I notice that I get alot more fade on the rear brakes. Whats the ratio of the Front Braking compared to the Rear?

How exactly are you noticing that your rear brakes fade more?

With a stock braking system, the fronts would fade first due to the ratio of braking power.

??? huh? its called brake dust covering the rear wheels and non on the front ones!
Anyways, maybe the emergency brakes been catching *shrug*
I know on FWD cars that its about 70%front and 30% rear braking power.
I didnt know if RWDs were the same.

That doesn't mean you have fade; rynberg is just trying to help you out. Brake dust has nothing to do with brake fade. Fade is when the brakes overheat and loose braking force.

First check to see if the rear wheels turn freely while the car is on stands to verify the e-brake is free. If the wheels are not hanging up then what type of pads do you have front and rear?

Hi Eric, if you're seeing significantly different amounts of dusting, it may just be that the front brake pads have been replaced with something besides OEM pads. This could also affect brake performance and potentially lead to some fade effects, but the amount of dust is not the same issue.

Almost all street cars will have significantly higher front brake bias because, (1) the weight transfer under braking means that the front brakes do more work, (2) its considered 'safer' to lock the front brakes than the back (because locking the back tends to make a car swap ends), and (3) anti-lock brake systems work better when the bias is set even higher toward the front than non-anti-lock. (Remember the videos showing cars going straight ahead while trying to perform panic stops in the water).

Maximum stopping power comes just after the tires starts to slip a small amount. Not fully locked, but no longer rolling at the vehicle’s full speed either. It's tuff to achieve this in a street car, and even some race cars. Generally anti-lock aids in handling during emergency braking situations, but at a real and measurable small loss in absolute stopping distance. For the 7 and most other street cars this means the front brakes lock well before mazimum braking is achieved by the back tires.

David, thanks for the insight.
I was watching HorsePower TV on TNN and they were saying the same thing basically. That because the weight is pushed forward, more demand is on the Front brakes. I think my emergency brakes been rubbing, cuz Im always having to bring it down.
