How often should drum brake pads be replaced?
2 Answers
Drum brake pads should generally be replaced every 25,000 to 30,000 kilometers. Other situations that require brake pad replacement include: 1. When the brake pad thickness is reduced to only one-third of its original thickness; 2. When abnormal noises occur during light braking; 3. When the braking response becomes sluggish and braking force weakens. Brake pads, also known as automotive brake linings, refer to the friction material fixed on the brake drum or brake disc that rotates with the wheel. The method for replacing automotive brake pads is: 1. Lift the vehicle and remove the tire; 2. Unscrew the fixing screws on the brake caliper and remove the brake caliper; 3. Remove the old brake pads and push back the brake caliper piston; 4. Clean the installation bracket of the brake disc and install the new brake pads.
I found there's no fixed standard for drum brake pad replacement intervals, mainly depending on driving habits and vehicle condition. For urban commuters like me who face daily traffic jams and frequent braking, inspection or replacement is needed every 30,000 to 40,000 kilometers. I remember last year when my brakes made abnormal noises, the mechanic said the thickness was down to just 2mm and replacement was mandatory. Safety is too crucial - brake failure could easily lead to rear-end collisions. Extra caution is needed during rainy slippery conditions as wear accelerates faster. During routine maintenance, always check brake pad thickness - maintain at least 3mm minimum, never compromise safety to save money. If unsure, visit authorized dealerships for professional inspection to prevent bigger hazards.
