Ok when i was driving home tonight from work it seemed like i had to push on my brakes harder and farther than usual.

Like i had to push the brake pedal down about half way before it started to slow down and almost 3/4 till it started really slowing down.

When i got home i checked my brake fluid, it was alittle low but not alot So filled it up. Started car sitting still and if i push the brakes down it will stop and then go to the floor but still with pressure.

All the pads and rotors are good. A month ago my right rear Caliper Braket Sliders Froze so i replaced it, Then about 2 weeks later my left rear caliper slider froze. I replaced it too. (thats why brake fluid was low) But that was almost a month ago, i just noticed this tonight. Or is this normal and i just havnt been payin attention. ITs not leakin brake fluid. So it makes no sence why this would just start.

 

Run the car and start pumping the brake then run car back and check if its leaking, it can be wheel cylinder,
Is the pedal working harder than before? Then it can be servo... (Its easy to check, just push the pedal as hard you can on turned off engine (Keep pushing the pedal), then turn it on, pedal should go down, if not - its servo ;])

 

Ok, but if i turn it off and turn it on and the pedal goes back how do i get the pedal to come back up. lol Where is the servo at.

Sounds like stupid question but if it goes back down will it ever come back up. Im pretty sure its not leakin, I filled it back up and it seemed the same.

Now awhile back when i went to jack my car up i hit one of the brake lines and crushed it it. But its never affected it. All the brakes been working cause it didnt crush all the way in. I didnt want to squeeze on the side and break it so i just left it.

Just makes no sense that it just started cause i havnt done break stuff in awhile.

Idk if it makes sense but it just dont seem like its grabbin fast enough.

 

I think you dont understund me,
Turn off the engine, then push the brake pedal down and keep holding it all the time, then run the engine (still holding the brake pedal), now the pedal should go down lightly, if its not then servo is down.

And tell me, the brakes are working harder then before, or same as it was?

It should automaticly go back up when you release pedal . its not?


Servo is the B on the pic:

 

Ok i got you, Yea like if the cars off, if i pump the brakes or something then the brake petal gets stiff and then when i start it the brake pedal gets soft again.

The Servo is the brake booster right?

But if say if i push on the brakes while started it will go down and stay hard then after acouple of seconds it sinks to the floor.

 

Yes, it is brake booster

It may be the servo problem but im not sure, you told me that when you run the car, pedal is going softly down, so its working, But
Its possible that brake booster is working wrong...

What if engine is hot, its still working the same?

 

Yea it was like this all the way home from work (25 Miles) I drive a Very Curvy and Hilly Back Roads and it just seemed out of the ordinary tonight like i said i had to be pushed about half way before i got anything.

 

So i have no other idea, you have to wait for someone's other opinion or just go to service and ask wtf is going on ;]
