I used to regularly use them on MKIII Cortina'sAt one time you used to be able to get abrasive padsThe idea was put them in to clean up a disc for a few hundred miles and then revert back to normal pads.
no but does drive loaded and does lots of miles. I find a lot of vehicles have the brake bios set wrongly and the fronts are doing most of the work, a lot of transits etc have load sensing valve that are not adjusted correctly meaning 80/90% or more braking is done on the front,LR discoveries are terrible for it they have pressure limiting valve and under light braking nothing is done at the rear hence the rusty disc syndrome3mm in a month whats he doing towing a mini digger with little brakes on the trailer and going way too fast up and down welsh hills in a Mankini
not when towing, or loaded it isnt, because if you look at commercials for instance the braking is done more by the rear, with the the aid of a load sensing valve, what happens with early discoveries is that, if you brake hard, and the front wheels lock, you then lose the actual braking effect, but more crucially the steering as well, but because you have lost overall braking effect, the trailer overrun brakes then reduce effect and you have this horrible situation of an uncontrolled lock up .
