If You Replace The Master Cylinder It Will Help You With That Problem. Me An My Buddy Have 05's And He Put On A 16mm Brembo Radial Master Cylinder It Fixed The Brake Fade. Im Looking At A Full Brake Kit From Beringer To Fix My Problem. Thank God I'm A Lockhartphillips Dealer Other Wise I Would Be Broke. Hope This Helps

 

I went with a 16mm Brembo master cylinder and Magura Caliper ( from site sponsor Factory Pro Racing). Now, if I could get my bike to run longer than 4-5 laps without sputtering to a stop, I'd tell you what I think of the brakes.

 

How big is the stock KTM M/C? 13/14/15/16mm's????

 

i think its between 12mm and 13mm

 

How big is the stock KTM M/C? 13/14/15/16mm's????

17.46 mm or 19.05 mm

Jim,

Sometimes I think you are the guy on the Comcast commercial that finishes the internet, you always see to find stuff noone else knows.

Master cylinder Ø: 17.46 mm for one caliper 19.05 mm for two calipers

Thanks!

Kurt

PS when are you coming out to the track??

 

Anyone here used the EBC brake pads on the stock SMR front brake caliper? I find them to be half the price of the KTM stock pads but the get glazed very quickly, start squealing and loose their stopping power. Anyone have a solution?? I think the EBC part number is MSX405.

 

Also...anyone know if the Brembo 19mm will work well on SMRs? I've seen reference to a 16mm Brembo master in this thread, but not a 19mm.
Brembo Piston size is 19 X 18. Part no. 250-1020.

 

I think the Brembo 19mm would make your brake feel like poop. I belive the issue with the fade has more to do with the fluid being over temp than the MC being sized wrong.

Maybe I should pop for one of those cool brake scoops Jim found in the bowls of the internet and see if that helps.

Do the EBC pads have a backing plate on them?

 

The EBC pads are complete shite. They ones for the 625SMC caliper are the same crap compound and were just as useless after ten hard laps. I tried everything I could think of to resurect them, but they never lasted more than a few hard laps.

They were cheap though, so I bought several pair. Now I give them away at the track to guys I DON'T like...

 

Kurt, this what you get with part number 59412048000 and your $109

 

I am very interested in this info!
I too had brake fade...
and on the dragon...
... it sucks!:Funny:

Let us know the details when you get it, PLZ! :thumbup:

The 19mm will push to much fluid for a single caliper, making the lever rock hard and requiring more lever pressure.

 

Mooner...I have an 055 KTM 450SMR. Is that kit different than what I already have on my bike? And if so, what is the diferrences? Why is it better? Thank You

I don't have the brake performance kit, as I use the Magrua caliper. But from what I read the kit is suppose to take care of some of the braking issues that the 05 FTE caliper has.

 

I just got my 05 525 SMR last saturday. I rode it yesterday for the 2nd time, and after a couple hard laps the brakes faded bad. I really wasn't expecting that to happen so soon. I need to fix this.

 

So let's have a poll... Is the problem part the:
a) master cylinder
b) caliper
c) both
d) neither, operator error

Does anyone that races one of these bikes actually have no problems? If so, how did you manage that? I want better brakes but don't have deep enough pockets to just throw cash at the problem and hope for the best

 

How about fluid? Atol Super Blue is the bestest stuff in the world. I have used it on all my roadrace bikes as well as my tard. You can't boil the stuff. Given that all things are new on some of these bikes that precludes the normal change the pads, clean the calipers, swap out to stainless lines advice I'd normally give. The only thing left is the fluid.

 

motarded - I'm using Motul 600 high temp brake fluid and it has helped. But even with that it seems you have to bleed those darn things every race.

I don't know if the EBC pads have a backing plate as I don't know exactly what you mean by that. They are just pretty standard looking pads, the pad material attached to the steel caliper fitting.

 

Motul 600 here, bled extensively at the m/c and at the caliper. No stock fluid remaining... They have faded away completely (lever to bar) on the kart track and at Homestead. I bleed them and it helps, but not for long. One guy suggested I teflon tape the bleeder screw as he hypothesized air might get sucke in as I bleed due to coarse threads. Another guy told me not to do that because if any of the tape comes apart and floats away in the system, I could have big problems... I'm ready for a good hardware suggestion or two Is it possible to run sport bike brakes? They seem very bulletproff and plentiful...

 

I am gonna make an aluminum air scoop for the caliper and put in some good fluid and see what happens.
the bike is brand new (2 rides) and after about 8 or 10 hard laps the lever went to the bar, sucks.

 

Can anyone who is having this issue hoist the front wheel up and tell me approximatly how much drag you have? If you give the wheel a good spin, how many times does it go around?

 

I spoke with a couple of knowledgeable people today who both told me it was the m/c. I am going to switch to a Brembo 13mm intergral reservoir m/c after the race at Jennings this weekend and if my problems disapear, you all will be the first to know. Of the Factory Husa hot-dogs I know of, Loire runs a full-boogie billet Brembo setup (~$2,000...), Iddon runs the Beringer 12mm intregal res radial m/c (BRO12) and 4 piston radial mount caliper.

 

Brake fade is caused by the fluid boiling, correct? so how does the master fix the problem? I would think that good fluid and cooling the caliper would help. Dont the KTM's come with Motorex 5.1 fluid?
