Cool Carbon Brake Pads

[bcredliner]

I think a discussion about pad stopping performance, fade and longevity should at least include the rotors and what improvements you have experienced.

As an example, if your concern is brake fade because of heavy towing, your goal may be a combination that someone has experienced less brake fade such as TiAGX5 posted.

Another example, I currently have crossed drilled and slotted rotors on the front only. I wanted the look, less dust and didn't want to lose stopping distance. I did only the front as they provide the greater percentage of stopping power. I knew that goes against the grain of many. I chose Baer Decela slotted and drilled rotors and EBC red stuff pads. I am not positive stopping power increased but I feel confident it has not decreased. I had previous experience with EBC pads with non crossed drilled/slotted rotors on both ends that I really liked. The stopping power improved and there was far less brake dust.

This week I will be installing the Baer/EBC on the rear and see what happens. I think the end result will be better than what I currently have.

I would be very interested in a combination of a drilled/slotted rotor and pads that improve what I have. If there is a downside to this combination, I think the stopping distance is better but it seems it is weighted to the backend of the stop. My logic is a combination that didn't do that would be even better.

Pads and wear sensor came today too. These are well suited to drilled/slotted rotors, hollow ceramic with high grade brass. Semi-metallic pads overtemp at around 550deg F and tear rotors/cheesegrate. The Cool Carbons major materials have greater thermal stability, allowing for pad contact temps of over 1100 deg F while not tearing up rotors/cheesegrating.

Gotta love parts that come with QS Certs showing insp stamps/sign offs/production and inspection dates all in German. Never seen pads with full QS certs.

The install is on hold because of high humidty, The silver DupliColor Ceramic caliper paint rattle can says only apply in low humidity.

I did, no application fit for the fronts from Cool Carbon for any 4.8is. The front pads are unique to this model so low demand. Bummer!

I would input the caliper/rotor PNs at RealOEM to see if those items were used on another model BMW.

Installed and heat cycled/burnished, got a good layer of pad transfer on the rotor. Refinished the pad carriers and calipers while it was apart.

Had these on the E46 and forgot how good they feel.

Before/after.

they look awesome, i really like the rotors too, nice quiet pads i assume? would def look into the cool carbons on my 3.0 when my pagids wear out!

Even assembled without anti-squeak they are silent (Cool Carbon has built in dimpled pad shims to control rattle/squeal, see pic a few posts back), just a drop of syn hi-temp brake grease on the slide points where the pads contact the carriers. This combo really pushes the caliper max open limit, with pistons fully seated, the pads fit over the rotors with about 1/16" clearance. Guess the rotors and pads are pushing engineered material max conditions.

Talk about the caliper refinishing. Looks brand new!

Thanks, the results blew me away too. 2 neighbors stopped in and saw them being removed nasty, came back over during final assembly and could not believe they were not new.

The refinishing turned a 2 hr job into a 6 hr job (dry time not included). Used the 5 pc wire wheel set for cordless drill (Harbor Freight). Removed everything. Depressed the brake pedal 1" (little trick, this keeps gravity from draining the res fluid down to the calipers), Plugged the caliper ports with 10x1 cap screws with 3/8 rubber grommets (to seal the fluid inside and keep crud/paint out), slipped rubber 3/8 vacuum caps over the threaded ends of the brake lines.

DupliColor has rattle can ceramic brake paint, only $7. one can did them all. Went with the silver/aluminium because it's close to the OE color.

Cool! Thanks for the very complete info! Your results look fantastic!
