Where would inertia cause the weight of a vehicle to shift during hard braking?
During hard braking, inertia would cause the weight of the vehicle to shift forward towards the front wheels. This is because the momentum of the vehicle is being slowed down, leading to a weight transfer from the rear wheels to the front wheels.
Steering wheels shakes when braking?
You need the front rotors machined or replaced.
What skid occurs when the brakes are applied so hard that the front or rear wheels lose traction?
Braking
What is the difference between primary brakes and the secondary brakes?
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.
Which pair of wheelsfront wheels or rear wheels does stop when you apply handbreaks and which pair stops when you apply breaks?
On most cars the handbrake is applied to the rear wheels only. The footbrake applies to both the front and back brakes, with a bais to the front to help avoid the rear wheels locking up under heavy braking.
What kind of skids occurs when the brakes are applied so hard that the front or rear wheels lose traction?
For rear drive cars - it's called a fishtail. You brakes work better on the front. Anybody who sailed over the handlebars when braking just the front wheel on a bike is called a head plant, (ouch)
1978 corvette with frustrating front brake problem Good fluid flow to both wheels but when braking car pulls severely to left Caliper pistons appear OK but little braking power to left front wheel?
sounds like your brakes need bleeding properly
Why are disc brakes normally used on the front?
disc brakes are usually used on the front of a car is because the braking ratio for any Car is 70 / 30 ........70 percent of the braking power goes to the front 30 percent goes to the back also if you had disc brakes on the rear of the Car and you slam on (emergency stop) the brakes would lock and you would slide all over the road
Why aren't hydraulic brakes used for rear wheels when the same is used for the front wheels?
All modern mass-produced cars and light trucks DO have hydraulic brakes on the front and the rear wheels. Heavy trucks generally have air brakes on all the wheels. Maybe you are thinking of cars that have disk brakes on the front and drum brakes on the rear? On cars, these are both hydraulically operated using the same hydraulic (brake) fluid. In normal stopping situations, the front brakes do more work than the rear brakes. Maybe 70 or 80% of the braking is done by the front wheels (it depends on where the weight is in the car and how fast you stop). Disk brakes are a somewhat better brake for a car, but drum brakes are a little cheaper to manufacture. So, disk brakes are almost always used on the front wheels where the braking is more important. Drum brakes are used on the back of some cars to save money. Note that performance cars (sports cars) almost always have disk brakes on all of the wheels.
