Since the modified rear brake actuation will not be ready in time we send you this specification of the brake layout for this car:-

(1) Large dia. servo fitted with 40º cams.

* (2) All other levers to the original N.Sch. except the 2.000 lever G.100958 which must be altered to 3.400 CTS.{C. Trot Salt - Carburation}

(3) The GWH.{George W. Hancock - Head Chateauroux} shoes to be set at .007 - .008.

(4) The clearances rear .500 at end 4.800 lever.
front .312 " " 3.500 lever.

At present the front equaliser levers to the rotors are to an Ex. number and these we should like to fit to 1 Per.II. The servo lever in the rear equaliser is also at the moment to an Ex. drg:

* Will you please drill this lever at 2.750 CTS.{C. Trot Salt - Carburation} so that alternative amounts of direct braking can be tried.
