Why were drum brakes used originally
They could be mechanically operated
They looked cool
they have a greater efficiency than other brake types
They are heavy
Drum brakes have another advantage that has seen them stay in use despite the advancement of disc brakes
They out perform disc brakes in dry conditions
They are more expensive to produce
The self servo action makes them very good for Handbrake applications
They work better in reverse
Despite the universal acceptance of Disc brakes they do have draw backs
Lighter and less effective than drums
They do not work well in the wet
Require intensive servicing to maintain operation
They are heavier and more expensive than drums
There are two main types of disc in use
Solid and Vented
So Solid Crew
Drilled and Slotted
Disc and Drum
What is the usual minimum thickness we change brake pads at
0.5-1 mm
1-1.5 mm
8-9 mm
2-3 mm
Which component is responsible for for pulling the brake pad away from the disc after the driver releases the pedal
Hydraulic pressure
The seal around the piston
Brake springs
Pad Pushers
The master cylinder has one main job that is too
Convert kinetic energy into heat
Convert mechanical movement into hydraulic pressure
Convert hydraulic pressure into mechanical movement
Convert electricity into braking
The master cylinder is usually fitted with a reservoir this allows for
A reserve of fluid is kept in case of leaks
To reduce the driver effort
To allow for brake pad and disc wear
To stop the fluid absorbing water from the atmosphere
Where are tandem master cylinders used
On bicycles with more than one seat
On vehicles fitted with single line braking systems
On vehicle with split line breaking systems
On vehicles with split line braking systems
The brake servo is fitted on vehicles with disc brake systems its job is to
Increase the efficiency of the braking system
Increase hydraulic pressure
Reduce the hydraulic pressure
Decrease the effort required by the driver
A sign that the servo has failed is that
The brake pedal becomes soft
The brakes do not work
The pedal remains hard but the brakes still work
Only the front brakes work
The brake system is usually fitted with flexible brake lines this allows for
Easy component removal and refitting
Allows for steering movement
Allows for suspension movement
Allows for steering and suspension movement
Vehicle brakes usually do more work at the front than the rear the average split for braking effort is
90/10 Front/Rear
80/20 Front/Rear
60/40 Front/Rear
50/50 Front/Rear
Cars up to 2010 must meet a minimum braking efficiency of
50%
58%
16%
80%
What Safety feature has become a legal requirement since 2010
Traction Control
Stability Control
ABS
Electronic Handbrakes
