How to Replace a Garage Door Bottom Bracket
Garage door bottom brackets are critical components that connect the cables and rollers to the door. In regions like Canada, winter weather often causes brackets to rust due to water and salt exposure. Rusted brackets can loosen screws and bolts, increasing the risk of a broken garage door cable or misaligned roller.
Safety First
Warning: Replacing bottom brackets involves high-tension springs and moving parts. Do not attempt repairs unless you have proper tools, experience, and safety equipment.
Steps to Replace a Broken Garage Door Bottom Bracket
Secure the spring shaft – Use a locking plier to prevent the shaft from rotating. Alternatively, fully release spring tension by unwinding all springs.
Release the cable – Unscrew the cable drum and free the cable if it’s not already loose.
Remove the rusted bottom bracket – Unscrew the bracket and remove it from the garage door track. Remove the cable and roller as well.
Install the new bracket – Place the replacement bottom bracket on the garage door. Reinstall the cable and roller if they are in good condition.
Fasten screws and nuts – Secure the bracket firmly to the door track.
Reconnect the cable – Attach the cable head back to the cable drum.
Wind the spring – Rewind the garage door spring carefully.
Test and adjust balance – Check the garage door for smooth operation and adjust the spring to ensure proper balance.
Congratulations! Your garage door bottom bracket replacement is now complete.
