Trust me, after the swans got out of the superblue, you didn't want them anyway ;)

I know I ask this alot, BUT, is this something I could do? I'm sure it would require bleeding the break system since you are replacing the lines. Also, what are "swans"? :D

I was half tempted at this, but I've put maybe 15K on the brakes you guys did and really, I only want the SS brake lines just to say I have SS brake lines.  I could always save the pads though.

What's left for Christmas specials???? :)

I could not pass up on this GREAT brake upgrade deal!!! New "J" Hook Rotors and HPS Hawk Pads with steel brake lines (already installed). I am looking forward to putting the car up on jack-stands in the wonderful New England winter and doing this. I think I will wait until it actually snows, that way all my neighbors will think that I am totally crazy and have "lost it".

Thank you DDM Works!!! You guys are the best!!!

Just received my rotors and pads. Now to find a garage to do a little brake work over the next weekend. I am glad the weather will be nice, hopefully come next Monday afternoon, I will be all done.

I will post updates after I get everything done with the new "J" Hook rotors and the feel/power for stopping.

My biggest worry is finding a long enough stretch of road to properly seat the brakes and pads before the first snow of the season drops on New England.

Any DATA besides discussions?
My understanding is the drilled rotors are to dissipate heat and slotted rotors are to clear water from the surface.
Don't see any improvement that the extra hook can do besides trapping water at the center of the rotor and being so ugly...  :2c:

Data is out there.   

First up, It's stronger and cheaper than a lot of OEM rotors.  Not sure with our rotors as I have a Wilwood Conversion on all 4 corners with larger rotors. 

Drilled rotors are for weight.  They have less metal and therefore do not dissipate heat as well.  Drilling also weakens the rotor.  Cracking can occur in a connect the dots fashion under high heat

Slotted rotors scrape the surface of the pads every pass and remove stuff from the surface of the  brake pad specifically glazing which can occur on crappier pads but normally isn't an issue with good pads.  It's amazing how much better my slotted rotors are in the rain compared to the stock rotors on our cars.

Both help dissipate gases that generate under braking

The hooks act like a combo of both without the weakening of the rotor like a drilled rotor.

It's a neat idea and has been proven to be both durable at high heat use and resist fade under track circumstances.

Thank you for your input as to the j hook type rotors...
I must correct you in one of your statements on drill rotors. You say that the drilling in a rotor is to reduce weight, Not so, its for dispensing heat, gases and water nothing to do with weight... Again, thanks!

I'm going to disagree with your disagreeing and the brake experts agree with me
I will agree with the wiping effect, but......

Quote from: Wilwood
Rotors are drilled to reduce rotating weight, an issue near and dear to racers searching for ways to minimize unsprung weight. Drilling diminishes a rotor's durability and cooling capacity."

Quote from: Grassroots Motorsports
"Crossdrilling your rotors might look neat, but what is it really doing for you? Well, unless your car is using brake pads from the '40s and 50s, not a whole lot. Rotors were first drilled because early brake pad materials gave off gasses when heated to racing temperatures, a process known as "gassing out." ...It was an effective solution, but today's friction materials do not exhibit the some gassing out phenomenon as the early pads. Contrary to popular belief, they don't lower temperatures. (In fact, by removing weight from the rotor, they can actually cause
temperatures to increase a little.) These holes create stress risers that allow the rotor to crack sooner, and make a mess of brake pads--sort of like a cheese grater rubbing against them at every stop. Want more evidence? Look at NASCAR or F1. You would think that if drilling holes in the rotor was the hot ticket, these teams would be doing it...Slotting rotors, on the other hand, might be a consideration if your sanctioning body allows for it. Cutting thin slots across the face of the rotor can actually help to clean
the face of the brake pads over time, helping to reduce the glazing often found during high-speed use which can lower the coefficient of friction. While there may still be a small concern over creating stress risers in the face of the rotor, if the slots are shallow and cut properly, the trade-off appears to be worth the risk. (Have you looked at a NASCAR rotor lately?)

Quote from: Darrick Dong; Director of Motorsports at Performance Friction
"Anyone that
tells you that drilling makes the disc run cooler is smoking crack."

I'm with Elff. Always heard that drilling was for weight, slots for cleaning. Of the two, slotted rotors are difinitely the smarter choice for racing. I suppose the idea with the driller rotors is that the holes increase the surface area, and therefore the amount of metal that's in contact with the air, but the loss in mass makes up for that from what I've heard.

Wasn't there a big talk about racing brakes where the brake ducts force air through the inner cooling fins of the rotor? Something tells me that wouldn't work too well if the rotors were drilled through...

From:Howstuffworks.com
Having drilled holes on a brake rotor makes it easy for heat, gas and water to be quickly moved away from the rotor surface, keeping the brake performance strong.

Quote
From: Tirerack.com
Brembo Sport Drilled Rotors
Brembo Sport drilled brake rotors undergo the race-born practice of cross drilling to provide multiple paths to disperse built-up heat and gasses.

Quote
From:Answer.com
Many higher performance brakes have holes drilled through them. This is known as cross-drilling and was originally done in the 1960s on racing cars. For heat dissipation purposes, cross drilling is still used on some braking components, but is not favored or racing or other hard use as the holes are a source of stress cracks under severe conditions.
This reference can go on and on.....

My Answer to drilled rotors still stand to reduce heat..  :2c:
I do respect your opinion and you think what you want. With your way of thinking you can also say that the slot on slotted rotor are there to reduce weight, you are reducing metal off the rotor by having slots grove out from the rotor?  :poke:
Each modification being drilled or slotted have it own purpose, one reduces heat and the other reduces debris from the rotor
surface...  :)

I'll stick with the Indy and F1 experts on the subject and will steer clear of drilled always
Don't work as well and prone to crack

It would be a tough comparison to a stock sol because you have upgraded front calipers, larger rotors, so even with them drilled, there is more metal and better fluid.
