Proportioning Block troubles

How does one re-center the shuttle piston? Ive already removed it from the car

Popular is using air or grease gun. There are some threads here somewhere recently discussing solutions. Maybe in the Maintenance section. Try not using harder than brass projectiles to poke it into place. Good time to disassemble and inspect seals.

After you get the valve centered use one of these.

WCCC sells the rebuild kits. I usually just pull the shaft out with needle nose pliers. Had to use heat once. I’ve never tried the air or grease methods.

Make sure when you rebuild to fully seat the outermost oring or it will leak fluid

Used the small needle nose approach- worked perfectly- all centered now with centering tool in place- THANKS ALL!
