| - 2 - Cont'd.{John DeLooze - Company Secretary} satisfactory in view of the relatively low performance. 5. Holes for Adjustment. It was suggested that two holes were more likely to be in balance than one. This was carried unanimously. 6. Thickness of Lining. The question was raised as to what thickness of lining the range of adjustment provided. It was agreed that Lockheed's would let us know. There was no basic objection raised by Mr. Parnell to lining up to .250 thick. 7. Road Tests of 2 Leading Shoe Brakes. Mr. Parnell said that Mr. Gates' car had been fitted up exactly as we are proposing to fit the Rippletto and that he would arrange to let us try it during his next visit. 8. Division of Manufacture. It was agreed that eventually, in production, Lockheed's would make everything up to and including the water excluder. Mr. Parnell thought that the water excluder might add slightly to the cost of the brake. 9. Location of carrier plates. The carrier plate will be located by fitting bolts. The necessity for accuracy of workmanship was emphasized. The possibility of having the same carrier plate on the back as well as the front axle with this brake was raised as a potential economy. Bastow pointed out that this meant modification to the pivot design. Rm.{William Robotham - Chief Engineer} suggested that the new pivot design for the senior range might also be adapted to take the standard Lockheed brake shoes. Mr. Parnell said there would not be any difficulty about Lockheed's supplying brake shoes for 12" drums 2¼" wide. - Continued - | ||
