-9- the car is standing with the engine running, also they can be heard in the driving seat when travelling. With the spherical mounting, less end clearance should be possible. The staybrite finish is in good condition. FRONT AXLE & BRAKES to LOP G.53576 - G.L.375. Incorporating:- (1) Thicker brake shoes G.54145 A.M.R.2 .375 thick. (2) G.54160 Brake Drum (Damping Spring fitting direct on Drum). (3) S.S.3141 Centralised Lubrication including Non-return Valve and Filter to Arrgt.G.54299. The axle shows no flaws and is in good condition. The Centralised lubrication scheme is operating satisfactory. The Brake shafts and toggles have been amply oiled. The front brakes lined with A.M.R.2. material are more efficient and at the present mileage have been almost free from squeaks. A slight squeak occasionally having been heard. A feature which affects this is, water enters the drum during the washing process which causes the drum braking face to rust up in spots. This makes the brakes squeak upon the first two or three applications. The A.M.R.2 material is giving very good results in life, no adjustment being necessary at this mileage. The brake drums do not show any scoring and are in a smooth condition. REAR BRAKES to LOP G.53594 G.L.374 Incorporating Thicker Brake Shoes G.54143/4 A.M.R.2 material .375 thick. Hand and foot brakes. The rear brakes are more efficient when hot with the A.M.R.2 material than with the Ferodo material. The drums do not show any scoring, the surface remaining smooth. There have been groans from the brakes. These are more definite after the car has been washed and stood overnight. Water enters the drums and rusts them up similiar to the front. They are pratically free from groans after being warmed up. The shoes show very little wear, no adjustment being necessary at this mileage. FRONT SHOCK DAMPERS to LOP F.55944. (1) F.57380 Intermediate Lever (S/ZIX), replaces F.56357 (S/Z). (2) Scheme 1269 (fig. 2) Spring Loaded Connecting Link. (3) Hole in H.P. Valve deleted. (4) Air vent to all Valve Lift restricted to .010" Loads set:- Low Pressure 60 lbs. High pressure 75 lbs. The front dampers have been free from knocks with the above setting. The O.S. damper poundage had remained consistent. The N.S. damper had lost practically all its poundage. This was | ||
