I'm being pestered into making a decent go-kart for the kids. The previous attempt that we built during a bathroom refurb was great fun but it
had no brakes:

so this time I want to provide some stopping power, but on a budget. I think the way to go is to use disc brakes and calipers off a push bike. So,
my questions are:
(1) Are front and back brakes on bikes the same? I see them advertised as separate items so what's the difference between them?
(2) Where can I get some new or used calipers and discs for next to nothing? eBay is OK but all the second hand stuff seems to be Shimano or whatever
and I don't care about brand names or weight. I can get new calipers for £3.99 + £2.50 p+p, off eBay which seems reasonable.
For simplicity and cost I'm thinking cable operation rather than hydraulic.
Does this sound like a good idea? Maybe someone on here has got a couple of scrap brakes they would like to swap for ££? I'm only going to
brake one axle so I'm after 2 calipers and 2 discs.
IIRC as far as 1) goes, the same caliper will fit front and rear, but the rear needs a 20mm smaller disc (165R 185F is pretty standard) at least with
the IS tabs.
I'd beware anything costing £7 if you actually want them to work.
You only need one disc
My pads alone are £20 per pair on my mountain bike!! They generally differ in the length of the cable / hose, as well as often in size.
IMHO... get a brake assembly from a moped..... would be cheaper and much more chunky...
I have a set of 4 pot single piece alloy callipers on the front of my mountain bike complete with floating disk rotor... they were NOT cheap.. but
will stop on a halfpence from 40mph (assuming you can stay on the bike!)

We picked up some el cheapo Chinese made wheels with bearings and pneumatic tyres at Stoneleigh for a few quid apiece. The wheels will be on 16mm stub axles so I thought I'd better go for two brakes, ideally at the front.
This was the caliper I had in mind:
