Do I need to start saving up ?

On Honest Johns site he say this regarding the current A class.

Brake discs only seem to last about 3 years and around 25,000 miles before dealers advise expensive replacement.

.
I have done about 24,000 miles and discs are showing a distinct step at the edges and unevenness across the face. I always drive gently and avoid fierce braking. Surely discs wearing before the pads is a fault, not normal wear.

The thing to do here is to measure them, the min thickness is stamped in the center

i have noticed that since asbestos was removed from brake pads that disc's wear as quick or quicker than the pads, the last car i had that used asbestos pads the disc's were still ok at well over 100000 miles, cars nowadays seem to eat disc's at about 24000 miles.

Interesting as they did seem to last longer some years back, the only consultation is that we last longer now without the asbestos

Don't know if it's just a Merc thing, but I have noticed that the discs do seem to wear alot more than on any car I had previously.

My current C-class had to have new front discs after approx 30k miles.

When I had my A-class before that I also remember having to replace the discs alot sooner than i expected. But then replacing things on the A-class became a regular occurance!!!! lol

the reason i believe, is that modern brake pads are a lot harder/abrasive than their old asbestos counterparts, giving better braking without as much fade but eating discs.

In the old days I never replaced a disk - even on a 100,000+ miler they would go strong.
These days I know that every 2nd set of pads will require a set of discs to go with them. They do seem to last longer though. I had a set of pads changed about 3 years and 35k ago and the last time I checked them they still had plenty left.

I don't see why mercs would be any worse than anything else though and especially not an A class.
Bit confused about the 'expensive replacement' bit. Merc disks and pads aren't that expensive for an E so I can only assume they are even cheaper for an A. Ok - more than a fiesta I'm sure but I'd imagine pretty comparable to a golf.

My brother's A class (169) (latest model from 2005) has done 35,000 miles of mixed motoring and the original pads and discs are fine and at his recent service they noted that the pads are less than half worn.

Don't know about the old A class but have perused many threads and not seen this problem before. Seems odd.
