Hi all,

My 325is brake pedal sink to the floor EVERY time I make a complete stop. If I pump the pedal, it would work for the moment then the same thing happen again. Fluid level are fine. No leaking fluid on the ground. Have the car for about a month and this just happen two days ago. Any help is appreciated.

Also, is there a fuse for the rear mirror lights. My lights doesn't work at all and I don't have the owner manual. All the fuses under the hood are checked out O.K.

either bleed the system, or your master cylinder went bye-bye.

I think my car's master cylinder(s) gave up on me. It is unlikely to have air bubles in the brake line all of a sudden. Thanks for the pointers "EVOIIIM3".

Just check the flexible hoses too. Air can enter the system from within the hoses.

I replaced brake master cylinder and checked all horses and it's still bad. What now. Please help. Thanks.
