<p>In a master cylinder having a reservoir mount, reservoir bayonets (28,30) or like projections extending into boss bores (20,22) of the master cylinder body (l2) are at a reduced diameter established by worst-case tolerancing, to accommodate all the tolerances along the bore centre-line plane (50) of the reservoir mount. This results in greater side-to-side clearance perpendicular to the bore centre-line than is desired in many instances, so tending to give a relatively loose fit of the reservoir (l8). To reduce this side-to-side clearance, locally raised ribs (82,84,86,88) or the like are added to the reservoir mount bayonets to better match the internal diameters of the machined body reservoir bosses provided by the boss reservoir mounting surfaces. Specifically, the clearance is reduced by locally increasing the diameter of the reservoir bayonet mounts based on worst-case tolerancing, considering only one reservoir mounting member and its associated mounting boss (l4,l6) independently of the other mounting member and its associated mounting boss.</p> |
