Completed the Steering Rack refurb today and also removed the handbrake cables from the underneath of the car. On the mr2 the handbrake does not have its own drum or separate shoes, It uses a cable to apply pressure into the calliper and effectively apply the brakes.
When the brakes are back from being refurbished I will be able to show the mechanism. In the meantime this is the refurbished steering rack, when i refurbish the item i make sure the whole thread can be used as I dont know how much adjustment will be required when refitted.
Often there is a high level of rust, so the best way to remove this and set the thread back is using the nut itself simply twist it back and forth, going a little further each time and it effectively re-cuts the track and removes the loose rust.
