how does it work?we're suppose to use the rear more because its rwd, but how come theres so much more brake dusts on the fronts?

 

Look at the size difference in both and you can see which end is doing most of the work, the fronts of course. In simple terms, it comes down to the weight shifting to the front of the car while stopping. You want both ends of the car to be slowing down at the same rate, so if there is more weight on the front of the car during a stop then naturally you need beefier brakes up there to dispel the energy.

 

No, that would be dangerous if our cars were brake biased more towards the rear than the front. What would you think would happen if you had to do a panic stop and let's say for arguments sake, 80% of the bias was towards the rear and your rear tires locked up? You would break traction first in the rear and your a** end would give out. Definitely not something the average driver on the road would know how to control. Read this great article on brake bias for more information.

All cars, RWD, FWD, AWD, the majority of the braking force is in the front. When you apply the brakes, the weight of the car shifts forward.

 

I agree with the above as far as brake bias goes -- braking in a straight line makes the fronts work harder, and that's why they are so much bigger. On the other hand, hard driving with the VDC on can actually wear out the rears faster. In addition to cutting power, another way the VDC works is to pulse the brakes on whichever wheel is spinning. I wore my stock rear pads down to the metal at a track day with the VDC on all day, and still had about 3mm left on the fronts. The front pads may also be made of a different compound than the rears, and that contributes to the extra dust.

 

yup, fronts ALWAYS do most of the work hence 34234x more brake dust on your front wheels vs rear wheels...

 

agreed, baised to the front, but VDC will wear out the rear first (depending on your driving style).

 

how come my rear brakes are squeaking though?

 

Your first question was answered adequately. So is your second question in context to the first question or just a seperate question altogether? The rear brakes squeaking has nothing to do with the bias that is set from the factory. Why your rear brakes are squeaking could be a result from a number of things. Maybe your rear pads are low and are at or near the minimum limit. Maybe there isn't sufficient lubricant on the back of the pads to absorb vibrations and noise while braking. If you are using aftermarket pads that are more metallic they will tend to squeak and squeal more than OEM pads. Maybe you just need to perform a "bedding" procedure to burn off a layer of glaze on your pads. Again too many things could be causing the squeaks, squeals. Check this page out for some details.
