air enter the system, all I know is 4 calipers are connected so if one leaks, all ur brake is pretty much screwed.
