Brake bleeding?

Hello,

I have just completed putting on all new brakes on my yj and even after bleeding the system 6 times I can't get a stiff pedal going. What do I need to do?

Thanks,
Jake

are the bleed screws on the calipers facing up?

Did you bench bleed the master (if you replaced it)

Yes and it's the original master however everything else is brand new. New wheel cylinders,drums,hardware,shoes,rotors,calipers, pads, and lines all new. And would it be necessary to bleed the old master, or is there a fluid resivor in the master that could be low?

I had an issue with the callipers when I ha them upside down. Went through three litres if fluid bleeding them. If everything is good bleed them again

Sent from my iPhone, probably because I am bored at work.

Did you manually adjust the rear brake shoes?

Did you bleed the brakes in the following order:
passenger's side rear, drivers side rear, passenger side front, drivers side front?

If you drained the MC it needs to be bench bled again also.

One other reason for soft pedal can be mushy brake hoses

Do you know what was good about the good old days? I wasn't good, And I wasn't old!

Add fluid

In post #4 you ask about a reservoir. Yes, you need to put fluid into it while you are bleeding the lines. If you don't then you will end up with air in the master cylinder and have to bleed the master and start all over again with the lines.

Agreed! If you failed to add brake fluid WHILE YOU WERE BLEEDING YOUR BRAKES, you weren't bleeding them, you emptied the entire brake system of brake fluid! The MC reservoir should never be allowed to become empty in the brake bleeding process. That introduces air into the brake system.

And no I won't go with you for a test ride on that steep, narrow mountain road near your home when you are done with this brake job!
