Brake rotor backing plates

[Jack21]

Fine tuning and deglitching. Driving in the rain. The driver stays dry, the engine stays dry, but the brakes get wet. I have to ride them a little to dry them out to make sure the car will stop. Fronts are MII with Grenada 11" rotors. Rears are 10" rotors on 8.8 solid axle. Pretty sure these are the stock brakes from '87 - '89 T-bird Turbo coupe. No backing plates on front or rear. Somehow, I figured there had to be a reason all factory cars have them. So what is the school solution for backing plates so the rotors don't get splashed when it's raining?

Jack, I may be all wet here but I think the backing plates were more for keeping the dirt and grease from getting on the brake pads from the ball joints, etc. I don't think they would deflect enough water to make a difference. I don't know of any aftermarket plates that will work with the 11" fronts. I know the design of the disc brake system was to eliminate part of the problem with brakes getting wet and not working such as in a drum system. I'm sure if enough water gets to any brake it will fade.

Jack,
Like Don says, used to prevent stones mostly from getting into the brake system. The backing plates are so full of holes, now way would these keep the brakes dry!
