What exactly do I need to do to prevent overheating of the front brake? Jdugger, I can already hear you telling me I have to give it more gas before I have to worry about my brakes overheating. Haha. I know I won't be able to keep up with you, but I want to work on my pace this year. I don't want to worry about my front brake fading as I improve my track pace. What is most important? Is it the upgraded mounting hardware? Does the 5mm finned rotor make much difference? I have a new set of stock brake pads on the shelf in my garage. Are these still OK to use? I know I am not fast, but I plan on going just a little faster this year. I need to replace my front pads before I go to the Dragon VII event, so I figured I would just upgrade whatever is needed. Thanks!

BTW, my front brake is currently a completely stock setup the way it left the assembly line in 2008.

Rotor, mounting hardware and 2015 compound pads is what I went with. Just a bit short of $500 at the time, the rotor is considerably more now.

But, if you get an 1190RX, it comes with a nifty brake cooling duct, I bet that would help as well. : )

I'm running same set-up as Dean: Finned rotor, 2015's and the EBR mount kit. I was bummed when rotors almost doubled in price.

PM - when you say 'overheating', do you mean gets hot, or hot to the point of brake fade? They do get hot - 'normally' to the point that the rotors start turning purple and yellowish colors. Change and bleed brake juice often, use quality juice (I like the Motul), and you should be OK.

I'd also suggest checking to make sure you don't have brake drag...after a while the caliper needs a rebuild or at least thorough clean to ensure pistons aren't sticking.

I forgot that part, I put Motul RBF600 in mine at the time I did the brake upgrade. I think there's one rated a little higher for boiling point, maybe 660.

I just want to have confidence that my front brake will be OK if I pick up the pace to the point that I am using it more. I have no problems with it now. I don't want any if I go faster. I regularly flush the fluid, and keep the caliper clean. I have never had any issues with dragging brakes or pulsating disk.

RBF600 Fluid

Hardware upgrades mentioned.

Talk to me at the track and I'll step you through it.

RBF600 fluid, new brake disc, and new mounting hardware ordered. The 2015 pads are listed as race use only. Why is that? Are the stock pads no good? I have a new set on the shelf. I will have no problem putting it all together. It is much easier than changing out the water pump.

This is good stuff. It will do more for the feel and performance of the brakes than anything else. A master cylinder upgrade would be another nice change, but it isn't absolutely necessary, although you might be due rebuilding yours (cheap) to keep performance at peak.

The 2015s are probably listed race only because they don't have DOT approval, but I don't know. Some race pads will actually perform worse in street applications because they don't get hot enough and glaze. I've never run the 2015 on the street, so I don't have practical advice for you here.

The OEM pad is actually a moderately aggressive pad. It's not a bad choice for occasional track days, especially if you aren't in the quick group just yet. It dusts a lot, though...

JD is a brakin' fool (love ya buddy) in that he's pretty hard on brake hardware. I have noticed that the 2015's wear much better than the stockers under track/race conditions. In my case, at least double the life of stock pads. (I only know this because I had some extra stock pads laying around that I ended up using when I had no better option on a race weekend) My season is shorter than his, the tracks I run are different, and I don't ride as aggressively or as fast, so there is no apples to apples comparison. I can get pretty much an entire race/track day season out of a set of 2015's - maybe two or three weekends on stock pads.

Would an upgrade in pads be sufficient? I am looking to do a few track days this year along with street riding. I had been a big fan of the EBC HH pads on my Japanese track bikes and they served me well.
