Ok. My 93 XFi has had a lot of work recently. I put on new rotors and pads in the front when I bought the car and put in some new fluid. The other day I got in the car and started to drive it and when I needed to stop it didnt. Pedal went right to the floor with ease. So got back home and parked it. Didnt seem to me like it was a broken or cracked brake line. So I called a friend and they said master cylinder. Which was my next idea. Its replaced. Just installed it. And put a new vacuum hose in that was shot. Looked like it went from the booster to the engine. So I thought that was it. Nope. New fluid in...its not leaking. It stays full. New MC and new hose. Pedal goes straight to the floor and absolutely no braking what so ever. Theres no fluid leaking any where on the garage floor. Any ideas? Should I bleed the brakes? The resevior was dead empty when I replaced the MC. My buddy says it leaks out the back of the MC and gets sucked into the motor and burned off when the MC is going bad. So I replaced that today and I havnt bleed the brakes yet. I was hoping that the brake pedal would get evan a little stiff. But maybe if there is a ton of air in the lines I could be wrong. Anyone have any ideas other then bleeding the brakes? |

You have to bleed the brakes. There is air in the system. Edited by iamgeo, Jan 16 2011, 03:18 PM.

No stopping power?? Sounds bigger than air in the lines to me ... but try bleeding it nonetheless. Thats standard after changing those major brake components

Thats what I am thinking. But what else could it be? I will go down here soon and bleed the front brakes at least and see if it helps. But There is NO braking what so ever. It goes straight to the floor and the car just keeps going. its terrible. |

Thats why a said it seems you have a bigger problem. You should at least be getting a spongy feel when the brake is pressed rather than no braking at all if air in the system was your only problem. Check for a busted brake cable ... |

That could be....but my fluid was leaking before. So at least I have a new MC. I will go check that now. Hopefully thats it. |

Isn't there a rod that goes between the master cylinder and the brake pedal? Did you put that in? |

I just bled the front brakes. WHen the car was off the pedal was stiff like it should be. I started it and it got squeshy again. But better. And I took it for a ride and when the pedal is down on the floor basically it does slow the car down and stop it. So I am warming up....I live in western PA its like 20 degrees out side. I didnt want to get brake fluid on the garage floor. Just cleaned it lol. I am using a bottle to catch the fluid coming out so its not all over the ground either. But just in case its in the drive way and not the garage. Now I only did the front. Then I will go back out in a few minutes and do the rear. Then probably the front again. There was deff air in the lines. So I will now do the rear and see what happens. Thanks for your input guys. Can always count on this forum for all my Metro needs! |

What ever was there is still there. All I did was remove the MC and put it all back together the same way i took it apart. So not sure exactly what rod your talking about. Any more info would help hopefully. |

If you are now getting some brake pressure the rod is in there. You need to bleed the brakes but you should do it in a specific order. Right rear then left rear, then right front then left front. Did you bleed the master cylinder? |

Oh ok. Then that order is what order I will do it in. Is that looking at the hood or the hatch? I am assuming the hatch. It would make send the left passenger side would be the farthest away and longest line. What do you mean by bleeding the master cylinder? hows that done? I guess I didnt do that. |

How to bleed brakes How to bleed a master cylinder The MC can be bleed on the car. No need to remove it. Since you already started to bleed the brakes you may have already pushed any air from the MC into the brake lines. Be sure to get all the air out. |
