Rem behind your vehicle generally have brake drum type, although it is true by dozens which have changed to become brake
disc. Brake drum have grip energy which do not fail with brake disc, evidence if will try to pay attention big truck,
type put on the brakes what used, surely its answer is brake drum.
Drum brake component among others :
1. Cylinder Brake
2. Piston
3. Mechanism put on the brakes hand
4. Cable put on the brakes hand
5. Shoes Brake (brake lining)
6. Regulator brake lining mechanism
7. Drum
8. Spiral spring / Per.
Way of brake drum activity at the (time) of accelerate you depress pedal put on the brakes hence :
1. Rem master push oil put on the brakes which have compressible toward cylinder brake
2. Piston which there are in cylinder brake depress brake lining up at drum which is rotating
3. Spiral spring found on regulator mechanism follow length correspond to pressure given by piston.
4. After you discharge pedal put on the brakes hence pressure change rotatory brake drum will again push brake lining
5. And spiral spring will draw brake lining on course initially
6. Piston put on the brakes also will return to position initially
But brake drum type also have weakness, one of them is if across water pond, suffused water can enter into drum and paralyse
rem system, but only is tentative, tips for the you of is “after passing water pond, depress and hold up pedal put on the
brakes for a few moment”, and ascertain brake drum have nipped again.
