My 2006 mercedes e500 brakes are squeaking when I brake. Does this mean I have to replace the brakes?

if it is a scratching /squeaking noise then I would look at the brake pads as it may be an low pad indicator touching the disc rotor telling you that the pads need replacing
It may also be a loose wheel bearing
A noise is not very descriptive when wanting answers to problems.

Did it make the noise and THEN you changed the pads? Or did you change the pads and then it started making the noise?

If it started after changing the pads, try sanding the pad surfaces lightly with sandpaper. If they are too smooth, it will cause a squeak.

check your brake, or clean your brake, or replace your brake pad may be it is no more brake lining,

it may mean nothing, squeaks from brakes area not uncommon. on the other hand, if the noise changes when you apply the brakes or if you just haevnt had the brakes inspected latley, it could be the wear indicator rubbing, this means the brakes are at the minimum thickness and should be replaced

Hi Chery, squeaking from the brakes isn't at all uncommon. The simplest and most likely cause is dust in the braking system. This gets between the fristion material and the disc or drum, heats up and creates the sound. Going beyond that, it might be a lack of lubricant (special grease) bwtween the disc pad (or brake-shoe) and the actuator/s. Worse still it's possible it's indicative of worn out brake friction material in which case it could well be the base of the pad or the brake shoe rubbing against the disc or drum. This last will entail a brake overhaul - fitting replacement pads and/or shoes, and if this has caused disc or drum wear, their repplacement too. Good luck!

If the rotors where replaced during the brake job this is possible, it could be that the hub always has been bent but the previous rotors where skimmed on the vehicle thus eliminating the brake shudder. If the rotors wherent replaced in the recent brake job, the chances are unlikley the the hub suddenly warped.

If the brake wear light on you can't reset the light without replace brake pads and sensors inside the pads must replace both after replace it will off automatically

if the caliper is loose that means one of two things. Loose bolts to the caliper or a sticking caliper piston

the wrench means its time to change the oil and filter, the squeaking sound might be the brakes, it has a squeaker on the brake pads when they get worn down, the squeaker touches the brake rotor to tell you to get your brakes fixed, hope this helps,thanks robert b.

There are a numer of reasons brakes will squeak or squeal. Sometimes excessive dust acculation wll cause it, yet another cause is the TYPE of material the brake shoes are made of. The harder the brake shoe material , the more tendency to squeak / squeal. My suggestion is use high quality brakes such as OE brakes. Hope this helps.
