What you will gain from this guide
- Oil on brakes reduces stopping performance
- Seal failure often follows bearing wear

Diagnosis steps
- Inspect for oil streaks inside wheel and on drum
- Check bearing play when hub is warm
- Identify seal part number before ordering
Repair tips
- Replace bearings if pitted or noisy
- Clean brake surfaces after seal work
