HI I have a LR2 diesel and want to know wether we need to put electric brakes on to tow a 1.6 ton caravan? I am an owner of a new LR2 diesel and very happy so far

Iain,
My brakes are fine with a 1.5 tonne caravan, and I know people who tow heavier than mine without problems.
What I dont know is if there are different laws out where you are regarding the use of such brakes.

The UK spec is that the FL2 can tow a 750kg trailer unbraked. Above this (up to 2000kg) a braked trailer is required.

Electric brakes are (virtually) unheard of in the UK. Here we have trailers braked by means of an 'over-run' damper and cables operating brake shoes on the trailer wheels.

A quick google has found (from http://www.towingguide.com.au/ ):

According to the Australian Design Rules, all trailers over 750kgs GTM (irrespective of the towing capacity or unladen mass of the tow vehicle) must have an effective brake system fitted. All brakes must be operable from the driver's seat of the tow vehicle except for over-ride brakes.

The minimum braking system required for a trailer or caravan depends on its type and weight, as well as the weight of the tow vehicle:

•Up to 750kgs GTM: No brakes are required.
•751-2,000kgs GTM: There must be a braking system on the wheels of at least one axle and over-ride brakes are permitted. However, for caravans exceeding 1000kgs, independent brakes (electric brakes are the most common form) are strongly recommended.
