11 November 2016 - Brake system - Distribution Block Disassembly

I removed the distribution block from the brake system.  The valve in the distribution block was stuck.  I thought I would try a different way of removing the valve.  I bought some bolts so that I could plug all holes except for two, and I bought an adapter that allows the grease gun fitting to be connected to the distribution block.  It took a couple of hours of driving around town to find the correct bolts and adapter.  After putting the pieces in place, it took about 2 minutes to pop out the stuck valve!!!  Now the distribution block and valve are soaking in brake fluid.  I need to pick up some brushes to clean the distribution block bore.  And after that is done, and the rebuild kit comes in, 
 the distribution block should be as good as new.




To use a grease gun to remove the spindle valve from the distribution block, obtain the following parts;
  • four bolts that are 3/8"-24 fine thread and one 5/16" to 1/4" adapter(grease gun to distribution block port).
  • Wrap all fittings with enough teflon tape so that the bolts thread in securely.  Also when installing all fittings do not overtighten.  Only thread bolts/fittings in until they bottom out.  If the bolts/fittings are overtightened it will damage the ports.
  • Remove the "Left Front Brake" fitting on the distribution block, move it to either the "Front Master Cyl" 7/16" port or the "Rear Brakes" 7/16" port.
  • In that 3/8" Left Front Brake fitting, install one 3/8"-24 fine thread bolt.
  • In the "Front Master Cyl" 7/16" port or "Rear Brakes" 7/16" size port, install the 5/16" to 1/4" adaptor for the grease gun connection.
  • In the "Brake warning switch" port install one 3/8"-24 fine thread bolt.
  • In the "Rear Master Cyl" port install one 3/8"-24 fine thread bolt.
  • In the "Right Front Brake" port install one 3/8"-24 fine thread bolt.
  • The "Left Front Brake" port is the only open port, and will be the port that the internal valve will exit.
  • Attach the grease gun hose to the newly installed adapter on the distribution block.  Pump the grease gun a couple of times and then the internal valve should easily slide out.
