Obtain a ' one man bleeded kit' at a parts store. There will be directions with this to get the job done. Also get a fresh container of brake fluid. You will also need the correct wrench to loosen the hydraulic lines on the master cylinder.
The master cylinder can be easily replaced with a new unit, by disconnecting the brake lines, capping off the brake lines, detaching the old master cylinder by unscrewing two bolts.You must bench bleed the new unit before installing. Then reverse the above. Protect surfaces from brake fluid spillage.
Disconnect electrical connection Remove and cover brake lines Remove mounting bolts Pull Master cylinder off power booster Install in reverse order, but remember to BENCH BLEED master cylinder prior to installing
Fill master cylinder and open the bleeder valve on the caliper and let it drip while you have a coffee break. Re-tighten and do other side. re=fill master cylinder
There is no procedure. The only components that need to be bled (depending on work performed) are the master cylinder, wheel cylinders and calipers.
First, make sure the master cylinder is filled with brake fluid. If it is low, there may be a leak somewhere in the brake lines or a brake cylinder. If the master cylinder is bad, you can normally pump the brakes up, but the pedal will slowly sink to the floor again. The master cylinder needs to be replaced or repaired.

Always start at the wheel that is the farthest away from the master cylinder and work toward it. Typically it would be the passenger side rear, driver side rear, passenger side front and driver side front. Use a bleed kit to make sure all the air bubbles are out before moving to the next cylinder. Also make sure the master cylinder does not go dry during this process so air does not get back into the system.
When you press and hold the brake pedal it will slowly move to the floor. It can also have a catastrophic failure and go straight to the floor with no stopping ability at all. If you hold the brake pedal down and it slowly moves to the floor any at all, replace the master cylinder.
