My question is the effciency of them on a car, but suppose your car weighing in around 500kg's doing around 60-100mph flat out? compared to a bike about 200kg's doing 200mph is not far off!

That's the logic I'm working with, although whether it's sound physics I don't know.

The larger diameter would have a greater mechanical advantage as well, but anyone who can do the maths or can put the question to someone who can (MK999?), please do!

from a few pages back, aimed at me.

eat your words paul!

great work colin. keep it up :)
the brakes look good, and they should fit.

Actually a 500kg car doing 100mph has about 60% of the kinetic energy of a 200kg bike doing 200mph. :)

that might help you :)

I suppose the bigger question is whether the amount of heat generated by the greater mass of a car would be too much for them to handle.

stock 236 solids skimmed to minimum thickness & either make caliper spacers or as previously said, cut down the pads will cut the weight, and keep the heat in the brakes. tbh you could probably machine them down further as they aren't expected to carry granny & her shopping & tow a trailer......

Colin, i think your on the money, about the larger mass of car putting to much heat into the discs.

also, another point, is if they were genius, magical answers to saving weight, surly the locost/westy boys would be all over them?

I'll bet a machined down/drilled 236mm solid won't be as low as 1.5kg though!

Off to the workshop to weigh one now........

It's true I've never seen them used on LoCaterFields.

I still haven't managed to find out what the Grasstrack cars are using for discs on the front. Some of them are definitely using bike calipers though.

it probably won't colin, but by the time you have a boss made to fit the disc to the hub face, it will weigh more. ps. it does need to be strong, as it does the majority of the braking.....
