Has anyone created a type of modification to keep the heat out of their rear drum brakes? Firm feel sells carbon-ceramic pads, I have heard about drilling holes in the backing, and running air ducts to throw some lower temp air at them. Just wondering who has tried (successful or not) what and how it worked out. I do not want to swap out to a disc in the back for reasons that would piss off the mopar society... Lol
 
The front brakes are the ones that can glow and boil the brake fluid. The rears almost never give problems. I have had to replace the axle vent hose due to pushing fluid out. I have only run good quality semi-metallic front pads.
 
Fronts are going to be replaced with disc, but the rears are going to be hooked up to a hydraulic handbrake, so they will be getting alot more than the normal duty.
 
You could always plumb in water nozzles to a washer pump and cool the drums with a water mist
 
If you pump air into the back plate, it will have the shoes between it and the drums. The main exhaust for heat from drums is form the outer surface; you would be better off to direct the air between the druam and wheel.

So what type of racing are you doing if I may ask?
 
Up grade to a rear disc if you're drifting .. no drum will like 3 weel braking for Berry long

I had a similar mod in high school ever I would spray the rear tires with used motor oil and do burn outs till the tires blew out and it is assume on a 4x4
 
Metallic shoes, like the police cars had, would let you have good brakes even if they were glowing.
 
Use of 11" finned drums will help and so will drilling holes in the backing plates but that will also limit effectiveness in wet weather. Used to run drums and 10.60's 1/4 mile in a 3200 lb car at the old Houston International track and could take the 1st turn off if needed.
