Re: WK2 SRT Brembo brake kit on an Overland

Scott, I am not wrong, you need to ask an engineer that deals the the actual physics, not using a bum-o-meter and a misconception. I am not doubting your "feeling" that it was a shorter distance, but unless you can provide scientific FACT, your testing is flawed.
The only "fact" you are using to gain your viewpoint is your test. You have failed to interpret the information that I an the others have provided. I am not going to argue with you on this forum, as I know I am right, and you believe that you are right.
Getting the truth from an engineer will tell us both who is right.

Re: WK2 SRT Brembo brake kit on an Overland

it was almost 5 yrs ago now...but I posted the same things on the other forum. The jeep stopped like 20 ft shorter with the brembo brakes. Its not a "feeling"....its a fact as I know it. I did NOT use a "Bum-o-meter" or misconception! I took actual measurements. I could care less what anengineer tells me about a "theory" that they have never tested. Theories are proved wrong everyday. Im just posting my "actual" test results...not somethig I read on wiki or the net.

Re: WK2 SRT Brembo brake kit on an Overland

I guess you must be right then, as you would not want facts to get in the way of your actual measurements. We will just agree to disagree.

1. your test was hardly scientific, how about try reading the C/D test which is a little more controlled. the BBK stops FURTHER than stock. you know why? BBK's were meant to reduce fade created by excess heat, therefore pads that typically come with BBK's are more race oriented and therefore do not perform as well under operating temperatures, but they'll perform like the dickens at 300F

2. the theory is sound if you know anything of physics/thermodynamics, and has been tested over and over again by scientists and drivers alike

3. the theory and FACTS of braking are quite old and proven, your story of a time 5 years ago does not disprove physics. if it does, you should be up for a nobel prize in physics shortly, but be careful travelling to Europe to collect, you might fall off the end of the world once you hit the horizon

4. Enforcer and I seem to actually know our shit, and the amount of knowledge we are bestowing on this thread doesn't come from a wiki, i challenge you to find a wiki summarizing the FACTS that we've summarized for you. It comes from a grasp of physics and actual racing experience. Again, a singular unscientific test without repetition and controls means nothing.

I know its hard to swallow the fact that people spend thousands of dollars on braking systems they know nothing about. But its better late than never to actually understand what's going on. Tires, pads/lines/fluid, rotors, BBK really ought to be the pathway to better braking.

AND FOR THE LAST FREAKING TIME... BBK DOES NOTHING TO SHORTEN THE FIRST FEW STOPS!!! IT ACTUALLY LENGTHENS IT!!! BBK's ONLY TRUE POINT IS TO REDUCE FADE INDUCED BY REPETITIVE HARD BRAKING (or for the bling factor - if that's your cup of tea)

Re: WK2 SRT Brembo brake kit on an Overland

frydryce,

Any particular pads?

You mean braided brake lines, right?

Any particular brake fluid?

Also, just to understand some things... why those Limited and Summit V8s then come with bigger brakes or Heavy Duty brakes?

They have a higher tow rating. More weight being towed = more heat = bigger brakes

Re: WK2 SRT Brembo brake kit on an Overland

Thanks Enforcer,

Makes a lot of sense having more weight requires better braking performance.

But you know, besides the "feeling" part of this other post (belongs to the "brake rotor sizes" thread) , I can't understand why Laredo’s didn’t come with HD brakes even in their V8 version, with towing package, like the guy explained there.

For me it has some logic to have better equipment (and that could apply to brakes as well) as you move upwards (Laredo, Overland... & SRT8?). But then, for a reason, all things explained here seems to apply to any vehicle (no braking distance improvement whatsoever by changing your rotors to bigger ones or to Brembo kit). On my case, this is... to have the HD brakes or Brembo with bigger rotors on my Laredo will not improve my braking distances.

Going back to my first post here (Braking distance comparison between WK2 and other SUVs)… taking into consideration weight, and what you guys explained (both "sides" ;-) )... and taking into consideration what the guy experienced by having a WK2 Laredo as well as a WK2 Limited for a head to head comparison (something few of us have)... I can speculate then that may be the factory brakes aren't enough for Laredos, given the WK2 platform weight.... and on my case, even more weight (20" wheels)

By the way, in the PDF with the brake rotors + pads comparison, I understand it applies to that single tested car (unknown)... and I presume brake system for that car was an optimal / best design from the factory.

upgrading pads comes with a whole other discussion and fight! haha. Honestly I don't have much to say about domestic application pads since I have exclusively used Endless pads (japanese) on my other car and have not done much research about upgrading my jeep's pads. however i have heard many good things about porterfield and hawk pads. both are reputable companies that will give you an increased bite feel as well as better fade resistance at the expense of increased brake dust

regarding your question about v8 laredo versus limited/overland i'm not sure why. i had just assumed that the v8's all had HD brakes. the reason they have bigger brakes is they are expected to tow more and therefore need more surface area and performance to continually stop 10,000lbs going through a downhill pass without catching on fire. why the laredo v8 is not expected to tow as much i'm not sure (i'm saying all this without having gone to the jeep site and verifying info - if i'm wrong, feel free to correct me on tow rating and specs)

Re: WK2 SRT Brembo brake kit on an Overland

Thanks frydryce! no, no more fights!

Truly, I just want to decrease my braking distance. So far the only common or accepted fact by all is to upgrade my factory tires to ones with better traction.

I am somewhat reluctant to believe that besides upgrading our tires we can't do anything else. So I am going to look at those pads, braided lines and, well... keep searching more info.

Will upgrading brake fluid helps to decrease my braking distance? What I know is important is the boiling point, but I think its importance is for very high heat scenarios, like race cars.

As delivered from the manufacturer, nearly all modern cars are able to engage the ABS or lock the wheels at the speeds stopping distance is generally tested (e.g., 60 miles per hour). For this reason, the test primarily measures the tires' grip on the pavement. Therefore, an increase in braking power will do nothing to stop the vehicle in a shorter distance. However, braking power becomes more important during extended or repeated braking, or braking from higher than normal speeds or under higher than normal loads. While it's true that the tires are the most important factor in determining stopping distances on modern cars under normal driving conditions, Rose City GC SRT8 is right that they're not the only important factor.

I love a good discussion!

unfortunately for single stopping distance yes, tires are your only way out. for multiple stops and to prevent fading, then all upgrades will help. The only other thing you can do is reducing your intertia - lower your speed and/or decreasing your weight
