Brake Drum buying guide
Why replace this part?
The brake drum provides the friction surface against which the brake shoes press to slow the vehicle. Scored, cracked, or excessively worn drums reduce braking effectiveness and generate heat and noise that accelerates shoe wear.
Signs you need a replacement
- Pulsating or grabbing rear brakes
- grinding or scraping noise from the rear when braking
- deep scoring visible on the drum friction surface
- drum thickness below minimum specification
- vibration from the rear under braking
When to replace
Measure drum diameter at each brake service. Replace when worn to minimum specification or when scoring depth exceeds 0.5mm. Always replace as an axle pair.
