Adjusting the push rod clearance at C or no clearance at B or C

WARNING: This page is about a different car, the 2005 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The threads of the push rod are specially designed so that the bolt becomes harder to turn past a certain point. This is to prevent the bolt from coming loose. Turn the bolt only within this range when adjusting.

Measure and record height D1 of the gauge rod.
Turn the adjusting nut until the SST body sets squarely on the master cylinder. (Turn only enough for the body to touch.)

Measure and record height D2 of the gauge rod.

Subtract D1 from D2 and add 0.1-0.4 mm {0.004-0.016 in} . Using the SST , turn the nut to shorten the power booster push rod an amount equal to the sum.
