Description
Are the front brakes on your classic Bentley or Rolls-Royce pulling, grinding, or performing inconsistently? Worn or damaged brake drums are a common cause on these heritage models — and part number RG6780 is the correct front brake drum for late Bentley MkVI, Bentley R Type, Rolls-Royce Silver Dawn and Silver Wraith GT series models from 1950 to 1959.
The front brake drum is a critical safety component — it provides the friction surface against which the brake shoes press to slow and stop the car. On these classic Crewe-built models the braking system is a semi-hydraulic design combining hydraulic wheel cylinders with a mechanical servo, and maintaining correct drum condition is essential for safe, balanced braking performance.
This drum is manufactured to strict UK, EC and US statutory specifications and is supplied Geomet plated — a high-performance anti-corrosion coating that significantly extends service life compared to standard uncoated drums. All Prestige Parts brake drums are fully road tested and covered by comprehensive worldwide product liability insurance including the USA.
Important fitment note: This listing is for one front brake drum. Two are required per vehicle — one for each front wheel. We strongly recommend ordering two at the same time to ensure both front drums are replaced together, which is essential for safe, balanced braking performance. Fitting one new drum against a worn drum will result in uneven braking and pulling to one side. fitting a single new drum will result in uneven braking and pulling to one side. Always replace both front drums at the same time, and inspect brake shoes, wheel cylinders and hardware for wear while the drums are removed.
Signs your brake drums need replacing: Grinding or scraping noise when braking, brake pedal pulsation or vibration, vehicle pulling to one side under braking, reduced braking effectiveness, visible scoring or deep grooves on the drum surface, or drums that have been machined beyond the minimum thickness specification.
Fitment: Bentley MkVI — late models 1950–1952 (chassis B1GT to B301PU), Bentley R Type — 1952–1955 (chassis B2RT to B250ZY), Rolls-Royce Silver Dawn — 1950–1955 (chassis SCA1 to SVJ133), Rolls-Royce Silver Wraith — 1951–1959 (chassis WME1 to HLW52).
