How To Fix a Spongy Brake Pedal Chevy Truck -EricTheCarGuy

In truth, this is a video about how to replace and bleed a master cylinder on a C1500, 1990 5.7L to be specific. However, I do have information on how you can solve a spongy brake pedal on one of these trucks by replacing the master cylinder and booster with parts from a later model truck.

Here are those part #’s

Master Cylinder: M390259

Booster: 5471046
