Page 3 - Master Cylinder Rebuild
P. 3
Before installing the internals coat the seals and the cylinder wall with brake fluid, this will provide a slick surface and the assembly will
slip right into place. Install the front piston then the rear piston.
Now that all the internal assemblies are back in place the snap ring needs to be installed. Hold the snap ring in place and with the pliers
ready to go push the piston in and the snap ring will snap into place. Make sure it is securely in place and move on to installing the bolt
in the front bowl.
The finished master cylinder looks factory fresh. When you’re ready to install the master cylinder on the car it is a great idea to bench
bleed the master. To bleed the master, clamp it in a vise, fill it with fluid, crack the bleeders, and with a screw driver push the piston in
several times the full length. When bleeding is finished remove the cap and connect clear hose to the bleeders draining back into the
master. Lots of air will be coming through the bleeders but at some point this will change to all fluid. Be careful not to get fluid on the
paint because the fluid will eat it away.
The black master is our rebuild and the cast lighter part is the Inline Tube reproduction. The only difference is the date code on the
bleeder side and the part number on the other side. If you are not concerned with numbers this is the way to go instead of spending a
day in the garage you can spend a day driving the car.
