EXPANDING LOCK

ACCESSORY KIT FOR HANDBRAKE SHOES

16 references; covering 40 different handbrake shoes (BMW, Mercedes-Benz …)

Functionality:

• Adjusts to the wear of the shoes to ensure the right friction and hold power
• Locks the shoes in “hold” position to secure the vehicle from unintended rolling

Why changing and not cleaning:

• Material wear of the lock could lead to reduced functionality; rolling of the car
• Due to wear of the part adjuster nut might not adjust correctly
• Cleaning of the parts for re-use might lead to corrosion; handbrake can get stuck

Car manufacturers like BMW recommend replacing the expanding locks
every 48 months (if not worn earlier) and with every change of handbrake shoes.
