? new brakes and rotors "bedding"

[mmarsden]

have new rotors and frt pads on the bike and was wondering how the hell to "bed" them.. can it be done at the track? i dont want to screw anything up. i ahve been told get bike to like 55-60 put on brakes hard then get back up to 55-60 repeat 10x then release and continue driving with brakes off ?? is this right?

What PADs/Rotors........I know EBC has there Bed-in procedure on the back of the box the pads come in...

[mmarsden]

brembo snowflake and dp pads?

[OreoGaborio]

Ride around dragging the brakes for a few minutes. Don't overheat em & don't come to a full stop hard on the brakes.

I used to essentially do a quick 20-5mph, 30-5mph, 40-5mph and go.

This is from EBC but gives you and Idea.... I just go easy for a few laps lay off them and then go hard and keep an eye on them from there for a few sessions....

To bed in brakes with new rotors, undertake this in a practice session and allow 20 medium speed "snubs" at 10 second intervals scrubbing off speed from 90 MPH to 60 MPH followed by 10 snubs taking speed from 110 MPH to 60 MPH again with 10 second intervals. This will avoid rotor pick up. If rotors are pre -conditioned against sintered pads and perfectly flat, bed in time for PADS ONLY can normally be achieved within two warm up laps with 7-10 snubs from 110 MPH to 60 MPH. Bed in time depends on rotor condition, allow longer bed in for even slightest dishing of rotors. If you have previously used carbon based pads you MUST Scratchpad or sand rotors lightly to remove carbon coating.

thx-

interesting.. i never knew brake rotors required a break in period and procedure... I feel like Im learning all over again with Street machines after learning cars to some extent.

You never bed in the brakes on your cars?

[Paul_E_D]

Pete! Don't suggest the dragging the brakes around technique...EVER! I know too many people who have faceplanted doing that. Some rotor/pad combos will "come in" instantly, leaving the rider little to no chance at saving a lock up. It also begs to be done without gear on when speeds are low. We all know how that ends.

The EBC procedure is the ticket, though it can be done at lower speeds. 60 mph is good enough.

Nope... I was never taught anything about it that I can remember in my Vocational school... "cut the rotors, put a non-directional finish on them and put them back together with new pads." Learn something new every day!

BVT short changed you :p Bed in on brake pads in cars same as bikes. The exact numbers varies depending on manf. of the pad and pad type.

Now, that's if you put new pads in. But what about rotor seasoning? I've always wondered if it's bad to bed in brand new pads on brand new rotors before they have been seasoned. I haven't had any problems, but is it worth worrying about?

And wouldn't simply dragging the pads not build heat, but just glaze them?

[Paul_E_D]

No, dragging the pads works, it's just that sometimes when the material gets up to temp it goes from no friction to MAX friction in less than a second. We know a guy who tore his face off this way... I have nearly crashed doing it, and know quite a few people who have. It's funny to banter about, but stupid to do.

I locked my front brakes dragging them and the front tire screeched and smoked causing the bars to jerk to one side but fortunately I recovered and didn't dump it. Last time I'll do that.

Hahaha... Yep, BVT baby... I just haven't really seen any effects on cars anyway... but I would think that just using the brakes normally would be all the "Bedding in" you need.

But what the hell do I know? Brakes are brakes. The pads clamp the rotors and turn kinetic energy into heat energy. The more efficiently you can do that the more powerful the brakes will be. I would do a couple hard stops on a bike just to seat everything and call it a day. Regardless of new pad/ rotor combo. Thats just my opinion.

Believe me. I can speak for cars only, proper bed in even aftr the fact can Improve pedal feel a ton.

whats your preferred method?

[aldend123]

whats your preferred method?

Just the standard recommendation. High speed to low speed (usually I do 70 to 20) hard as possible braking, and repeat ~8 times. I believe larger brakes, and ceramics are going to need more stops and/or higher speeds to build the heat. If you've never done something like this before, do not forget that once you reach end of the series, you're brakes are going to suck the big one. And you want to have room to coast to cool down without having to use the brakes. Need plenty of space.

[mmarsden]

how long should you coast without the brakes to cool them down

[mmarsden]

is this all possible on the track or is it hard to do on the track

[hondarocks61]

hehe. I wonder if this has ever been used as an excuse for speeding

[aldend123]

how long should you coast without the brakes to cool them down

That's a good question. On the street, since this is usually performed on the highway, most people are going to just drive for a few miles. But I'm willing to bet you don't need to drive that long.

Also, I mentioned ceramics, but now that I think about it, I probably shouldn't have. Because the materials are significantly different, and I don't know what the procedure, if any, would be.

Curious, for those who drag, how long are you dragging? And how do people who race handle this? Or are the brakes bedded by the first heavy braking turn?

[OreoGaborio]

I think that's been answered by a few racers in this thread already.

Most of us ride around the pits at safe speeds and make a few relatively hard "stops" (but don't come to a complete stop). Some of us ride around dragging the brakes a little, but we're careful not to overheat them. (Happy, Paul? )

Personally, I brake hard from 30 or 40mph down to ~5mph bout 3-5 times with a little of riding in between to let them cool a little bit.

sounds like a warm up lap

[OreoGaborio]

Pretty much. I do a little riding in the pit area before, just to make sure.

[Paul_E_D]

Agreed, the track is ideal for this. One short practice session and you're done.

Going out to race straight away could be bad, cause the rotors run pretty hot in race conditions. Prolly be fine, but could glaze.
