Is this a good idea? Sounds a little crazy but hear me out. I've done a lot of reading about the need to bed in brakes and the need to get the rotors progressively hot. Couldn't we mimic this on the freeway? What I'm thinking of doing is essentially riding the brakes to get them hot without slowing down for 4 seconds then release brakes and do it 25-30 times for the ferodo ds 2500....?

I used empty back roads late at night so there was minimal traffic. I would think your idea would work just gotta make sure you dont hold them for too long to start with so you don't overheat them.

I couldn't "torque" the pads without slowing down too much as I want to hit 80 then drop down to 60... Would heat still bed the pads with minimal torque?

Yea it would work... but i feel like your working the engine/turbo and clutch especially, too hard to do it that way. plus... my gut feeling, have you ever brake boosted... that **** sounds like the engine is gonna explode.

but i dont really know. id be curious to hear an actual knowledgeable answer. either way im gonna stick to the freeway method

I'm sure there is an industrial park you can drive to where you can bed in your pads without attracting any attention.

Heat alone will not bed in the pads, you need to use them - bed them into the rotors - overheating them will cause them to glaze = poor braking power. You wont get the rears bed in with that idea, you wont be using the rear brakes hard enough.

^^ makes sense

I'm mainly concern about doing it 25-30 times.

How many sets of pads do you have?



All you need to do to properly bed in your new pads and rotors:

1. 5 light snubs*, light pedal application: 50mph – 30mph
2. 5 medium snubs, medium pedal application: 70mph – 40mph
3. 3 hard snubs, hard pedal application (no ABS activation): 100+mph – 30mph**
4. Cool down period – 5 mile run with very little brake (Do not sit at side of road with foot resting on brakes when hot, this is likely to damage the disc).
5. Stop and examine discs – discs should show evidence of heat cycle (colouration in flange) and possess an even transfer layer of pad material on surfaces.
6. Bedding procedure should now be complete.

* Snub is the term used for the deceleration of a vehicle from a relatively high speed to a low speed using constant brake pedal effort.

** The location as to where the brakes are bedded is at the driver’s own discretion and entirely his/her own responsibility.

That's what ferodo have on their instruction manual... 25-30 times of half of race condition brake pressure... It does seem a lot more than what other companys are saying which is 10 times and progressively as you mentioned.

I use this on all the pads I run:

^ This.

Wouldn't the harder compound need additional bedding since it takes more to heat up? Which is why ferodo requires 25-30 times or am I wrong in thinking that way?

DS2500 has a working temp from 100-1000F. It's not the hardness of the compound you're trying to effect. It's the application of a fine film to the rotor and final burnishing of the pad compound (baking).

Let's put it this way, if the pad is not in the 100-100F range within the bedding procedure that I prescribe to then its not one that should be used on the street. (Race pads don't need that much abuse either. IMO Ferodo went overboard on their bedding).
