How do you replace the front brake discs on a transit 350?

To replace the front brake discs on a Transit 350, begin by safely lifting the vehicle and removing the front wheels. Next, remove the caliper by unbolting it, taking care to support it to avoid straining the brake line. After removing the caliper, take off the brake pads and then unbolt the old brake disc from the hub. Finally, install the new disc, reattach the caliper and pads, and ensure everything is securely fastened before lowering the vehicle and testing the brakes.
