I had a crazy thought, Ideas please.

[8v-of-fury]

I was looking at solid rotors earlier on a website.. and saw their cross drilled rotors at 4X the price..

Can i take some solid rotors.. mark them up with the drill holes and drill it out on a Drill Press?

I can't see why this wouldn't work as a poor mans X-drilled rotors..

what are your thoughts?? 

[Turbinepowered]

I have a feeling that the poor man's version would shred pads, unless you wanted to countersink and deburr the edges once you'd drilled.

Then too most of those are cast with the dimples and holes in them, making them stronger than a pre-cast then drilled part, less likely to crack under the heat stress.

[mystery3]

Not to mention warp, crack or shatter!

Not a good idea. If you feel you need drilled or vented rotors it would be best to buy them that way from a reputable manufacturer.

[theman53]

IF your rotors are unturnable then this would be the time to experiment....As little highway as possible of course.

[rabbitman]

This would work better i think http://www.partsgeek.com/catalog/1984/volkswagen/scirocco/brake/brake_rotor.html

They're for a scirocco but the size is still 239X20mm (solid is 12mm)

You'd have to also get GTI pads since they're thinner.

the x-drilled rotors are probably made from higher strength steel to cope with heat stresses...

i'm going to throw out an idea i've been having for a while now though, that will destroy brake systems and give light to the future. electromagnet brakes! oh yesss!!! instead of having a caliper, you have two circular stators that bolt to eachother and then bolt into the existing holes for the caliper mount. the stators have coils all around in an equal fashion. the new rotors will have permanent magnets embedded as well. this gives them the ability to produce electricity

just think... the 'poor' (if someone can build this system cheap) man's 4 wheel drive  . the front wheels turning produce energy to power the rear wheels. for braking, no more brake fluid, bleeding, and brake pads n warped/worn rotors. a simple PWM is used to 'pulse' the front brakes from the rear brakes as a certain ratio to keep the back end from breaking loose. essentially a 1.5:1 ratio front:back or something close. best part about this, is that for braking purposes, the system can be completely independant of the electrical system so it would be much more reliable (the front brakes power the rear brakes, and rear brakes power the front brakes and the pulse width modifier controls the force of the braking power) best part about that, is traction control can be easily implemented, and probably the most efficient ABS ever  . as for heat, all ferrous metal from the brake system must be eliminated. ferrous metal is the worst for creating heat from resistance. with a ferrous rotor, i could see some bad things happening under extreme braking... i was thinking of using a high strength epoxy.

how's that for an idea? a little over budget though huh 

but honestly, i wouldn't even worry about the rotors on these cars. i've never had my rotors warped... but i know GM and domestic cars have warped/crappy rotors all the time. i think the solid rotor config is the best... now as for those 'slotted' rotors, i think they're an ok idea. good way to get rid of brake dust and give better grip! however, you'd need a special lathe to do those, so it would be cheaper to wait for canadian tire to have those nascar ones on sale

What about ebraking? That'd be terrible to yank the ebrake and......wait it would have to be an electric ebrake too.
Well I like to slide so the ebrake would have to lock without effecting the front braking. And the antilocks would need to be switchable since it's fun to lock all four sometimes.

Yeah thos drilled and slotted rotors look cool but I've never had a problem with the solid ones getting too hot.

i've thought about the e-brake and parking brake, and you're right about the e-braking... either way energy would be required to power the rear tires, either from the front wheel movement, or a capacitor bank or battery input. theres another way to extact energy from the rotation of that same tire, but i'm not sure if it would react fast enough...

Magnetic Brakes Demo

thats an idea about using an aluminum rotor

[macka]

brake material is generally treated to the same specs regardless if they are slotted or not. They are specc'ed to heat up up but not work or heat harden past their manufactured hardness.

so I could theoretically drill them with lube as to not change there tensile strength and round them out as to not chew pads and it should work fine?? I could experiment on older rotors anyway lol

[maxfax]

This may actually work okay with the solid rotors, dunno if I woudl try it with vented ones though.. Drill them with lube, and maybe slightly counterdrill them to eliminate any rough edges, and let us know how it works!

[neimis]

Do you really need drilled rotors, or is it just for fun? Reason I ask, is that I changed over my solid front rotors to the vented rotors, and didn't notice a whit of difference. Nothing. For normal street driving, anyway.

So if it's for fun, by all means try it, but I'll be very surprised if it makes any noticeable difference in braking performance. If you decide to go ahead, let us know how it turns out.

[Smokey Eddy]

in response to jtanguay's video,
That braking system could be instantaneous...
you could use electro magnets. give them a charge at the blink of an eye and boom full braking force. It is the exactly opposite of an electric motor.
if you spin a lathe backwards or a drill backwards you are putting power back into the wall
i believe the prius has dynamo brakes. It is not new technology.

[catlin_cava]

Jeremy I should got to ontario and beat you for having such an Idea of drilling your brakes

[8v-of-fury]

Purely for fun. lol My car stops very quickly over and over again on the pewny solid rotors it utilizes. Dunno what the super fuss is about bigger vented and cross drilled brakes.. oh wait yes i do.. its for the people that make the car so fast they have to be able to stop before they hit the minivan in front of them lol!

I'll probably try it out, i was just checking to make sure  that the heat of drilling would create enough heat in one spot to crack or shatter... but i have had my brakes fail before.. and i managed a 50km drive home  thank god for back roads lol. So i got that covered lol.. and of course i will carry my good rotors in the trunk during this experiment lol.
