			Brake cylinder bore and stroke.
		
		
				
					
					
				
				
		
			
				
					Does anybody know what the bore and stroke of the brake master cylinder is? I am interested in the CB (compression barrel, or the "big nut") master cylinder, as used on a IIa 109".
Aaron.

					The  LWB IIA Girling CB:  bore = 1.0 inches, stroke =1.5 inches, pushrod free movement = 1/8th inch. But a lot of IIa's I think (like mine) would have a later PBR unit with servo fitted.

					So that would give a cid of 1.18. I am figuring out which VH Hydrobooster to fit.

					Furthur to this can someone give me the bore and stroke of a Discovery 1 brake master cylinder (1997 model). I have fitted disc brakes to my series 2a from a discovery and am trying to work out which master cylinder I would like to run.
