To the FRONT of the vehicle
Probably braking hard.
Possible broken a-arm, or bent wheel.
10% 30% 50% 70%
replace front brake rotors and pads.
If memory serves, the typical braking force ratio for any automobile with front disc and rear drum brakes is 60% front, 40% rear +/-.
what would cause a rubbing noise on drivers side front wheel especially when braking ( I replaced rotor and wheel bearings are good) ?
What percent of braking are front wheels responsible
Primary brakes are situated at the front wheels and provide about 70% of a vehicle's braking power. Your secondary brakes are located at the rear wheels and only provide about 30% of a vehicle's braking power.
EBD: Electronic Brake Distribution (or Electronic Brake-force Distributor) - alters how much of the brake force goes to the front and how much to the rear. Cars always have more braking on front as if the rears lock before the front then the car will spin. How much braking you can do with the rears depends on how much weight is in the vehicle so EBD dynamically adjusts this balance. Without it, the manufacturer sets up the balance so the rears don't lock when the vehicle is empty which is less braking than is possible when the vehicle is full.
There should be more braking power to the front wheels for two reasons. As the brake is applied there is a change in the balance of weight distribution on all four tires caused by the vehicle pitching down on the front. This places more weight on the front tires. If there was more braking taking place on the rear tires than on the front, there would become an oversteer condition and the back of the vehicle would skid out.
