There is alot written about the AK hand brake setup not being strong enough to pass IVA\MOT and scoring over 18%.

Time will tell when I get to IVA stage, (edit i got nearly 30%) however at the moment it seems damn good. I spent alot of time bedding the brake shoes and adjusting. I think my next build however will probably use an electronic hand brake to ensure good power and less faff installing the hand brake.
