The British Historic Kart Club

I have a 70's Zip Kart with what I believe is the original caliper. I'll get some photo's of the caliper, but for the time being the Kart can be seen here viewtopic.php?f=150&t=2682

The Caliper is similar to that of the rather splendid Zip restored by Silverstripes viewtopic.php?f=21&t=2688

My caliper differs in that it only has one pipe feeding hydraulic fluid, unlike the two pipes on Silverstripes Kart.

I have no pads with the caliper so I assume that it will take these viewtopic.php?f=195&t=2667

I also figure that the pad release mechanism is a mechanical, bolt through sleeve, spring and caliper body into back of brake pad. However, there are some additional bolts that screw into and through the caliper body that I figure could exist to adjust the gap between pad and disc as the pad wears by providing and adjustable pad stop.

Have I figured it right cos I don't have the benefit of having raced when I was young, and my lads Tonykart self adjusting caliper makes the Zip item look like something I might have knocked up in a metalwork lesson at school

If I am right, any idea of length of bolts, springs and sleeves and which ones might do the job

I think you have it there including the metal work class !!

The bolts which hold the pads in place are 35mm long and are M6. The sleeves are just tube and are 25mm long. But of course I have the 2 part caliper.

Any Help

I've just restored my Mirage which appears to have the same set-up as your own Kart. It's a bit of a nightmare, as there are several patterns of pad used (3x so I was told). Adrian at BRT was fantastic, and was able to supply pads and full repair kits for the caliper and master also. Best to send him your old pads I suggest.

Hope this helps?
