Reconditioning caliper/master cylinder

[bigdavevw]

Hi guys,
I,m building an electric go kart as part of a college project.

I,m looking to refresh the braking system with new seals, pads, hose and hose fittings.

I dont know much about the brakes. I was told the frame is a Zip kart, and that the brakes are original.

So is anyone able to tell from the pics if the bores are ok?
Where is a good place to buy the seals and o rings from?
What diameter hose do i need and what size are the connectors?

Any help would be great

Dave

I have no idea about those brakes. But it looks simple enough that replacing those o-rings would be a start getting them working.
