Adjusting the push rod clearance at B

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.

Push lightly on the end of the SST gauge rod, and measure the clearance between the adjusting nut and the SST body.

Using the SST , turn the nut to lengthen the power booster push rod an amount equal to the sum subtracting 0.1-0.4 mm {0.004-0.016 in} from the clearance measured at B.
