Bloody squeaking brakes

Will these damn things EVER stop squeaking? jesus is it annoying.

Brand new mb rotors up front with akebono ceramics. MB lubricant used on the pad backs, the bolt/slides and where the pads sit in the caliper brackets.

Same situation out back with the exception of EBC red pads.

Did my best to bed them in properly.

yet at light pedal application they squeal like a baby seal being clubbed.

Any other suggestions to get this crap to stop?

Thanks

brakes

This is very annoying for me as well. My wife opens the door to the house when I pull up because the brakes make enough noise for her to hear from inside the house. This does not make sense to me.

When you figure out a solution let me know. I have brand new brakes, all parts from mercedes and it squeaks, suspension moves slowly, it squeaks. I swear to ___ that my 740il back in the day was a quiter Sedan stnading still. But you know, with the doors closed. you dont hear crap and on the interstate it is the quietest machine I have ever drove on the road. Even less than and smoother than a Bentley Mulsanne S. Is kinda embarrsing though to pull up to some places sometimes and people are looking at you like WTF

Squeaks and noises may be annoying
But I love this _____- CAR

Oliver do the EBC and Akebono breaks have the same Break in procedure?

I heard you need to drive faster and break harder to warm up your breaks to stop the squeaks.

Akebono brake pads are post-cured (pre-broken in), the EBC's are not. Though it is a good rule of thumb to follow prescribed brake break-in procedures. I always suggest at least 1 tank of fuel, extra braking distance, and the 2 second following rule should always apply.

He's right I have Akebono on both of my cars and simply no dust , brake feels smoother and a stronger stopping power that won't quit like the OEM Pads felt before .

i usually use the spray on brake quiet compound on back of the pad and all sides of the pad shim plates. No squeak problems at all on my ML and S. They both use the same front brake caliper.

Not always necessary, check what the recommendations from your brake pad manufacturer are. Akebono pads come with their own pad lubricants as do many others. Many Wagner brake pads have shims/backing plates built into the brake pad for the simple reason to prevent shim or backing plate failure (i.e. falling off).

That could be true of any brake pad ceramic or not. But ideally no brake pad should start to make excessive noise from temperature changes considering the brake pads already experience huge temperature changes from just simply stepping on the brake pedal.

Okay here is EBC's bedding process from their site

use the brakes on a quiet and safe road 5-6 times at medium pressure bringing the car from 60mph to 10mph. Drive the vehicle for a few miles to allow the brakes to cool and repeat this procedure. During this final break in a brake odour will almost certainly appear and this is perfectly normal. This is known as green fade where the surface resins within the pad finally cure and burn off.


If you read the instructions, it will vary a little.

My own, squeak free bedding is as follows:

Change brakes and USE anti squeal greese please.

Go to an interstate, make 8-10, 50 to 10 mph fairly hard slow downs, caution DO NOT COME TO A COMPLETE STOP while doing this. The idea is to get the brakes VERY hot without fading them. Note: You WILL smell the brakes in the car during this procedure which is normal. This burns off ANY break in coating, and allows the brake material to get up to operating temprature to bake them, aka harden them. After you have made these passes, continue driving for atleast 10 miles WITHOUT using ANY braking, or as little as posiable, aka allow them to fully cool down. Drive the car home and allow to sit overnight. DONE. I have used this procedure with with ALL brake brands, and it works like a charm. It was an old racer trick at the track when changing out pads.

Note: For rear axle, use the energency brake while doing your slow downs, and reduce the speeds to 40-10. The rears CAN'T take as much heat as the fronts, aka smaller surface area. You will also need to do LESS slow downs with the rears 4-6. But same rules apply, and DON'T fade the rears, which is easily done at higher speeds while using the E brake.

Give it a shot.

See yeah

NEVER had any squealing after this I might ad.
