Thats the wrong procedure!

Select your rotor(brake disc) first and then design the wheel hub! Cheers!

Fabricate ur own disc as per ur requirement, thats's the only option.

@ mayank11 : Kindly follow Mehul's advice, getting into the business of fabricating your own brake disc will only cause wastage of precious time,money and energy. Over the years we have used Pulsar and Apache brake discs, which have worked pretty well. Although you might have to make a spacer according to the hub you are using.

Concentrate on getting the car up and running as soon as possible, then test! test! test!

On a side note, i think making your own hub might be more beneficial than a brake disc.

Here is something that I've made for my team : http://www.scribd.com/doc/5658...=q93x1rmnlff8uzunwgv

Thought i'd share it here:
1. To improve co-operation between Indian teams and encourage everyone to "open up", so that we can all improve faster.
2. To help new team avoid similar mistakes.
3. To let new teams know what kind of infrastructure, facility & equipment is required - many Indian teams over-estimate the facilities of their college workshop and are ill equipped during the competition (without tools and camping stuff)

in 2006 we had this disc (i think it was Victor's or may be Unicorn's ). It had an eccentric flange which saved us from trouble of spacer. The diameter and thickness were also compatible with Wilwood PS calipers.

Unfortunately, the bike model was not continued and later we had problems finding the same disc.

Concentrate on getting the car up and running as soon as possible, then test! test! test!

@Pradeep

Your report on the progress of Formula Manipal is excellent !

The list of common pitfalls and design errors which you provided was very valuable for us. We have managed to avoid most of the errors on the list, especially regarding driver comfort, cockpit space, fuel tank cap O-ring, clutch pedal stoppers, lock nuts, steering column mounting bush and putting right size of bolts on critical parts.

However, I think that we have made the car too heavy with preference on safety. Lets see how much weight we can shave off in the next few days.

Im glad you found it useful


Also a heavier car is in no way safer than a lighter one .

From past experience
Year: 2009
Logic:
1) Heavier car is safe
2) when in doubt increase thickness
Result: 300kg+ car

Year: 2010
Logic:
1) Hand calculation of loads using tire data, approx engine torque, driver forces
2) Simulate using FEA
3) Add some factor of safety
Result: ~250kg car

Year: 2011 & beyond
Logic:
1) Find accurate loads using DAQ, tire data and lap simulation
2) Simulate using FEA- static, dynamic & fatigue forces
3) Add minimum factor of safety
Result: hopefully near 210 kg

Anyone ever tried MMC in brake system ??
