  Q: How to service and repair the brake master cylinder on Dodge Ram 2500 Van?

  A:

  The first step to service and repair the brake master cylinder is to remove it and then loosen the reservoir cap to pour out the fluid. After that, get rid of the pins holding the reservoir on the master cylinder using a hammer and pin punch. Vice the cylinder body down, clamping it with brass jaws and then carefully remove the reservoir from the grommets with a pry tool. Start by rocking the reservoir off to its side and pulling it free of the grommets and then remove the grommets from the cylinder body. Before installing the grommets, lubricate them with brake fluid and press them inside the cylinder with just your fingers. Place the reservoir in the grommets and rock it back and forth as you try to push it down into place. After that, insert the reservoir retaining pins into the cylinder body and bleed the system on the workbench before setting it in the vehicle.

  Q: How to Properly Bleed a Brake Master Cylinder Before Installation on Dodge Ram 2500 Van?

  A:

  The proper way to bleed a new brake master cylinder is to arrange your equipment first. Use bleed tubes and a wood dowel for working the pistons which can be made from brake line. Screw the brake master cylinder into a vise, connect the tubes to the outlet ports and see that the ends are in the reservoir. First, add some fresh brake fluid to the reservoir then push down the cushion lever with your wood dowel to release the pistons. Do not stop the process until no bubbles appear in the liquid.
