Actually, a lot of motorcycles do have disc brakes in the rear now. Traditionally this was not the case just as it was not in cars. Things are changing though. The front wheel does most of the stopping in any case.
It is a fact that both disc and drum brake systems have improved considerably.Also about 60 to 80% of breaking power comes from the front wheel.So using a disc system in the front wheels and a drum system in the rear wheels is sufficient for a good breaking effect.Also it will reduce the cost.
So, finally, using a disc sytem in the front and drum system in the rear will provide good breaking effect at reduced cost.
Though the 2 wheel disc system provides more breaking effect, it is not required unless we are in a racing track.
When disc brakes are applied, a caliper squeezes the brake pads against the disc and the wheel slows. When drum brakes are applied, curved shoes located inside the drum are pushed outwards, rubbing against the inside of the drum and slowing the wheel.
It would depend if your car has 4 wheel disc brake or only the front (2) has disc brakes. You would have one rotor for each wheel with disc brakes.
Behind the wheel holding the disc brake pads.
As long as the brake is strong enough to lock the wheel, you can skid with any brake design.
Take the wheel off to see if you see a caliper for a disc brake or a drum for a drum brake.
Most modern cars have disc brakes on the front wheels, and some have disc brakes on all four wheels. This is the part of the brake system that does the actual work of stopping the car.The disc brake is a lot like the brakes on a bicycle. Bicycle brakes have a caliper, which squeezes the brake pads against the wheel. In a disc brake, the brake pads squeeze the rotor instead of the wheel, and the force is transmitted hydraulically instead of through a cable. Friction between the pads and the disc slows the disc down.Vented disc brakes have a set of vanes, between the two sides of the disc, that pumps air through the disc to provide cooling.
Most front wheel drive vehicles do. -The caliper in all vehicles is fixed and the 'floating disc' is the brake rotor.
1995 Mercury Cougar does not have front wheel brake shoes. It has disc brakes and therefore disc brake pads. Copy & paste this link into your browser. http://www.advanceautoparts.com/english/youcan/html/ccr/ccr20021101db.html
A 'brake' is a device on a vehicle or machine to stop it's motion. On a car or truck, a brake is typically attached to each wheel and mechanically clamps a disc or rotor to stop the wheel turning.
You need the relevant operating system and a wheel that will take a disc rotor .
easy job ,,,take the wheel off then undo and take off the calliper, then the disc comes off.......
Remove wheel, brake caliper, brake disc, parking brake shoes etc. Drive out broken stud, replace with new stud. Replace above in reverse order.
