Safety & Fitment Notes

### ⚠️ CRITICAL SAFETY WARNING
Brakes are a primary safety-critical component. For your MGB, NEVER use "pattern" or unbranded cheap aftermarket discs. These can suffer from poor casting, heat warping, or even structural failure under heavy braking. Always insist on OEM, NOS, or Quality Reproductions from established British classic specialists.

Restorer's Tips


  • Wheel Bearings: While the discs are removed, inspect and consider replacing the wheel bearings (GHK1002).
  • Caliper Bridge Pipes: On 1967 models, original hard lines can become brittle over time. Inspect these for fatigue or corrosion.
  • Brake Hoses: This is an ideal time to upgrade to stainless steel braided hoses for a firmer pedal feel.
  • Wheel Type Fitment: The brake discs are the same regardless of whether the vehicle uses standard wire wheels or steel Rostyle/disc wheels; however, the hub removal process varies slightly between these two types.
