Hi everyone,
66 Mustang coupe, 289/auto, factory disc brakes up front, rear drums.
So I've had the car fully up on jack stands for 3 or 4 months doing some work to the rear and suspension, but haven't touched the braking system at all. Finally got finished everything I was working on, lowered it back to the ground with the wheels on and... no brakes. Pedal went to the floor. I checked the master cylinder and it's practically empty.
Something had to be leaking right? So I go check all 4 brakes, they're all bone dry. Checked under and around the master cylinder, booster and distribution block... bone dry. Where the heck did the fluid go? Prior to any of this I had braking but it was always kind of spongy even with the disc brakes up front.
So I refilled both bowls and proceeded to bleed the brakes. Did the rear right and rear left no problem, finally got some pedal back. Bled the front passenger side and lost all pedal. I notice now when I depress the brake pedal with the cap off the MC, I get bubbles from the main bowl, and fluid actually squirts out of the secondary front bowl. With the cap on fluid actually leaks past the seal on the cap. It's my understanding that the fluid shouldn't really be sloshing around in there, right?
Any idea about what's going on??
