Brake System( disc, dyum,bleeding...)

Composition

The brake system consists of the control system, hydraulic system and power system.
1.Control system: pedal, handbrake                                                          
2.Hydraulic system: brake pump, hydraulic tubing                                            
3.Electronic control system: ABS pump, ABS sensor, ABS computer                             
4.Execution System: brake calipers, brake pads, brake discs

Type: Disc brake & Drum brake

drum brake:

Drum brakes, use a wide cylinder that is open at the back, similar in appearance to, well, a drum. When the driver steps on the brake pedal, curved shoes located inside the drum are pushed outwards, rubbing against the inside of the drum and slowing the wheel.

dice brake:
Disc brakes,use a flat, disk-shaped metal rotor that spins with the wheel. When the brakes are applied, a caliper squeezes the brake pads against the disc, slowing the wheel.

What is the difference between disc brakes and drum brakes?

Disc brakes are generally considered superior to drum brakes for several reasons. First, they dissipate heat better (brakes work by converting motion energy to heat energy). Under severe usage, such as repeated hard stops or riding the brakes down a long incline, disc brakes take longer to lose effectiveness (a condition known as brake fade). Disc brakes also perform better in wet weather, because centrifugal force tends to fling water off the brake disc and keep it dry, whereas drum brakes will collect some water on the inside surface where the brake shoes contact the drums.

Bleeding

1 Clean out reservoir

2 Top up with new Fluid

3 Select DOT

4 open bleeder nipple

5 place block under brake pedal

6 pump 6 times, hold down.

7 Open nipple and close again

8 Pump 6 times and hold down

9 Open nipple and close again

Factors when considering brakes

1 Weight
2 Speed
3 Road surface
4 Tyre condition


Working principle

1 General principle kinetic to heat energy
2 Force on the brake pedal.
3 Forces the push push rod in the brake booster which in turn forces the primary piston in the master cylinder forward, the fluid pressure presses on the secondary piston
4 The brake pipes carry the fluid pressure to proportioning valve then to the brake caliper
5 The piston forces the brake pad against the Disc-Rotor
6 The friction reduces the rotor speed
7 The wheel being attached to the rotor is there fore slowed down.
