rotor question

[sloth69mustang]

so crossed and drilled rotors.... is that bad for off roading? idk if the holes get filled with mud or what. idk i havent been sleeping much this week so my brain isnt working at all the last couple days. but i would assume its ok. i am ordering up my last couple pieces to finish my 8.8 project

could be wrong im still not fully awake.. but i would think that the spinning would spin the stuff out?

The purpose of drilled rotors and whatnot is for faster cooling. Required pretty much for high speed racing where brakes are used hard enough to get them rather hot.


I can't see how this would affect use in offroading.

 

[sloth69mustang]

it affects big tires. it takes a lot more work to stop a 35" tire than a 28" tire. and i know how they work. i just wasnt sure if there was some reason why mud would be bad for them.

and smokeater you would think? but idk its a little dif than a wheel. since it is so close to the center of the wheel it may not have enough spinning force to knock the mud out? idk

Running the two piston brakes I've never gotten my brakes anywhere
near hot enough to consider needing crossdrilled rotors.

With the old single pistons brakes? yeah, all the time, but that wasn't because the rotors were "inadequate" it was because of the caliper design and wear of the steering knuckle the brakes never completely released so they were dragging all the time and that put an awful lot of heat into them that had NOTHING to do with stopping the truck.

So, if I'm interpreting that correctly he is saying run dual caliper pistons and stock rotors which should result in a lower investment over time with the same desired braking effects as the drilled rotor.

I think to put cross drilled disc does not really performance brake we have not racing car, its vehicle for the mud.after your off-road clean them simply , his car not need winch

i just was trying to prepare for 36" tires and the force that would be put on the stock calipers. its for the 8.8 so those rears are single piston but the rear brakes only do 30% of your braking anyway. i just wasnt sure if anyone else really used them

Check out the Brake Bible here:

i would say about 1/2 way down it has a section on rotors, and it goes into some detail, and i tend to believe the article.

good info for the average person. but i knew that already

i guess what i need to know is if my theory is right with having bigger tires there is more force on the brakes? if so it i would want a better preforming rotor.

 

[sloth69mustang]

oh i guess i forgot to mention that my truck is a daily driver. if this was just a trail rig i wouldnt think twice about it and i would put solid rotors on it. but since i will be ripping 80+ mph and be hitting the brakes that is a lot of force to stop.

 

[Nhaz]

just remember. Its Not the brakes that stop the truck. Its the tires.

So Unplug the abs and if you can lock up the tires without any trouble then you have enough brakes.

Don't forget to plug the abs back in.

Cross drilled rotors aren't bad as long as you don't mind swapping out rotors all the time.

The variations in the rotor result in warping.

It's no big deal on race cars, since they swap them out after every race.

Go with the cross drilled and slotted, thats what I'm running on my rig, and I definitely noticed a difference, both on and off road. They do clog up with mud, and sometimes can be cleaned with a hose or pressure washer after a run, a coat hanger or small welding rod can help for the stubborn ones. I have had my rotors on for about 2 years now, and have gone through 1 set of pads and about half way through my second set, not really any problems, the outside edge does show small heat cracks, but only the outside, the inside the rotor is still solid, hope this helps

finallyyyyyyyyyy someone gives me an answer i was looking for. everyone else was trying to get me brakes 101 and i am ase certified and knew all that info. i just needed to know if cross and drilled were worth it for off roading/daily driver. sweet now i can order them lol. thanks for the help guys.
