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.
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.
How much of the braking is typically done by the front brakes in a front-wheel-drive vehicle?
10% 30% 50% 70%
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
What model or make of car you can get disc brakes off of to replace front drum brakes on a 1969 dodge coronet?
68, 69, 70, coronets, or chargers disc brakes will fit.
Do you have to replace the back brake shoes if you change front pads?
No. You will only need to replace the brake shoes if they are worn down. Generally the front brakes do 70% of braking leaving the rear with 30%, which will cause the front pads to wear first. What is important however is that you replace either front brakes or rear brakes as a set. i.e. if you're replacing the front brakes do the right and left side.
Are the disc brake pads different sizes on front than rear of a 2006 mercury mariner?
i am not very familiar with this type of car but front brakes do about 60-70% of your braking thus requiring a larger pad, so logic suggests that your front brakes are larger then your rear brakes Front pads on almost any vehicle are larger.
How much do new brakes cost for a 350Z?
The front original Nissan brake pads cost $70. R-ZEE.
How much should I pay for front brakes?
On average car, under $100 dollars is reasonable. Maybe around $70?
How dangerous is it to ride a motorcycle with no front brakes?
If you are going over 10 mph it can start to get very dangerous because most of the stopping force applied to a motorcycle is from the front brake (estimated 70%). The back brake can lock up easily.
How much does the average brake replacement cost?
I just had the front brakes 'done'. I called about 6 places, some named brand and some 'garage', and the average cost was about $130-$140. This includes new pads and resurfacing. Also realize my front brakes are disc brakes, my rear brakes are drum brakes. Drum brakes are about $50-$60 more. They broke it down to $60 parts $70 labor.
Why do you use front disc and rear drum brakes?
Front brakes provide about 70% of stopping force. Disc brakes have an advantage over drum brakes in that they can provide more stopping force without overheating (and thus loosing their stopping efficiency). I believe drum brake units are less costly to manufacture than disc brakes, so using them on the rear also saves manufacturing costs.
