Best way is to"bench bleed"
Remove and secure in a vise (by the flange and not the body)
Connect 2 flexible lines to the outlet of the cylinder and run them into the reservoir
Use a dowel or similar tool to operate
Operate slowly until no bubbles are observed in reservoir
Take your time -may take 5-10 minutes to fully eliminate all air
Remove hydraulic fluid line from slave cylinder (you may need to use a flared end wrench). Make sure master cylinder does not go dry!!! Unbolt slave cyliner from tranny, bolt new part on. Install hydraulic fluid line. DO NOT OVERTIGHTEN. Properly bleed system. Now your finished!
bleed your lines,may be air in them
There is no bleed screw on the 3.4 clutch. You have to unbolt the slave cylinder from the trans and drop it down so that it and the line are lower than the master cylinder, then pump the piston in/out to force any trapped air up to the master cylinder.
You do not reset a master cylinder. You should bench bleed it before installing.
Need to know how to assemble 95 Chevy clutch master cylinder?
after the clutch master cylinder has been replaced.
1. bleed the brakes. That means, make sure you have fluid in the reservoir, have a helper press the brake pedal while you open the bleed valve on the brakes, close the valve then have the helper let up on the brake pedal. Repeat the procedure until you don't detect air in the fluid. To do that you'll need to keep watching the reservoir.2. IF you keep getting air in the brake line, you may need to replace the master cylinder. Sometimes a failed master cylinder will suck air.
get a new one then bleed your brakes A new Ford master cylinder must be bench bled before it is installed, or it will be impossible to bleed the system later.
did you replace the master cylinder if so it has to be bleed frist
Air in system? Remove and bench bleed master cylinder Bleed lines and calipers
You have to refill it and bleed all over again ,every line. Make sure you fill master as you bleed.
Bleed the furthest from the master cylinder 1st then the rest in order of distance from the master cylinder.
