COMPONENT PARTS OF BRAKING
SYSTEM

9. INTRODUCTION
All cars have several systems.
They are mandatory, and they will be
present as long as cars exist. One of them
is your brake system. Brake system
components may vary depending on the
make and model, but generally, they work
in the same principle.

10. INTRODUCTION
Today we will help you
understand all about the components and
why they are important. Your brake system
must be in perfect condition 24/7/365.
The following are the parts of
your vehicle's hydraulic brake system.

11. DIFFERENT
COMPONENTS OF
BRAKE SYSTEM

13. 1. BRAKE PEDAL
It is the pedal that you press with
your foot in order to make a vehicle go
slower or stop. The brake pedal is located
on the floor to the left of the accelerator.

18. 2. HYDRO-VAC POWER
BOOSTER
It provides additional force to the
brake pedal which result of easily acquired
pressure needed to apply brake. These
vacuum booster receives via a vacuum
system attached to the engine’s intake
manifold (Gasoline Engine) or alternator
(Diesel Engine).

23. 3. BRAKE MASTER CYLINDER
It is located in the engine
compartment on the firewall. It consists of
fluid which compensates for any change in
fluid volume in the pipe line. When sufficient
pressure has build up, the inner rubber cup is
deflected, forcing the fluid in the lines,
thereby it applying brakes.

27. 4. BRAKE FLUID
It is a special oil with some specific
properties. It can withstand cold temperature
without thickening as well as very high
temperature without boiling. The current
standard is DOT-3 (Department of
Transportation) which has a boiling point of
460oF.

30. 5. FLUID LINES
These are the series of steel tubes and
rubber hoses through which brake fluid
travels. Rubber hoses are used only in places
that requires flexibility such as front wheels. Its
dangerous to use brass fittings or tubing to
repair brake lines.

34. 6. COMBINATION VALVE
It is combination of proportioning
valve and pressure differential valve

36. KINDS
OF
COMBINATION
VALVE

37. A. PROPORTIONING VALVE
These are mounted between the
master cylinder and rear wheels which adjusts
the pressure between the front and rear
brakes.

40. B. PRESSURE DIFFERENTIAL VALVE
It mounted just below the master cylinder,
it measures the pressure from the two section
of master cylinder and detects a malfunctions
if any.

43. 7. WHEEL CYLINDER
It is a component of a hydraulic drum
brake. It comprises a housing made from
made from grey cast iron or aluminum. Its
function is to exert force onto the shoes so as
to bring them into contact with the drum and
stop the vehicle with friction.

48. 8. CALIPERS
It used to stop the vehicle by applying
clamping force with brake pads to the
rotating rotor disc.

52. TYPES OF CALIPER
ASSEMBLY

53. A. FIXED CALIPERS

54. A. FIXED CALIPERS

55. A. FIXED CALIPERS

56. B. FLOAT CALIPERS

57. B. FLOAT CALIPERS

58. B. FLOAT CALIPERS

59. 9. BRAKE PADS/SHOES
Brake pads are a component of disc
brakes used in automotive and other
applications. Brake pads are composed of
steel backing plates with friction material
bound to the surface that faces the disc brake
rotor. Brake shoes are part of a drum brake
system.

62. 9. BRAKE SHOE/PADS
Brake shoes are crescent-shaped
components with a rough friction material on
one side. They sit inside of a brake drum.
When the brake pedal is pressed, the brake
shoes are forced outward, pushing against
the inside of the brake drum and slowing
down the wheel.

65. 10. ROTOR DISC
It is the rotating part of a wheel's disc
brake assembly, against which the brake pads
are applied.

70. 11. BRAKE DRUM
It is a heavy metal covering fitted over
an automotive brake assembly and fastened
to the axle: used in a braking system (drum
brakes) in which internal brake shoes are
pushed outward to contact the spinning
drum from the inside see also disc brake.

74. 12. BACKING PLATE
It is a metal plates that function as the
solid foundation for drum brake. Made of
steel, these plates have the wheel cylinder
mounted on them to which the brake shoes
are then attached.

79. 13. WHEEL HUB
It is to keep the wheel spinning freely
on the bearing while keeping it attached to
the vehicle. It is the only part that actually
holds the wheels to the car.

82. 14. WHEEL BEARINGS
It is a crucial part of the wheel
assembly that connects the wheel and the
axle. It is a set of steel balls (ball bearings) or
roller (roller bearings), held together by a
metal ring. It enables the wheel to rotate
smoothly with a minimum of friction.
