Ok.. here are the deets:
1978 280z w/ SU's
Front Disk, Rear Drum
1. When I bought the car, braking would be non existent until the pedal reached near the floor, then it would lock up. I found out that I was missing the Reaction Disk. Reaction disk is now permanently in place on the back of the push rod.
2. After a complete motor build about a year later, it's almost time to get this thing on the road. So I go to inspect the brakes and the pedal is a sponge, and goes to the floor. So I figure, time to bleed the brakes. The front brakes flow very well when I bled them and there was very few bubbles. I proceeded to the rear drums. I was getting very little fluid on both sides. No where near the flow as the front brakes. Why is this?? The fluid in the MC is full. There are no signs of leaks from the proportioning valve.
**** I found out I was missing the check valve in between the booster and the intake manifold. How much of a different would this make? (P.S. - Just ordered it so it's on the way to be installed)
3. Here's the kicker.
-Front Left Brake: Works perfectly
-Front Right Brake: Slight grasp as the pedal is on the floor.. but still easily able to turn the wheel.
-Rear Left Brake: No braking at all
-Rear Right Brake: No braking at all
4. There is not a single leak that I can see anywhere, and the MC is full of fluid. Pumping the brakes and the MC fluid level stays the same. So I don't see why hardly any fluid is getting to the rear drums!
I don't think I left anything out, If I did please let me know. Any help will be greatly appreciated. THANKS!!
