Hi,
Can anyone tell me what override brakes are on a trailer. I have hydraulic disc brakes on a camper are these the same thing or different?

Override breaks are activated by the hitch either compressing a break cylinder or acting on a cable system, It is a manual system as opposed to an electrical one.
I would think if you have discs it would not be override.

I have a
Kimberley Kamper with override brakes (as described by Notso, below) and the brakes are discs not drums.

Easy to check it mate.
If they are over ride brakes there will be a small resevoir of brake fluid just back from the coupling on the trailer draw bar. You will also see a section of the coupling just beyond the tow ball or whatever connects you to the motor vehicle that slides back and
forth as you apply the brakes. This actuates the master cylinder and applies hydraulic pressure to the brake cylinders on your trailer
wheels

I Agree, but my one is cable not hydraulic. A very good word picture of the set up.

They don't have to be hydraulic - some can be mechanical with a cable from the overide mechanism to the brakes

Our trailer sailor trailer (!!) had overrider disc brakes working off a cylinder at the back of the trailer coupling.
More common is the cable and drum overrider brakes working off the handbrake lever at the back of the trailer coupling.

Their should be a over centre latch on the coupling to engage for reversing to lock brakes out. over ride only ever work when in difficulties.

Yes, for these brakes to work the trailer has to push the car. This can be detrimental when the trailer approaches the weight of the towing vehicle and you brake on wet roads.
Override brakes also only hold when you are stopped facing downhill, they do nothing if you are stopped facing uphill and the car's handbrake might not be up to holding the car and trailer.
I much prefer the electric brakes where the trailer brakes can be set to come on slightly before the towing vehicle's brakes.
