Because the Netherlands has some very stupid rules about towing capacity we are only allowed to tow 5000lb with our D250. If we want to tow 7716lb (maximum with mechanical brakes on the trailer) we needed to do a park brake test which was to see if the parking brake can brake 5200lb/ft on the brake test rollers. We only came to 4050ft/lb so it failed.
Now I want to see if I can uprgrade the rear brakes so that it will pass. I might have some oil in the drums because of the leaking seals so I will replace those first.
Next would be new brake shoes, wheel cilinder and cables.
What is the best brake shoes that you can buy? And i see 2,5" and 3" wide shoes, which so I need?
