Technical brake question

[Driv200]

Possible to get matching front brake calipers and front rotors put on the rear? Assming this would not mess up brake bias.

Virtually all cars have bigger brakes on the front compared to rear. I wouldn't mess with the mechanics of the brakes, although some have painted theirs (which shouldn't do any harm if done properly).

And here's a nice discussion about brakes that talks about why the front brakes are bigger than the back: http://www.wcengineering.com/articles/brakes.html

And here's a snippit from another post I came across: "A car that has a 50-50 F/R weight distribution at constant speed, can have 85-15 F/R weight distribution during braking. This means that the front brakes have to do a lot more work than rear. This is why the front brakes are usually a lot larger than rear brakes and why the braking system sends more force to the front than to the rear when you press the brake pedal. A correct bias exists when all four tires start locking up at the same time as you apply the brake. This makes sure that all four tires are delivering maximum braking force to the car."

If you ride a motorcycle you see this demonstrated by there often being two calipers mounted to the front wheel and one on the rear.

...and a motorcycle has two "brake pedals".

The handlebar brake handles the front wheel and and the foot brake handles the rear.

You can quickly see the result of braking with only one or the other, or the misapplication of braking, causing one or the other wheel to lock-up...which can easily result in "getting sideways" on a motorcycle.

The Genesis V8 has a 54/46 F/R weight distribution. The V6 is 52/48. This is one reason why the V8 has larger front brakes than the V6 (in addition to total vehicle weight being more for the V8).

Just about everyone who has owned a car long enough to need a brake job knows that the front brakes wear before the rears, even though the front brakes are larger.

I noticed that when I back the car up, stop, put it in drive, go forward then apply the brakes, there is a popping sound. Has anyone else had this issue?

As an ex motorcycle racer I can tell you that bikes often have 100% weight transfer. That is lifting the rear wheel clear of the pavement. A car has a lower center of gravity and will skid before lifting the rear. The Genesis has good anti-lock and should never harm itself in a panic stop.

This may be caused by the rear parking brake. Some cars need a TSB done to fix this issue. You may want to check this forum for threads on it.
