Brake Shoe: Fundamentals and Basics
Notes, Warnings, and Hints
PRIOR TO REMOVING THE SHOES
-
Clean the shoes, hardware, and backing-plate thoroughly for the following reasons.
-
Initially the springs will appear black (from brake dust). The springs are actually color coded and it is very important to reinstall the springs in
the correct location.
-
The shoes and hardware will need to be cleaned to determine if an overheating condition has occurred (discolored bluish-purple).
-
Inhaling brake dust is VERY HAZARDOUS TO YOUR HEALTH.
WARNING: Do not use compressed air to clean the brake assembly.
-
Verify the Leading and Trailing shoes are installed in the correct relationship.
-
Verify the new brake components exactly match the old ones.
DURING REMOVAL
-
If there is any possibility that the shoes may reused, remove any drip pans that may be under the brake assembly and handle the shoes carefully
when removing.
NOTE: WORK ON ONE SIDE AT A TIME (unless you are very familiar with the system). The other side may then be used as a model for
reassembling.
INSTALLATION
-
Clean and lubricate the backing-plate contact pads with a high temperature silicone lubricant.
