Modern cars have a break dust shield fixed beneath the break disks. It protects against water and mud. Trad Morgans don't. Are there aftermarket parts and in what case would it make sense to add them?
Can't help with source but it would make sense to add them if you have wire wheels. They act like a fan in heavy rain throwing water onto the discs which then causes a short delay before full braking effect is acheived.
