Dorman M630154 Brake Master Cylinder- Enhanced Performance & Reliability Review

The illustration clearly shows the master brake cylinder with expansion tank. It doesn't come with a tank. Obviously false advertising.

I'm not sure what I received was actually a Dorman part as it didn't come in the original packaging. However, it fits perfectly and seems to work as expected for the aftermarket.

Our car stalled at 60 mph on the freeway. We felt it was important to be a hybrid. Luckily it was just a pump. The item arrived quickly and was easy to assemble. Now the car runs like a champ again! I will definitely use this company again!

Part works great so far, great factory replacement. It dies in a cone with a reservoir and cap as shown, but what you don't get is a liquid level sensor. When installing, just be careful not to damage the existing sensor. You are tender.

perfect for my grand cherokee. Easy installation. The kit did not include a reservoir, but could easily move the stock reservoir to a Dorman master cylinder. This did not come with a bleed kit; I bought a bleed kit from Autozone and then clear tubing from Menards (the bleed kit came with black tubing - what? - I can't see any air bubbles through the black tubing as my Superman x-ray scope has stopped working.
