Bedding new rotors and pads

[petrv]

I finally got my new ATE blank rotors and Ferodo DS2500 pads, I will install it on weekend.

I've read two bedding methods:

1) Should I put both new rotors and pads and bed them in together?

or

2) Should I first put new pads with the old rotors and bed the pads, then put new rotors with the new "bedded" pads and bed the new rotors separatelly?

What do you think?

you should do them at the same time.
just go easy on them for the first hundred miles.
around town and moderate braking should break them in nicely
just no hard braking at highway speed.

make sure you change the shims, clean the crap off the caliper mounting bracket with brake cleaner (where the pads sit), and lube everything up with the caliper lube to prevent noise.

dont put lube on any friction surface

yeah, just do what boom said. when i replaced my rotors and pads, it said to take it easy for the first 200-300 miles. no hard braking at all, but you should be good after that.

bed them at the same time, or at separately, most people don't have any convincing evidence either way, unless you're using a funky compound that may react with the cementite and other build up on the old rotors.

bed the SHIT out of them, meaning, get em nearly smoking, but not quite. the method i got from cobalt-friction is:

5 medium hard stops from 50 m/h to 10 m/h

10 minutes cooling

5 hard stops from 50 m/h to 10 m/h

cool overnight.

do not come to a full stop with the new pads as they may glaze if you do. it's best done in an unregulated, open space, or late at night on empty roads with few signals.
