For those that think rear brakes do very little,
Ask yourself, If that is true, Why are cars made with REAR Brakes?
The Tiger in my avatar has Stock Rear Drum Brakes!
HOWEVER it does NOT have stock rear brake shoes!
Brake Friction material is EVERYTHING!
Regardless of Brake type, the correct Friction material is Key.
As a disclaimer, I have not kept up with Brake Tech.
The rear brake shoes (material) have been the same for over 20 years!
AND with the higher temp working shoes, Rear brake Ventilation
WAS absolutely Necessary, to keep the brake Drums from Cracking!
I have been using Carbotech Kelated Metallic shoes.
If you are serious about your Brakes, get the right lining material first.
IF that does not work out, change your brakes.
However, consider the Cost of the Better Friction pads before settling on
a type of caliper.
Prices can very a BUNCH for the same Friction material for different cars.
