I had to replace to brake hose on the right front . I went to bleed the air but the nut wont open. I know it will break if I force it. Can I bleed from the banjo bolt where the rubber hose goes in the caliper? Do I need to bleed all wheels or just the one where I replaced the hose.

 

So the bleeder nut broke off so is there anyway to proceed without replacing the caliper. The brake pedal still has no pressure, I was going to bleed the other wheels but I am sure those will all snap off too. Why do they make such an important part such a fragile piece of ****? Do I really need to replace all four calipers to bleed the brakes?? The back wheels are drum can you even replace those??

 

The one you broke off is pretty much done for unless you want to attempt to extract whats left of it. If you drill it out I wouldn't trust thread inserts on a caliper.

Penetrating oil and heat are your friend, these are brakes after all they go through 1000s of heat cycles. Get hot apply oil, and as it cools let it pull the penetrating oil into the threads. Old timers used wax to the same effect, repeat indefinitely. Also only use tools that properly fit the bleeder a 6 point socket with a tight tolerance is ideal. That means no 12 point sockets, no crescent wrenchs, no vice grips unless you want it to be round.

 

Replace the caliper. May cost some money but it's much easier than trying to repair the bleeder valve.

 

I will start by replacing the front right caliper. I have a feeling that air got into the master cylinder when the fluid went down because I did bleed the front right through the banjo bolt and the pedal still had almost no pressure at all. So if I have to bleed all the wheels I will have to throw away both good front calipers and do both rear wheel cylinders all because of a simple leaking hose that should have taken 5 minutes to fix.

 

i wouldnt throw them away, a lot of times you will need them for core charges. yes, you have to bleed through the bleeder valve. as others have said heat and penetrating oil over and over. of the 4 stuck bleeder valves i only broke the first one, i was much more careful with the others and they came out fine.
