Adjustment (Diamante)
1) Start engine and depress the brake pedal at least two
times then switch the engine off.
2) Remove the master cylinder from the brake booster making
sure the push rod is not disturbed and the brake pedal is not
depressed after master cylinder removal.

thickness of the block gauge and add .366" (9.3 mm) to the gauge
thickness and set the caliper to this dimension. See Fig. 4.

NOTE: This measurement is taken on the radial face of the push
rod, .085" (2.15 mm) from the center of the radial face.
This adjusting procedure MUST be done with 18-22 in. Hg
(62-73 kPa) of vacuum applied to the brake booster.
