      the brake pads or discs get wet when you get your car washed. this might be the cause. just pump the brakes to dry them, it should just work fine afterwards. is this the only time that the brakes fail? if there are other instances get the brakes/lines checked, you might have a leak or air in the brake lines.

      Check these possibilities; faulty light bulb, faulty wiring or connection for the brake light. There is no separate fuse to check for the single light - same circuit as the rear stop lamps.

    My brake pedal soft after I had the brake fluid changed.
    I had the brake fluid replaced in this car, per Mercedes recommendations, and the brake pedal became soft. I thought there might be air in the line, but the garage says no. I have to push the brake pedal down a considerable distance before the brake engages, and ...

      Have the brake system bled of residual air - sounds like the brake system was not bled properly.

    Brake Line leaking!! How many brake lines does Benz 300 have? Left or Right? Front or Rear?
    I paid to fix the 'left' line leakage barely 6 months ago, now, I am told that the right brake line leaks compromised by the breakage of the rear spring-coil!??

      Possible air in brake line. Try Bleeding. Another possibility is the anti lock metering valve.

      First off check that the vacuum hose is connected to the brake booster. Second, ensure the check valve that connects the brake booster to the hose is oriented correctly. It's a one way valve. If you pull it out, the side that you try to blow through that doesn't allow air through is the side the vacuum hose connects to. Similarly, if you apply suction to that same side, it is the side that connects to the vacuum hose. The other side connects to the booster.

      If all of the above is well, your next step is to listen for any hissing sound, particularly inside the vehicle cabin. With the car running, step on the brake. If the pedal is stiff and you can hear a hissing-suction sound, then the brake booster diaphragm has a tear in it and needs to be replaced.

      Ensure that all air in the brake system has been bled out. Keep reservoir topped off during any bleeding process. The most basic bleeding process begins with the rear right, then rear left, then front right, then the front left brakes. It may vary on your vehicle, so make sure you look that up.

      Ensure the seal that connects the reservoir to the master cylinder is intact and not leaking. Likewise, ensure the seal for the reservoir cap is also intact. Check all brake lines, caliper and wheel cylinder bleed screws, as well as caliper and wheel cylinder pistons for any dripping fluid. For wheel cylinders, it is normal to have a small amount of brake fluid on the end near the pistons--it is ok for it to be slightly damp with brake fluid, but any dripping is not ok.

      If utilizing drum brakes, ensure the adjustment is correct. If the adjustment is too low, the shoes will not contact the drum, and your brake pedal will drop to the floor.

    How much is a tune up kit?
    I need a tune up.

      Impossible to quote until a mechanic looks and sees what is needed. They do not sell "tune up kits" anymore. Mercedes Benz is not like other ballpark estimates on other cars.

    My abs light turned on when my mechanic did an oil change/service a. Do i need to worry about it.
    He didnt have the key to reset it in the computer?

      Doing an oil change will not cause an abs fault nor can I even remotely relate it to an oil change. Only *reaching* thing I can think of is if the lift made contact with an abs wheel speed sensor wire that was already dangling and got crushed (seems doubtful) or if just the car being lifted off the ground with the suspension being allowed to fully extend has been known to cause an issue rarely. I have nothing more... There is no worry though. With the abs light on you do not have functioning abs which is certainly not a danger seeing as how cars had no abs through around 1980 about.

    Short intermittent grinding noise from the front tire. Braking, nor turns makes difference. Only above 10-20 mph
    Hi, my 2009 C300 at around 52K (no longer under warranty) has a short intermittent grinding noise coming from the front right tire. It only starts at about 10-20mph and its not constant. It's as if every time the tire turns, it is grinding against one specific spot ...

      Check the following; loose front brake caliper mounting (loose / missing mounting bolts or hardware) - to allow the brake caliper to move or flex during certain turning or braking conditions. Also, look for a lose / worn front wheel bearing. To thoroughly check the front brake caliper - you will need to raise and support the front end, make sure the front wheels are clear of the ground, and then remove the front wheels.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the front brake caliper guide pin / bolt kit from around $5.00 (axle set left and right sides) for your vehicle.
