How to Bleed the Master Cylinder and Brake System

This takes 2 people master cylinder is full lid back on . have assistant pump brake pedal 3 times then hold down saying "holding" then you loosen bleeder screw on right rear brake slowly air will come out then a little fluid. tighten screw and say pump it up "holding" as fluid in coming out pedal will sink "Keep pressing" repeat util clean fluid appears. check master fluid level now repeat left rear. fluid level right front fluid level left front fluid level once complte you should have a firm pedal.

they make a tool that keeps the brake proportioning valve open for bleeding them a safety feature to stop fluid in case a line breaks. but a reverse bleed can be done take a 2 ounce syringe fill with brake fluid and open bleeder screw and force fluid back to master cylinder and have someone watch to see air is coming out possibly 2 shootings per side should work.

? need to know how ? or there is brake fluid coming from the vehicles brakes ? Brake bleeding is easier to accomplish with two people. Have one person pump the brakes until there is a back pressure felt at the pedal and then have them hold pressure on the pedal. Have person number two go under the vehicle directly inside the tire where the brake line runs and "crack" the line by using a wrench to loosen it. Air will come out and once brake fluid starts to come out go ahead and tighten it back up. Repeat for all four brake lines.

RIGHT REAR, LEFT REAR, RIGHT FRONT, LEFT FRONT

check the stop light switch, this switch is two way put the key to on, if you press the brake pedal, there will be a wire that will off power while stepping on foot brake, when release, 12volts will occur, check that circuit before gping to trans troubleshooting

Easiest way. Go to any auto store, Pep Boys etc, locate the book for the year of your car and write down the wire diagram.

Check for proper operation and power at brake light switch located at the brake pedal under L/S dash. Hope this helps
