I have a pressure bleeder, but can't seem to get that sponginess out of my system. The brakes go to the floor before they grab and if I ever have to slam on the brakes, I'm screwed.
My question is this...
If I'm using the pressure bleeding system, what's the point in bench bleeding the master cylinder? When you put the pressure bleeder on it, the reservoir obviously isn't filled to the brim, so whatever air is in there is just going to get pushed right into the master cylinder bore.
The only way I can see to get around this is to buy a new master cylinder with a bleeder screw in the bore.
What do you guys do?

 

It makes life alot eazyer to bench bleed the master cylinder.......another thing to try when bleeding your brakes is to tap on the caliper/wheel cylinder with the bleeder open as this will help get the small air bubbles out.If you have bleed it right and still get the spongy feel your master cylinder may be bypassing internaly.Since you are asking about bench bleeding the master I'm guessing you just got a new one....but new parts aren't always good parts trust me.I had a customer one time that I went to there wearhouse to fix a forklift and it originaly had a bad coil.....replaced it...still no start......after three "new" coils I found one that was good.
Good luck,
Mike
