[TR4A Handbrake]

I know this is a very old post, but I wanted to endorse the Richard M modification to resolve the poor handbrake issue on the TR4A.

I tried all the earlier recommendations (checking the cables/adjustment etc) with only marginal improvement, but re-drilling the hole in the handbrake lever, made a significant improvement. Well worth the relatively little effort.

[TR4A Handbrake]

As this thread has been going on for some time I'm probably a bit late to throw in my bob's worth but here goes anyway.

After struggling with this problem for a time I was advised of a quick, easy and more to the point, effective cure by Keith from the North London chapter. It simply requires removal of the handbrake lever and re-drilling the hole in the lever where the compensator link pivots nearer to the main fulcrum. thus, at a stroke the leverage on the cable is increased hugely. The operation arc of the handbrake is increased proportionally but as long as the brakes are kept in reasonable adjustment it all works fine. A good yank on the lever and I can lock the rears on my 4A. Brill
