|Following the first test of JTV-1, work has been progressing to improve the brakes. This has focused on improving the pedal feel and has been succesful. However, we also modified the cable-operated handbrake system to provide `fiddle brakes` and promptly ran into a problem when testing, namely that the nearside would not fully lock. Being suitably encouraged by the improved manoeuvrability of the fiddle brakes, we progressed until we broke the transaxle at the point where we have attached the brake carrier for the drum.
This has necessitated a re-design of the brake carrier and transaxle mounts, so that all torque forces created by the application of full braking power to one or other rear wheel is not taken by the cast aluminium casing of the transaxle and is instead fed directly from the brake drum to the chassis. These brake carriers have also seen the brake drums repositioned to improve the cable run and we are looking for stronger cables.
We originally used front brake cables from a Yamaha motorcycle, but when used for the fiddle brakes, these suffered from too much stretch, and so we are looking at a thicker cable from the auto industry. This should be completed this week, but time has run out to test this and complete the other JTVs for the public launch at Eridge Park this weekend. We also thank Tecumseh UK for supplying a replacement transaxle at short notice and for their technical assistance.
Therefore the first opportunity for the public to drive the JTVs will now be at the Association of Rover Clubs National Rally at Newnham Park, near Plymouth, hosted by the Cornwall and Devon Land Rover Club.

The draft regulations have been progressing and were presented to Off Road Committee on 23 April 2002.
