MS3 Braking systems

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
