brake project

Check your rubber hoses and make sure they arent cracked or otherwise damaged. Bench bleed the master cylinder before installing. Then bleed the passenger rear until no air bubbles then the left rear, then the right front, and finally left front. Done. I would also use DOT 5 silicone fluid. Expensive as heck but you wont ever have problems with the brake cylinders, flush the lines if you do - to clean out the old DOT 3 or 4. DOT 3 and 4 is hydroscopic, DOT 5 is silicone fluid and wont rust the cylinders as a result.
