🔧 Dorman M39810 Brake Master Cylinder: Top-Quality Replacement for Enhanced Braking Performance Review

Product worked perfectly. Installation was easy and came with a cover unlike other BMCs I've bought elsewhere. The price was unbeatable

The unit was perfect for my S13 to replace a leaking BMC that was removing paint from my engine bay. It's very easy to pump on the bench, pedal feel hasn't changed (well, it's actually better since it doesn't leak), and there haven't been any installation issues. The best price I could find and I am very happy with the purchase.

Installed on a 1989 Nissan 240SX. It was supposed to bleed, but that made it easy. All I had to do was push the plunger with a blunt rod until the bubbles stopped. I didn't even put it in a vise. However, I had to push the plunger way more often than I intended. Read the instructions. But it works great and is surprisingly cheap when Big O charged $417 to replace it!
