Alright so when i got this shell from my brother one of the hardlines was blown out so he took them out to paint the engine bay, but never finished anything so i took over..

Anyways its got a Da master cylinder and brake booster in it and i put my hardlines from a 89 dx hatch in it. Also it has goodridge steel braided brakelines and a rear disk conversion. First of all when i put the master cylinder on it didnt just slide on i had to push it in and put the nuts on and tighten it.
I put mc gasket on too

Also i did bench bleed the mc.
I pumped the brakes a lil and it started taking fluid then stopped and wouldnt take anymore so i got someone to hold the brake and i cracked the bleeder and nothing came out not even air. It wont take anymore fluid idk why fluid is not even in the softlines yet i dont think. I tried gravity bleeding it and the fluid didnt move either. This is my first time bleeding brakes that have no fluid in them at all.

What am i doing wrong? I feel like im forgetting something important? lol
Anyhelp would be apreciated
thanks

 

Sounds like you don't bleed brakes that often... Anytime you start with a completely fresh system (and don't have the high dollar tools) it's best to just take out/extremely loosen the bleeders on all four corners. Let it sit for a while - if they start to gravity bleed then tighten the bleeders back up and proceed to bleed the brakes. If they don't gravity bleed then with them all loose/removed, slowly press the brake pedal (multiple times) to see if fluid will come out. If fluid comes out some but not all there is a blockage. If fluid comes out only on the front or only on the rear there is a possibility the master cylinder is bad, there is a blockage, or the master cylinder didn't get bled right. If fluid doesn't come out of any line there is a possibility the master cylinder didn't get bled right or the master cylinder is bad. If you are unsure of your lines - disconnect them at both ends and blow compressed air through them.

 

whenever i have trouble getting a fresh master bled on the car i crack the lines loose at the master and just do slow pumps to make sure the fluid is moving then re-tighten and proceed with a gravity bleed then normal bleed procedure

 

Yeah i hate brakes.
anyways thanks i give all that a try.

 

i also just replaced my master cylinder, and had a similar question. I primed the new master cylinder and installed it a few days ago, but when i went to bleed my breaks (starting with the furthest wheel from master cylinder) it was beautiful! Not even one little bubble. did it about 5 times just to make sure it wasn't too good to be true, no bubbles at all. I proceeded to do the other 3 wheels and got the same results. Not a single air bubble.

Is this too good to be true? I would think that there would be air in the lines after removing a master cylinder and putting a new one on... but then again this was my first time so i dont know.

been drivin around for a week now and brakes feel fine, no more brake fade (which is why i replaced MC in first place)

any thoughts?

 

Sounds like your good to me.

Also that fixed my problem guys thanks alot.

 

I've had this as well (on my old integra), as long as the lines are still full, swapping the master cylinder barely introduces any air into the system. Especially if you bench bleed the MC properly.

But don't take this the wrong way! You should ALWAYS bleed the system after opening it
