ASK AJ Noud about rear brake failure at a test in California (Moran). He hit turn one at over 85 miles an hour, flipped over the fence, and landed on the hay bails. NOT PRETTY.
So THAT’S what happened to AJ! 😆
All kidding aside and it’s been said time and time again. If you test and tune you’ll be fast if done properly. Front Brakes isn’t this year’s “magic bullet” to be faster. But I would like to hear DOUG WELCH’S 10 cents as to a heat sink on the axle… Welch??? Welch???
RB is right on this one. Puting a rotor in the center of the kart does affect a lot of things, including the flex. Many tuners use stiffeners in the center as a way to move the flex to the outside of the bearings.
The bearing acts as a fulcrum point. As the axle flexes upwards under cornering, the center part flexes downward. This is how our Pro axle works, thicker in the center, thinner outboard of the bearings.
But there is another problem with putting a rotor in the center. It too involves axle flex but what happens is the flex distorts the rotating plane in which the rotor spins. Yet the caliper is fixed. So what will happen is the rotor will rub on one of the brake pads creating drag. That is the main reason the caliper is moved so close to the cassette. The farther you mount the rotor away from the fulcrum point, (bearing), the farther you have to retract the pads to prevent rubbing. This greatly increases the pedal travel you need.
Mike wants to know about the heat sink. I’m not sure how valuable they are. I’ve used them, they do seem to reduce heat. But a better solution maybe to just better maintain the brakes.
I found out some interesting info in the past week. Dot 4 and 5 oils do have higher boiling points that Dot 3. However, they also expand more at a given temp than Dot 3. We also use steel brake lines that do not expand when pressure is applied. This creates problems in kart brakes.
If you fill the resevouir to the top, there is no place for the hot oil to expand in to and it causes the brakes to drag. Also, most Euro brakes are not designed to use silicone based fluids and that causes the seals to expand, creating more drag. The best solution is to use a quality Dot 3 and change it out regularly.
thanks Doug, you da man. Great Info
Oh and by the way, i think you’re the William Macy part in Wild Hogs… I’ll let you know if I still feel that way Saturday…

Eduardo, are you and the rest of the International Brokers team coming out to practice on Sunday?
If not..perhaps you are afraid of my DOMINATOR kart? I had a great time racing with your team last time out.

Dustin and I are coming out to rub wheels with ya Kirk….get ready :rotate:

Pssshaw…you better bring your A-Game, I’ll be rocking the DOMINATOR. Sunday, right? That will be a blast.
For those who don’t know, I am driving Chuck’s old Easykart. And now I’m going to embarrass him in his new slotax kart. :cheers:

Sounds like the gloves are off! :argue
Kirk,
If you want to see the Dominator rock, strap Dustin in for a few laps. :cheers:
Actually I may ask him to drive mine for a few laps so i can see what the KART is capable of and how far the Dominator Driver has to go to reach ‘par’. Once he smashes my fast-lap by 4 seconds, I’ll then start screaming that I need front brakes..that HAS to be the reason I’m slow! 😥
I know he’s good. Never met him though.
I’ve still got about 20lbs of Centennial mud to clean off the kart from the last geo-sampling mission. I’m psyched.

Also Mike Jansen may have some helpfull hints on removing large amounts of mud from your kart! 😆
