Review on Dorman M71245 Brake Master Cylinder by Ben Boulanger

Dude, that's ridiculous. I'll call them Monday to see if they are familiar with the issue and get a warranty replacement. The previous ones expired after about 10 months. If you have a soft pedal I bet this is your problem. Pull on your master and look from behind to see if it's wet. It worked fine at first, then I noticed the whistle pedal getting soft (will still stop, but the pedal wasn't as hard as it was originally). I drew this substance and noticed the liquid on the back where the booster pusher presses on it.
