| HS{Lord Ernest Hives - Chair}/GML.10/KW.6.2.34. BRAKES - STANDARD FERODO. 4-B-IV. Tests have been carried out after pouring water on to the brakes to ascertain their efficiency. There was approximately 20% efficiency for the first three brakings; fourth and fifth applications the rear brakes had regained 75% efficiency; sixth application there was 80% all round efficiency; 7th the brakes were back to normal. In the first three applications, although the efficiency of the brakes was poor it was evenly distributed, and free from any diving, shuddering or such ill effects. | ||
