Manco Dingo Brakes

[Craig.andrews1818]

Hey Guys - The last thing I need to fix on my updated kart are the brakes. See attached images. Two things to consider. One side needs new pads. I read somewhere that you should just by all new calipers, which seemed odd. How are the new pads attached to the calipers? It looked like it was some kind of adhesive keeping the pads on. One pad fell off.

In general is there a way to run brake lines directly to the brake arm and to the pedal? With the current setup you can see the arms attach to the black bar that then goes to the pedal. I am new to this so unclear how I get a brake line on each arm directly that both end up at the pedal.

Thanks for your help!

Just replace the pads and rebuild the calipers. They used to make kits for this, look around. Just leave the rods alone and lube the pivots real good. You can’t make them better than the factory.

Actually you can make them a little better than the factory. It's a mechanical disc brake, and at its very best it will never be better than O K. Once you get the pads straightened out, on the bottom of the caliper where the rod that does the pulling connects, build a extension for it. It will give more leverage ( more pulling power ).
I have the same brake setup on one of my karts. It helped enough that I am recommending it. I used a flat plate of steel ( 3/16" X 1" X 4" ). Drilled two holes to bolt it to the piece that comes out of the caliper. Drilled a hole at the lowest point onto which the rod connects. Took about a half hour to make. Improved stopping power from really poor, to at least acceptable.

They do still make kits. Go Power Sports sells them, and or the whole caliper.

Can you share a few pics of the setup you provided?

I'll try in the morning. Kart is on a trailer, and I sleep late. About noon California time I should be able to.

To be clear - disc brake "pads" consist of a metal back plate with a friction material bonded to it. When you replace them, you replace each pad as a unit - you don't glue new friction material to the old backing plate. As to new calipers - I guess that depends on your mechanical ability and budget. While there isn't much labor in servicing mechanical calipers and installing new pads, if you shop around you can generally find new complete calipers ready to go that look new for not much more than the cost of new pads that may not fit right.

What do the pads stick to the caliper with on a new install of pads?

Normally you would be right. But in the case of the manual calipers you have to glue them.

Here are some pictures of the extension I built for my caliper.

The dark piece is the caliper pull section. The shiny piece is the extension. Not very elabrit. Just simple rule of geometry. Longer fulcrum equals more force.

I never bought new pads for mine. Might have been part of the problem of poor stopping power, but they seemed plenty thick when I acquired the kart. On the side that moves, I think it would fall out if I were to un-adjust it too much. I keep it just short of dragging on the disc, so it has nowhere to go. Hope this helps you out some. As mentioned by Willie1 earlier today, the last time I looked on the GPS website, I think the new caliper complete was $30.

I guess I never paid that much attention to them. That probably does make sense thought - 1 part number covers a lot of different backing pad shapes.
