Brake Components & Remarks

Components

• All 4 Disc combination used to

achieve 4 Wheel Lock .

• Disc Used – Apache RTR 180

(Rear)

• Caliper Used – 3Apache RTR

180 (Front) and 1 Honda

Aviator

• Master Cylinder Used – Maruti

800 Bosch Tandem Master

Cylinder (OEM)

• Aluminum Brake Lines,

Hydraulic Brake hoses, Banjo

bolts etc.

Remarks

• The Disc and Calipers being

used are the same as previous

year. The reason being its

Reliability and to ease up the

Budget. (Spares will be bought

in case any malfunctions.)

• This particular combination of

Calipers is chosen due to its

Ease of Mounting Bleeding

points on top.

• Bosch Tandem Master cylinder

is used because of its

Compatibility with the Calipers

and BAJA recommends use of

OEM.

• Diagonal Braking Circuit Split

used so that braking power is

available on both Axles in case

one Circuit Fails.

VARIATIONS IN DESIGN

VARIABLE CHAMBER MECHANISM - The variable camber mechanism is a

modification in the front suspension design which will allow us to vary the camber angle at will. This is done through using adjustment bolts which will help vary the distance between the upper knuckle joint and the chassis. Camber can be varied in test runs and the optimum camber can be decided for the particular condition.

INDEPENDENT FENDERS-The fender is a removable attachment to the A-arms of the suspension which help to block dirt & sludge away from the driver. It is mounted on the A-arms using pipe brackets hence avoiding drilling of any holes. The assembly is spring loaded allowing it to undergo slight deflections and not making it rigid and prone to failure.

SAE INDIA BAJA

Baja is an inter-collegiate design

competition organized by the Society of

Automotive Engineering (SAE)

Provide Indian students with a

standard platform to showcase their

talent and potential not only in terms of

design and engineering, but also their

capability for team-work, entrepreneurial

skills and management.

The contest challenges each team to

function as a firm, whose task is to

design, fabricate, market and race-off an

off-road vehicle that will be evaluated on

a variety of manufacturing angles.

The vehicles are judged based on their

ability to maneuver and transverse harsh

off-road racing course while not

succumbing to the rigors of it.

TEAM KASHPIERS @ DSCE

» Started in May, 2010.
