Brake Booster Push Rod - Probe
NOTE:
Some boosters use factory adjusted or nonadjustable push rods. Do not attempt to adjust this type of push rod.
- Use Depth Gauge T87C-2500-A. If Depth Gauge is not available, a pencil may be used. Insert pencil in push rod socket and mark it with hack saw. Using ruler, measure length of pencil to hack saw mark. Using ruler, measure how far master cylinder push rod protrudes out of booster. Measure master cylinder boss with ruler.
- Subtract length of boss from length of pencil. The difference in length between master cylinder push rod and pencil length to hack saw mark is equal to push rod clearance. Adjust push rod length to get correct clearance. It should be .025" (1mm) shorter than push rod socket.
