Brake issue - Non Mitsubishi related warning :)

[blaze_125]

So here it goes...

The front calipers on my 93 Honda were seized. The slider pins where seized and the whole assembly had a hard time... The car was braking fine, but I had to pass a safety check and my calipers failed... even though I could brake just fine.

So I got my-self 2 calipers from the local junker.
I removed the old calipers from the car and bled the lines leaving barely any fluid in the master cylinder.
I installed the "new" calipers and I'm having the following issue:

If the engine is not running, I can pump the brake pedal and build up pressure in the braking system.

If the engine is running, I can't get any pressure buildup.

What's your take on this?

I bled the system twice already, but I'll do it a third time tonight.

well from waht you stated above it sounds like you have a lot of air in your brake lines. the reason for that is when you bleed the brakes and you let the master almost empty out you allowed air in. when you pump the brakes with the car of you will get a hard brake pedal. but when you turn the car on you hvae a spongy brake pedal. i wouuld gravity bleed all your brakes. and make sure you keep the master cylinder full. if you have any questions let me know.

I read gravity blead a few times in multiple different places... I have yet to understand the actual concept...

Do I do all 4 wheels at the same time?
I just open the bleeder and let it drip?
How long does it usuall take to gravity bleed? I'm not in a hurry, I just want to make sure I don't close the bleeder too early.

Edit:
I just found my Honda manual and it turns out I bled in the wrong order. Who knows, maybe that's the problem. I have a hard time beleiving it could be anything else than air since everything was working fine before I took the calipers appart. In my mind it's either gotta be a huge air bubble sitting somewhere in the line, or bad calipers. Although I don't know how a bad caliper could create that sort of problem(it does not appear to be leaking).

There is an order by which you have to bleed your brakes. Start from the farthest from the master cylinder and work toward the closest. So rear pass, rear driver, front pass, front driver.

Third time's a charm!
I bled the brakes a third time yesterday night and everything came back to normal

Oh... and I safetied the car this morning
For the next few months, the Lancer will be the rainy day car, and the Honda gets her "dry/warm day" spot back.
