bleeding brakes 99 chev pu Sign In

I replaced the right front brake line on my 99 chev pu 1500. I had to take two other lines loose from the distribution block under my cab to get to the one I was replacing. After replacing everything and filling the reservoir I started bleeding the brakes starting with the right rear. the two rear brakes bleed normally but the right front bleeds air only for the most part.Also the pedal does not pump up tight before I crack the bleeder. I did spliced the line not replace the whole thing. I have checked for leaks and find none.Any suggestions?

Was this a rusted line problem?

Don't you just hate the rusted line thing especially on trucks?

Ok: I trust you spliced in line flaring in new line with flare nuts and unions as needed. You do know the compression plumbing stuff is not the correct way?

It may have been so low on fluid that master was real dry and it could be like bench bleeding again. Try with it in place to just crack open the line closest to booster (that's for fronts) as if you are bleeding it there and it may just start to behave for you at the wheel. If not I'd try to "bench" bleed it in place first as it sits fairly level in this application.

There's a chance that if a line blew out that when your foot goes to floor and again now while trying to bleed that the master cylinder had some crust deeper in its bore than it was accustomed to using and has torn up seals in the master cylinder hence behaving now as a bad master cylinder.

Some just misbehave to get started and some don't. Keep at it and it should begin and bleed out properly. If still trouble there are some other tricks and even a power bleeder that clamps to top of master to assist,
