Review on Dorman M390096 Brake Master Cylinder by Donnie Boss

The part fits and works perfectly. The "soft" brake pedal travel was eliminated, and for the first time in a very long time I was able to lock the van's front wheels in either direction during post-installation testing. at NAPA and get a universal bleed kit. Other master cylinder replacements I've done in the past have included this. NOTES: 1) When you replace the master cylinder for the first time, some replacement parts do not come with the reservoir, so you need to remove the old one and install it on your new replacement. 2) If you have an assistant, make sure he (or she) pushes the plunger all the way down a couple of times to expel the remaining air from the block.
