I have read a few posts from members that they installed crossdrilled rotors,and bedding-in there brakes.Thats going from 60mph-10mph 6-8 times close to abs territory.Bedding brakes are suppose to make your brakes last longer,keep your rotors from cracking and keep the squeal down.I have a couple of questions.Did you bed in your stock brake?I have 2k on my Jeep is it to late to try bedding them in?Maybe bedding in the stock brakes will help on that squeal eveyone has,and the grooving rotors.Its funny all the cars I had and all the brake pads I changed in my life I never did this procedure,and it makes perfect sence.To anyone who doesnt know how here is the link.Kevin...http://www.zeckhausen.com/bedding_in_brakes.htm

I bed all new brakes.

I don't think it's too late, although at 2000 miles your pads may have already set. It can't hurt to try though.

I was going to ask this same question. So I have 11K miles, too late to do right?

I was going to ask this same question. So I have 11K miles, too late to do right?It's never too late. When I buy a new car, I wait until the motor is broken in, then I bed in the brakes. It's amazing how much stronger the brakes can feel after they've been bedded (and cooled off) for the first time. Simply being an aggressive driver will not result in properly bedded brakes. You really have to follow these instructions: Bedding in Brakes (http://www.zeckhausen.com/bedding_in_brakes.htm)

When the Nissan 350Z was not quite out, I drove a pre-production model that had been used by various magazines for reviews. (We were performing baseline brake performance testing as part of the development of a big brake upgrade.) Those press guys did not go out for lazy Sunday drives! Yet the brakes still didn't feel very strong. After bedding them, they felt much better. It really works.

Here's a white paper that explains some of the physics behind bedding: Bed-in Theory (http://www.stoptech.com/tech_info/wp_bedintheory.shtml)

With Dave's pads on the drilled and slotted rotors, yesterday with 100+ quarter mile, passes my brakes feel terrific. Blackstallion made a couple of passes at the end of the day in my ride and loved the feel of the brakes.

Very satisfied, although they are low dust pads, my wheels look like hell after that much high speed use. LOL

Quick hi-jack. Talked with Dave and ordered Centrics Mon. Arrived in Valrico fl. yesterday. Thanks for your help on the phone and the outstanding service and delivery time, Dave. It is not hard to understand why you have such an excellent rep on this and many other forums, for having "true" knowledge and providing excellent service. Putting them on this coming week. Read the bedding in process and white paper. Looking forward to the install. Ted

Dave - Thanks for the info. So I did the bedding process yesterday morning on my stock Jeep SRT8 with OEM brakes with 11K miles. I was out and about early and thought I picked a good time, but only got 5 passes in before cars just flowed out of no where. What do you suggest as my next step? Do it again? When? By the way, it's only been 1 day but my squeal is about half as loud. I don't want to get excited yet. Also, the stopping power of the brakes, after the partial bedding, feels about the same. Thanks in advance.

Thanks in advance.I would do it again. If you don't do enough passes to get the brakes hot enough to start the pad transfer process, it's as if you didn't do anything at all. So you'll be starting from scratch next time you do it.

There's a really nice road a couple miles away, where I regularly bed in brakes without interference from traffic. Before finding that road, I was incredibly frustrated by how many other cars always seemed to be right there at the wrong time. At least you've got a powerful vehicle and can rip off 8 to 10 quick braking events from 60mph in a short time. Imagine if you had a BMW X5 with the base 3.0 liter inline 6 engine. :eek:

I bedded my stock brakes the other day,I found a strip where to do it safely plus you need room for the cool down,I tell ya, it took alot before I started to notice brake fade, I went from 60 sometimes 70 mph down to 10mph 9 times I think 8 would have done it,then I drove it about 15 min cruising at 50 mph to cool down,I got out to look at the brakes and the rotors have a slight blued look to it but the caliper was slightly warm to the touch already (amazing),If that was my Denali the brakes would have been on fire!Well so far so good the brakeing feels close to the same, but my squeals are gone,Everyday in the morning might right rear always squealed,see how long it lasts.Kevin...

The factory SRT8 brake pads (manufactured by Jurid) are unusually abrasive when cold. So, I expect it won't be too long before they unbed the rotors and you start to hear some squealing from the rear calipers again.

I bedded my Centric pads this past Saturday. It was pretty fun and didn't take long at all. The brakes started to fade and you could really smell them. Also got the blue tint on the rotors. So far, I like the pads, not quite as much grab at first but it definitely stops. Definitely will not miss the brake dust from the stockers. I am getting a slight noise from the pass. side rear though. Hopefully it will go away after I get some miles on them.

If so, it will go away after some more miles. If it is still there in two weeks, repeat the bedding process and that should take care of it.

I will go with the centric pads as well, my stock ones seem to be fine right now when they start acting up is when I will change them.No smell from the stock pads after 9 hard stops:confused: Kevin...

Thanks for the good news:( I did notice they made more noise on very cold days ,and it did warm up around here so we'll see.Thanks for all the advice Kevin...

Yes. I thought I read something about this somewhere else. Thanks for the info.
