or the older type use steel rod
Ah right, I know how rear brakes on a car work. I was thinking they worked in a similar way.
I'll do a search on over run brakes and the steel rod type.
I take it you specific wheels/hubs to attach to trailer suspension arms. Ive seen them advertised on fleabay, but wasnt sure if you had to use the same make hubs/etc
thanks

The coupling hitch slides inside the mounting which atttaches to the trailer frame, the end of that sliding element pushes against a lever which is coupled to a cable or rod which pulls on the brakes with a pressure proportionate to the force that is exerted on the coupling hitch by the tow vehicle braking.
There are also hydraulic versions for heavier trailers, but using the same principal.

there are lots of different makes and typre available google towsure they sell braked units there will probably be somewhere cheaper but it will give you an idea

There are different rules for new trailers and repairs/replacement on old trailers.
New trailers require damped couplings and brakes that don't apply when reversing.
It will work out simpler and cheaper to repair an old trailer.
You also need to provide compensation, so that both brakes apply evenly. It's a lot easier to do this with cable brakes.

thanks for the advice everyone, I've looked into find an older trailer (over the past couple of months) They either come up as total rot box's which everything needs replacing on them, or its dreamers who think, they are worth more than gold (well not quite,lol)
I'll keep looking, just ive found all the parts second hand/steel new, local to me for very cheap prices, but I cant get the hubs/wheels cheap. So its kyboshed that idea!
thanks again

A bit of background reading for you - some information which isn't as easily available as it should be.
I built myself a trailer recently, and asked my dad (long serving traffic copper/landy fanatic/car enthusiast) about it. He sent me this, which is taken directly from the police guidance, wrt. brakes and reflectors, etc.
Hopefully, it will answer some legal questions?
Reflectors:
Max 400mm in, from the outside edges
Separation: 600 mm, if the overall width of the vehicle is less than 1300 mm, 400 mm or if less than 800 mm, 300 mm.
2(c) VERTICAL:
(i) Maximum height above the ground where one or two rear reflectors are required to be fitted:
(A) 900 mm or, if the structure of the vehicle makes this impracticable, 1500 mm.
Requirement for 'parking brake':
Regulation 89 of the Road Vehicles (Construction and Use) Regulations 1986 provides for the leaving of
trailers at rest.
89. No person in charge of a motor vehicle, or trailer drawn thereby, shall cause or permit such trailer to stand on a road when detached from the drawing vehicle unless one at least of the wheels of the trailer is (or, in the case of a track-laying trailer, its track are) prevented from revolving by the setting of a parking brake or the use of a chain, chock or other efficient device.
And: The parking brake shall be so designed and constructed that:
(b) in the case of a trailer, its brakes can be applied and released by a person standing on the ground by a means of operation fitted to the trailer; and
(c) in either case, its braking force, when the vehicle is not being driven or is left unattended (and in the case of a trailer, whether the braking force is applied by the driver using the service brakes of the drawing vehicle or by a person standing on the ground in the manner indicated in sub-paragraph (b)) above can at all times be maintained in operation by direct mechanical action without the intervention of any hydraulic, electric or pneumatic device and, when so maintained, can hold the vehicle stationary on a gradient of at least 16 percent without the assistance of stored energy.
As for the 'break-away' system:
Regulation 86A of the Road Vehicles (Construction and Use) Regulations 1986 provides for the use of secondary coupling on trailers.
86A (1) No person shall use or cause or permit to be used on a road a motor vehicle drawing one trailer if the trailer:
(a)
(b) is not fitted with a device which is designed to stop the trailer automatically in the event of the separation of the main coupling while the trailer is in motion,
unless the requirements of paragraph (2) are met in relation to the motor vehicle and trailer.
(2) The requirements of this paragraph, in relation to a motor vehicle drawing a trailer, are that a secondary coupling is attached to the motor vehicle and trailer in such a way that, in the event of the separation of the main coupling while the trailer is in motion:
(a) the drawbar of the trailer would be prevented from touching the ground; and
(b) there would be some residual steering of the trailer.
(3) No person shall use or cause or permit to be used on a road a motor vehicle drawing one trailer if:
(a)
(b) the trailer is fitted with a device which is designed to stop the trailer in the event of the separation of the main coupling while the trailer is in motion;
(c) designed to stop the trailer automatically in the event of separation of the main coupling while the trailer is in motion; and
(d) the trailer is not also fitted with a device which is designed to stop the trailer automatically in those circumstances in the absence of such secondary coupling,
unless the requirements of paragraph (4) are met in relation to the motor vehicle and trailer.
(4) The requirements of this paragraph, in relation to a motor vehicle drawing a trailer, are that the secondary coupling is attached to the motor vehicle and trailer in such a way that, in the event of the separation of the main coupling while the trailer is in motion, the device of the kind referred to in paragraph (3)(b) and (c) fitted to the trailer would stop the trailer.

Bit like Triggers broom then?
Still if you got it cheap enough (free) and it gets around the regs.
Sounds a bit like the Tax exempt Land Rovers with coiler chassis, Tdi engines and defender bodies.

I was only wanting to build a small trailer for a mini, i had previously sourced all the parts locally and better still (cheaply) but the breaking system was my biggest down fall.
I would convert a caravan chassis, but they are few and far between.
thanks, Ill save my pocket money up for something better (it goes against my better judgement...throwing money away)

You can sometimes pick up old road trailers from boatyards which need too much work to make them commercially repairable. Even if you change the chassis shape, it's classified as a repaired road trailer. Sometimes boat clubs are glad to get rid of old dead ones left by members to rot away, and will sell for the price of scrap metal, or not much more.
