Vibrations when braking

No new car manufacturer recommends or does “bed in’s” on new cars. If that was the case every factory would need a bedding in facility. I have spent a ton of time at the Toyota plant in Fremont California and I can tell you they do not have a bunch of people running around slamming on the brakes on new cars.

I have done at least 200 brake jobs and I have never bed in a job. With the exception of a couple jobs where the owner used junk parts I have never had one come back. I drive the car up to highway speed and check for vibration and squeak, that’s it.

Rant off, sorry

The solution is to replace the pads and rotors with OEM Jurid in the front and Textar in the rear. .....

I have to disagree here. I have done a lot of brake jobs as well, and I have found that bedding in is an important step. The degree to which it is required varies quite a bit with pad composition and rotor surface finish, but I consider it part of the brake job.

My experience with the Axxis Deluxe pads was that they required bedding in more so than many other pads, but that once it was done the pedal feel was equal to the OEM pads. That may have varied with my specific new rotors, as well, as that is the other half of the equation for the deposition of pad material on to the rotor surface.

Jurid is owned by Bendix. Bendix does recommend bedding in new pads, sometimes more stridently than other times. It depends entirely on the pad material. Bendix has also promoted new pad designs that include a metal strip on the pad surface, designed soley to reduce the bedding in time (their words).

Too many brake pad manufacturers (and the SAE) talk about the initial transfer of pad material to the rotor surface for me to discount it as a myth. I do think that it varies so much with pad composition that it is more of an issue with some pads than others. If I was a manufacturer I would specify a pad with less requirement in this regard, soley to reduce warranty claims for noisy brakes.
