Review on 🔧 Dorman M390337 Brake Master Cylinder - Brand New for Optimal Performance by Brett Islam

The master cylinder never worked. Bench bled out like I should have. Installed, and the pedal still hit the floor. It's too late for me to send it back, so it's basically a warning. The price is good. If you bought one and your brakes still don't work, have them replaced before you spend tons of money on other things. Brand new calipers all around. New brake lines. New ABS module. Completely new braking system. The pedal still hits the floor. Back to the master cylinder. Has been replaced by a more expensive brand. Now it works fine.
