Feels like I only have some brakes
The car stops but not as quick as before. I feels as if only the front brakes are working. The brake pedel has to go lower to stop and then it takes more pressure. Master cylinder? Booster? Where do I start?

Start by checking for the proper brake fluid level in the rear brake portion of the master cylinder reservoir. And let us know a little more about the vehicle-model, year, etc.

The fluid chamber for the rear brakes is hard to see. It essentially is filled when the front chamber overflows. I would suggest topping the reservoir just to make sure that the rear chamber is full. This setup has fooled more that a few MB owners.

My guess is that your master cylinder is going. Mine did the same thing your car is doing and I had to replace it. Though I was certain it wasn't my rear brakes because I had just replaced the rotors and discs and flushed them a few weeks before the master cylinder started acting up. If it were your brake booster, you wouldn't be able to depress the pedal much.

Both chambers are full. I learned the hard way about 2 years ago when I was bleeding the breaks and going nowhere fast until I noticed that there were 2 chambers that had to be filled. Is there anything I can do with the master cylinder in the way of rebuilding? If not I will take a trip to a pick and pull to see what they have. Does anyone know if MB used the same part for different models and also what years?
