Hi, I'm Scott from Stan's Automotive. Have you ever wanted to know more about your auto
repairs, but were afraid to ask your mechanic? We're dedicated to making sure you can drive
your vehicle for as long as possible with the least amount of expenses. This brief video
provides you with information designed to help you make the right decision about auto
repairs. On many vehicles, drum brakes are an integral
part of the braking system. When so equipped, they are typically found at the rear wheels
of your vehicle. They not only slow and stop your vehicle, but also may function as the
parking or emergency brake.
Drum brakes work on the same principal as disc brakes, but when the brakes are applied,
hydraulic pressure forces the brake shoes OUT, against the inside of the brake drum,
to create the necessary friction required to slow and stop the vehicle.
When the pressure is released, return springs pull the shoes back to their original position
allowing the wheel to turn freely.
Springs lose their resiliency, and brake shoes and drums wear out over time. We recommend
inspecting both front and rear brakes regularly: replacing brake shoes when the remaining friction
material is measured at 2 mm or less, brake drums when they exceed their maximum diameter
and brake hardware as required.
Ask your service advisor to measure the thickness of the drums every time your brakes are serviced
as worn out drums might not have enough metal left for safe braking. And, over time, brake
drums may wear unevenly causing vibration and/or noise.
A worn out brake drum may contribute to premature brake shoe wear, which leads to more frequent
shoe replacement and cost of repair.
From a safety standpoint, worn brake drums may dramatically increase the distance required
for you to stop, cause the vehicle to pull to one side, or result in loss of control
which could cause injury to you and possibly others.
Neglecting brake drum maintenance has no environmental impact.
