    The document discusses the brake system of a SYM T880 vehicle in a mechanics lab. It first describes the main components of the brake system, including the wheel cylinder, parking brake strut, brake drum, and return spring. It then provides an overview of drum brakes and their classification. The document also covers the purpose of brake systems and the two main braking mechanisms: foot brakes and parking brakes. It concludes with the technical requirements for brake systems and a comparison of drum and disc brakes.

    Classification & Specification

    The SYM T880 brake system in C3 lab is a drum brake ( Leading-and-trailing type )

    Fixed wheel cylinder

    Fixed anchor

    Due to the deliver part of the system, it can be consider as a type of parking brake (Foot brake
    sharing type)

    B. OVERALL ABOUT BRAKE SYSTEM

    PURPOSE
    The brake decelerate or stop a vehicle in motion, or prevent a parked vehicle from moving.
    BRAKING MECHANISMS
    a) Foot brake
     Overview
     Foot brakes are used to control vehicle speed and stop the vehicle.
     Disc brakes are used on front wheels while disk/drum brakes are used on rear wheels.
    Page |5

     Operation & Classification


    When the brake pedal is depressed  Create hydraulic pressure and operates as follows:

     Disc brakes : Stop the rotation of the wheel due to the friction which occurs when the
    disc brake pad pushes against the rotor.
    Page |6

     Drum brakes (which is the type of SYM 880) : The brake shoe expands. This stop the
    rotation of the wheel due to the friction which occurs by pushing of the brake lining
    against the brake drum.

     Classification of drum brakes: Depend on the leading and trailing shoe


    Page |7

    b) Parking brake
     Overview
     Foot brakes are used mainly when the car is parked.
     They mechanically lock the rear wheels.
     Mainternance items include the adjustment of the parking brake lever.

     Classification
    Page |8

    TECHNICAL REQUIREMENTS
     In order to ensure the safety of the vehicle and the ability of high-speed operation, the
    braking system must meet the following requirements:
     Good braking performance.
     Easy to operate, good directional stability during braking.
     Braking smoothness is good.
     Good heat dissipation, easy to adjust.
    …
    COMPARISON

    Comparision Drum brake Disc brake


    Pros - Cheap - More stable than the drum
    - Simple brake when braking
    - Closed in side the brake drum so can - Better at realeasing heat
    be prevented from bad weather resulted in long lifetime
    - Ability to power up (suitable with - Easier for mainternance
    heavy duty truck) - Lighter
    - Worn out evenly
    Cons - Worse at releasing heat so when - More expensive
    using in a long time can reduce the - Open to the atmostphere
    ability to brake so can be affected by dust,
    - Curved brake shoe  not worn out sand,…
    evenly - No power up ability
