[QUOTE="Rmc, post: 1849693, member: 39072"] Funny thing drum brakes don’t require calipers . And the required space between brake drum and wheel is smaller then the area of required space between rotor and wheel because a caliper has to be Inbetween the rotor and the wheel. Federal regulations such as reduced stoping distance , four wheel abs among others lead to vehicle manufacturers moving from rear drum to rear disc brakes. More stopping force is applied to the rear axle of a vehicle then the front axle to maintain steerability . Increased stopping force required bigger pistons in the rear calipers. It is common to have smaller calipers and brake pads on the front axle of pickups and larger vehicles then the rear axle . Some may have same size front and rear but not smaller on the rear. Basic science says increased stopping requires increased force and or increased stopping surface. Not hard to understand most stopping force is applied to rear axle . So more stopping force is required at rear axle then front axle. Only so many ways to increase that force . Leading to larger calipers on rear . Meaning bigger wheels to be allow for more larger calipers. [/QUOTE]
