• Q: How to Service and Repair the Brake Master Cylinder on 2005 Dodge Ram 2500?

  A: Apart from Hydroboost, depress the brake pedal five times to exhaust the vacuum in the booster, empty the reservoir completely, cut the electrical wire to the warning system and keep a towel or rag close to the booster's outlet port. After that, unplug the brake lines from the brake master cylinder, both mounting nuts and direct the brake master cylinder and reservoir away from the booster, making sure the assembly is standing upright in front of it so it does not hit its output rod. When working with Hydroboost, take out the brake lines from the brake master cylinder, remove the connector to the low fluid sensor, unscrew the mounting nuts on the brake master cylinder and gently remove the brake master cylinder forward to protect its internal output rod. Install all except Hydroboost systems so that the output rod's position is good and it is held in place by an output rod retaining ring before it enters the brake master cylinder plunger sleeve. Always check for a vacuum seal at the shoulder of the brake master cylinder flange. Mount the brake master cylinder where the service manual says to, so the plunger stays in position over the output rod, put on new nuts and then tighten these to 25 Nm, fix the brakes lines in place and tighten them to 19 Nm, connect the low fluid level switch cable and finish by filling and bleeding the base brake system. When using Hydroboost, fit the brake master cylinder to the booster studs, add new nuts and tighten them to 25 Nm, fit the brake lines snugly and tighten them to 19 Nm, fasten the low fluid level switch connector and use your bleeding tools to fill and clean the basic brake reservoir.
