Break Pad Bed In Procedure

So how many people that DYI their brakes, Rotors and Pads follow the break in procedure to bed in the pads


I figure it must be important if they tell you in the procedure

A- DO it to the letter?
B- Try to do it best you can?
C- just drive down the road, hits the brakes a couple of hard times and DONE?
D- none of the above


and does the BMW place follow it to the letter

the key is not to over heat them before they cool. i've always gone to 30mph and do a slow stop and drive for 1/4 mile to cool them and continue the proces,, it depends on if you turned or burnished the rotors to give the pad something to find.
generally most people just drive them thru the city and that works
you can always go to a pad supplier web site; ie wagner or others

Option A, always, unless traffic gets in the way and forces option B. I live in mixed farm/suburban country so dark, empty back roads are my post-wrenching test-drive routes of choice. It's usually not a problem to run the 8-12 stop, 20-minute cycle late in the evening. The last few stops from freeway speeds are tough if there is any traffic on the nearest highway. (The local constabulary might overlook 40-45 on a 35mph country road...but not 60+.)

I am especially careful to follow procedures to the letter when switching from street to track pads and back without changing rotors. Braking feel and performance is miserable until the pad and rotor profiles are matched again.

I try to follow to the letter. I have a nice road that's got little traffic that I use for the highway speeds. My wife wanted to come along once when I did it... Didn't explain what was entailed... That was fun.

Follow manufacturers recommendations. Procedures are different for semi-metallic, carbon-metallic, carbon-Kevlar, ceramic, etc.

For such little effort exerted, you'll get the best possible performance.

From what I've read, it seems to be important to let the brakes cool down completely after bedding them in with a few vigorous stops.

I usually finish in the evening, bed the pads, then leave the car overnight.

I put new zimmerman rotors on, the pads had less than 1000 miles but still they seem to be performing great

Depending on the procedure, the brakes can get hot enough to smoke profusely.

Obviously, if they're this hot, keep rolling and cool them down (airflow over rotor during easy driving) before stopping.

I did Zimmerman rotors too. What pads did you pair up with them?
