the master cyl must be filled and bled before install.after installing new bled master cyl,bleed all calipers.once you are sure there is no air left in system then you will need a scan tool to perform a abs service bleed.if you do perform the abs service bleed with a scan tool the brake pedal will be soft and start to fade.

i do agree with the haynes manual.
First off, pb blaster is your best friend for brake line bolts. You want to **** as much of the brake fluid out of the resivour as you can, Then you need to get the brake lines off the master cylinder that is on there. make sure you use the right size flare nut wrench when you are taking the lines off. rounding off brake line bolts is not fun, trust me. once the lines are off, ( turn counter clockwise) Just make sure you have a towel to put under the brake lines. for excess fluid. then with a ratchet, and extension, and socket you need to take the master off the brake booster. Also disconnect any electrical connectors and keep them clear ofthe brake fluid. When you have the 2 bolts out of the brake booster, the master should pull out and then your ready to work on installing the new one. when you get a new ,master, you can either bench bleed it, or if you want to, you can also install the new one, line up the hole in the brake booster, put the 2 bolts back on, then you need to bleed the master. Most come with instructions.
In simple terms, by just looking at it, you can figure out how to do the master cylinder, but to be safe, get a repair manual.

There is a special tool required to bleed the brakes, it plugs into the ABS hydraulic control under the hood and holds the ABS valves open to remove the trapped air during bleeding, u will need to have the dealer bleed the brakes, they are most likely the only ones that will have this special too, but u can try an outside shop, I am sure Snap on tools makes this tool in the aftermarket tool catagory..

Hello, Some of these systems require a Power Brake Bleeder to clear the lines of air. The bleed routine is to go from the farthest to the closest axle on bleeding. Do passengers rear, drivers rear, passengers front, then finally drivers front.
You may have a problem with the valving in the ABS unit. You would need line pressure gauges to measure what is going on inside the unit. You may be able to rent a Power Bleeder or get one free with a deposit at Autozone, Oreillys, or Advance to name a few.
The ABS can also be scanned with the proper scanner. You may be able to rent a tool for this or again check with the Autoparts stores.
