Wilwood 260-18027 Brake Booster Pushrod Depth Gauge Tool

Wilwood’s new Brake Pushrod Depth Gauge Tool allows you to determine the necessary depth and length adjustment between the booster and master cylinder piston. Aluminum construction with steel hardware and magnetic mounts make the job much easier, without trial and error.

A depth gauge measuring tool to determine the necessary adjustment of the brake booster pushrod to the master cylinder piston. Setting the proper gap between the end of the power booster pushrod and the master cylinder piston is important. If the pushrod is too long, it will be difficult to bleed the rear brakes, and there will be residual pressure in the system that will cause brake drag. If the pushrod is too short, there will be excessive pedal travel and the potential of not producing enough pressure to stop safely.

Here’s how to use this tool and a feeler gauge to set the recommended gap.

 1. Loosen the set screw of the pin and place the short end of the tool labeled “Master Cylinder” firmly against the master cylinder flange.

 2. Push the pin into the master cylinder, opening until it makes contact with the piston (or piston spacer), and tighten the set screw. NOTE: Ensure the rounded end of the pin is used on the master cylinder.

 3. Place the long end of the tool labeled “Brake Booster” to the face of the brake booster, lining up the pin to the booster’s pushrod.

4. Adjust the booster’s pushrod (most are threaded and screw in/out) so the gap between the pin and booster rod is set to 0.010”-0.030”. (Be sure there is a gap). A feeler gauge between the rods provides a reasonably accurate measurement.
