New front pads and rotors seem to have less stopping power

[Quicksilver]

Dealer replaced them on Monday. Strange........... Maybe it's just me.

maybe there is air in the line, have them bleed the lines againg an make sure you fallow the instructions on the front page ofr new rotor beding process.

Looking for "Bedding" on google.


"Bedding allows your brakes to reach their full potential. Until they are bedded, your brakes simply do not work as well as they can. "

Give them a bit of time (miles). New pad and rotors don't perfectly mate up flat until you use them a bit. Going through a bedding procedure will speed up this process. Until then the contact area is less than optimum.

Yeah. I know your right. Their new. Just had to get use to the newness and the brake in time. I snooped around and found some additional info about the process.

The procedure to break in the brakes varies among pad manufacturer. The instructions that come with the BMW pads strongly advise against aggressive braking or "dragging" the brakes to speed up the bedding process for the first 125 miles. So, contrary to all that you've heard, you don't do anything special to bed in BMW OE brake pads. Just take off slowly, test the brakes to make sure the car will stop, and then go for a normal drive at reasonable (residential) speeds, using the brakes only as required, letting them cool down between uses. The instructions also point out that braking performance will be lower than normal until the pads are fully seasoned. For what it's worth, my technician always told me to take it easy on the brakes for the first 250 miles.

Seems like a reasonable explination to me. http://www.dvatp.com/bmw/articles/brakes_diy/

Yeah. You are absolutely right

I think the controversy over the whole bedding thing arises from the fact that different pad materials have different break-in requirements. OEM pad material is very different than some after market "performance" pads. Bottom line is, follow the instructions that came with the pad and don't use the procedure for one pad on a different pad.

WOW, it's great to see the bedding in brake pads nonsense is finally getting some coverage. I have been posting about that for years. It’s good to see some of the DIY writers are not endorsing it anymore.


Let your brakes normally break in… best advise you can get IMO.
