Well, the homemade pressure bleeder didn't work. Okay, well it did work, but I can't do it as I read on the 'ol internet. (Basic idea: use compressed air to force brake fluid thru a clear piece of tubing sticking through your master cylinder cap.)

Problem is, the stock cap cannot hold the pressure! All the brake fluid poured out around the edge of the cap, and I didn't notice until I walked to the front of the car and saw the puddle.

The many websites I read about with that procedure had the newer master cylinders- with the screw-on cap instead of the rectangular push-on. Apparently theirs could hold the pressure nicely.

All's not lost tho, I'm working on a new design. As soon as I perfect it, and try it, I'll let y'all know.

If this second design doesn't work, eff it, I'm gonna bring my car to my tire shop and say "pressure bleed it!"

lol.. just grab a set of one man bleeder fittings, they screw right in where your old ones did, you loosen em up and its a one way valve, even has a barb on it to hook to a peice of hose to catch fluid.. cost is about 15 bux a pair i think...

 

Actually I'm thinking there's air trapped inside my master cylinder. Repeated bleedings of all four wheels shows clear, airless fluid... which doesn't explain why I get all those air bubbles in the m/c after I smack the brake pedal a few times.

hrmm a bad master cylinder will do that wont it? im really not all that knowledgeable on the workings of the brake system, i just know how to bleed them and change them.. heheh

 

While it might, there'd be other much worse signs (no brakes, pedal sinking to floor at a stop, etc) of it being bad. Good thing for this "new design" I'm doing, otherwise I'd have nothing to draw in the margins of my class notes! I discovered my first take of the new design would've trapped air in the tool; now I think I have to use a master cylinder reservoir from a junkyard car- one with a screw cap- on top of the tool. Hm...
