AMS Automotive Prefilled Master Cylinder PM0724

Possibly just the one I received, after install. System fully bled all was fine. Master started squeaking, then daily sitting starts to lose pedal. Pump a few times then better. Did a vacuum bleed at master all good for awhile. No air in system at all.

Fit perfect on a 2002 ford Ranger 4.0l. I bench bled it to make sure no air some how made its way in during shipping, but I did not need to. The shipping was also much faster than expected.

Workes very well, thanks.

Kit was good and worked good, easy to replace everything, but the only reason I didn’t give it a 5 star is because it didn’t come with a new switch when it was advertised it did came with one

showed the item included a new pedal switch was not in the box

This is a complete assembly including being pre filled with fluid. It is nice that they include the switch since a new switch is easy to install while replacing the master cylinder assembly.The description implies this is a master and slave package, but it only includes the master cylinder, reservoir and connection tubing. It is properly designed to install on vehicles listed without having to rebend any of the tubing, but be sure to "bench bleed" this before installation as air will have worked its way into the system during shipping, and the design of the vehicles this system is used on makes it impossible to properly bleed this when installed.

The product cracks below freezing temps.I experienced the issue twice.

Worked well, no issues. 2004 Ford Ranger, 5spd, 3.0l V6, USA
