I don't think I've ever seen this question before, but I'm putting in some fresh pads and rotors today and it's wet outside.


Do you think moisture can effect the bedding in process?

I'm thinking no... But I wanted to ask before I go possibly ruining my $$$$$ brakes. :)

I'll post pics of the rotors... if they ever get here.

But I have to go wish my neighbor a happy birthday... it's free dinner. :)

Well... the rotors need a bed in as well as the pad.

Since these aren't a full "race" pad, I'm going to do a simple 60-30 hard brake, then cruise for 1/2 mile... then repeat about 6 times till you begin to feel the brake fade.

Then repeat as necessary. Stop-tech has a good article on this procedure.

That's what I'm running.

My only complaints are they started to squeek at low speeds the other day, probably gonna rip them apart and see if I can find what's causing it. And my white wheels don't like the dust too much.

I bed mine in "by the book" and still had problems. I installed new rotors, pads, calipers, toyota clips...lubricated and torqued properly.

- brought up to temp by several slow stops (but without actually stopping)
- did about 7 hard 70km/h to 5km/h stops
-drove for 15 minutes without touching the brakes

seemed to get an even spreading of pad on the rotors and worked great....it later developed a vibration in the in the pedal and wheel. I assume it's due to breaking them in too hard and getting uneven distribution, the rotors will most likely have to be ground.

stop tech says they've never actually seen warped rotors, only inconsistent pad material on the rotor.


I figure there are 10s of thousands of cars on the road that have new brake jobs that haven't been "bed" in and are working fine. I won't be doing it again once I have my rotors reground.

Not Supra but I thought step #4 was pretty hardcore!
06 dodge charger police package break in procedure.


CAUTION: A burnish procedure must be performed when new brake pads are
installed. This procedure is particularly important in situations where
high speed pursuit is a possibility. It is recommended that the procedure
be performed by the Police agency operating the vehicle so it can be
performed in a safe controlled environment. This information is also
covered in the Police Package Owners Manual Supplement which was
supplied when the vehicle was originally delivered.
1. Perform a series of moderate braking stops by first accelerating the vehicle to 55mph,
(88 kph) and maintain speed for a few seconds.
2. Apply moderate braking pressure without coming to a complete stop.
3. When 5 - 10 mph (8 - 16 kph) has been reached, begin accelerating back to 55 mph,
(88 kph).
4. Repeat sequence 40 times allowing 30 seconds between braking to allow brakes to
cool.
5. When procedure is complete, allow the brakes to cool completely before driving again.

I usually do as many 60mph-15mph stops as I can get in before brake fade occurs. Its usually between 2 and 5. Autozone pads on stock rotors barely make 2, slotted rotora discs and hawk pads took up to 5, but there was a 90mph blast in there as well :p
